In a 4-day period (August 7-10), approximately 270,000 m<sup>3</sup> of rockfall debris accumulated in Makaopuhi's west pit, representing a total kinetic energy release of about 101B ergs. Because the rockfalls happened within an area with an established seismic network, it was possible to correlate the seismic record of the rockfalls with onsite field observations. The seismic signatures of rockfalls are generally distinguishable from those of earthquakes and other recorded events. Approximate magnitudes determined for some of the largest rockfalls range from 0.8 to 1.2, corresponding to calculated seismic energy releases of 2X10<sup>11</sup> to 10X10<sup>11</sup> ergs, if the magnitude-energy relationship for earthquakes is applicable to rockfalls. The August 1972 swarms of rockfalls at Makaopuhi correlate in time not with moderate or large earthquakes but rather with local eruptive activity and are inferred to have been caused by eruption-induced modifications of stress patterns of the crater walls. However, the amount and nature of the stress change required to exceed the threshold stability of the crater wall and to trigger a rockfall flurry cannot be determined. The Makaopuhi activity is typical of most major rockfall episodes in other Kilauean pit craters in recent years, which also have been associated with volcanic activity, particularly during times of changes in eruptive behavior.</p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Tilling, R.I., Koyanagi, R.Y., and Holcomb, R.T., 1975, Rockfall seismicity correlation with field observations, Makaopuhi Crater, Kilauea Volcano, Hawaii: Journal of Research of the U.S. Geological Survey, v. 3, no. 3, p. 345-361.","productDescription":"17 p.","startPage":"345","endPage":"361","costCenters":[],"links":[{"id":403186,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403184,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1975/vol3issue3/report.pdf","size":"22359 KB","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Hawai'i","otherGeospatial":"Kilauea Volcano, Makaopuhi Crater","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.16729354858398,\n              19.35985853308795\n            ],\n            [\n              -155.16458988189697,\n              19.36062781661234\n            ],\n            [\n              -155.16240119934082,\n              19.362409301365904\n            ],\n            [\n              -155.16175746917725,\n              19.363866865322365\n            ],\n            [\n              -155.16167163848874,\n              19.365526852845328\n            ],\n            [\n              -155.16252994537354,\n              19.36767266532593\n            ],\n            [\n              -155.16390323638916,\n              19.368684831219216\n            ],\n            [\n              -155.16570568084717,\n              19.369373100436274\n            ],\n            [\n              -155.16669273376465,\n              19.369332614092194\n            ],\n            [\n              -155.16634941101074,\n              19.370020880573616\n            ],\n            [\n              -155.16772270202637,\n              19.370466227924478\n            ],\n            [\n              -155.16982555389404,\n              19.370223311338513\n            ],\n            [\n              -155.17119884490967,\n              19.36908969581655\n            ],\n            [\n              -155.17343044281006,\n              19.369494559408146\n            ],\n            [\n              -155.17596244812012,\n              19.36908969581655\n            ],\n            [\n              -155.17755031585693,\n              19.367146336577406\n            ],\n            [\n              -155.17712116241455,\n              19.364960029737954\n            ],\n            [\n              -155.1756191253662,\n              19.363300036443277\n            ],\n            [\n              -155.17197132110596,\n              19.361194654781624\n            ],\n            [\n              -155.16729354858398,\n              19.35985853308795\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"3","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Tilling, Robert I. 0000-0003-4263-7221 rtilling@usgs.gov","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":2567,"corporation":false,"usgs":true,"family":"Tilling","given":"Robert","email":"rtilling@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":846022,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Koyanagi, Robert Y.","contributorId":52561,"corporation":false,"usgs":true,"family":"Koyanagi","given":"Robert","email":"","middleInitial":"Y.","affiliations":[],"preferred":false,"id":846023,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Holcomb, Robin T.","contributorId":46938,"corporation":false,"usgs":true,"family":"Holcomb","given":"Robin","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":846024,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

An evaluation of structures developed during the late Cenozoic fails to explain the erratic distribution of seismicity. An evaluation of the late Cenozoic stratigraphy, however, shows a concentration of relatively impermeable evaporite beds and fine-grained clastic strata in the less seismic part of the lake basin; therefore, the authors conclude that a hydraulic connection between the lake water and the deep aquifer system that includes buried faults is needed in the Lake Mead area to cause the release of seismic energy. Where hydraulic connection is prevented by continuous or quasi-continuous upper Cenozoic basin-fill strata of low permeability, as in the eastern basin area, seismicity does not occur.</p>","language":"English","publisher":"U.

To accommodate residential use, a proposal has been made by developers to the Board of the Lake Worth Drainage District to lower the canal stages in the interior part of the area undergoing change. This report documents one of the possible effects of such lowering. Of particular interest to the Board was whether the lower canal stages would cause an increase in salt-water intrusion into the shallow aquifer along the coast. \r\n\r\nThe two main tools used in the investigation were a digital model for aquifer evaluation and an analytical technique for predicting the movement of the salt-water front in response to a change of ground-water flow into the ocean.\r\n\r\nThe method of investigation consisted of developing a digital ground-water flow model for three east-west test strips. They pass through the northern half of municipal well fields in Lake Worth, Delray Beach, and Boca Raton. The strips were first modeled with no change in interior canal stages. Then they were modeled with a change in canal stages of 2 to 4 feet (0.6 to 1.6 metres). Also, two land development schemes were tested. One was for a continuation of the present level of land development, simulated by continuing the present pumpage rates. The second scheme was for land development to continue until the maximum allowable densities were reached, simulated by increasing the pumping rates.\r\n\r\nThe results of the test runs for an east-west strip through Lake Worth show that lowering part of the interior canal water levels 3 feet (1.0 metre), as done in 1961, does not affect the aquifer head or salt-water intrusion along the coastal area of Lake Worth. As a result, no effect in the coastal area would be expected as a result of canal stage lowering in other, interior parts of the study area.\r\n\r\nResults from the other test runs show that lowering interior canal water levels by as much as 4 feet (1.2 metres) would result in some salt-water intrusion for either land development scheme. Salt-water intrusion is dependent on the location, and amount of water withdrawn, from well fields.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr7574","collaboration":"Prepared in cooperation with the Central and Southern Florida Flood Control District and Lake Worth Drainage District","usgsCitation":"Land, L.F., 1975, Effects of lowering interior canal stages on salt-water intrusion into the shallow aquifer in southeast Palm Beach County, Florida: U.S. Geological Survey Open-File Report 75-74, 59 p., https://doi.org/10.3133/ofr7574.","productDescription":"59 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":148208,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0074/coverthb.jpg"},{"id":998,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0074/ofr7574.pdf","text":"Report","size":"3.66 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Florida","county":"Palm Beach County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -80.23555755615233,\n              26.337422286477317\n            ],\n            [\n              -80.20362854003906,\n              26.327575955050822\n            ],\n            [\n              -80.15796661376952,\n              26.327883665584135\n            ],\n            [\n              -80.13118743896484,\n              26.32849908419746\n            ],\n            [\n              -80.12638092041014,\n              26.66955020082152\n            ],\n            [\n              -80.21942138671875,\n              26.671697757254027\n            ],\n            [\n              -80.2163314819336,\n              26.517892099592242\n            ],\n            [\n              -80.22285461425781,\n              26.514512811622374\n            ],\n            [\n              -80.2218246459961,\n              26.468114356372276\n            ],\n            [\n              -80.23796081542969,\n              26.407860638241498\n            ],\n            [\n              -80.23555755615233,\n              26.337422286477317\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"https://www.usgs.gov/centers/car-fl-water\" data-mce-href=\"https://www.usgs.gov/centers/car-fl-water\">Caribbean-Florida Water Science Center</a><br>U.S. Geological Survey<br>3321 College Avenue<br>Davie, FL 33314</p><p><a href=\"../contact\" data-mce-href=\"../contact\">Contact Pubs Warehouse</a></p>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db611c6c","contributors":{"authors":[{"text":"Land, Larry F.","contributorId":60612,"corporation":false,"usgs":true,"family":"Land","given":"Larry","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":169704,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Prior to development the area was poorly drained. By 1974, more than 150 miles (241 kilometres) of drainageways had been constructed to drain the area.\r\n\r\nThe water-bearing formations underlying Lehigh Acres include the water-table, sandstone, lower Hawthorn, and Suwannee aquifers. The water-table aquifer is usually not more than 30 feet (9 metres) thick; it contains water of relatively good quality, except for iron and color. Water levels in this aquifer probably have been affected by construction of drainage canals. The sandstone aquifer, used extensively throughout the area as a source of water supply usually contains water of good quality although the water is hard and in places may contain concentrations of dissolved solids and iron which exceed the recommended limits of the U.S. Public Health Service and the State of Florida for drinking water. The lower Hawthorn and Suwannee aquifers, usually encountered at depths between 440 and 850 feet (135 and 262 metres), contains water with relatively high concentrations of sodium, sulfate, chloride, and dissolved solids.\r\n\r\nThree streams, the Orange River, Hickey Creek, and Bedman Creek and the canals connected to them, provide drainage of the area. Except for the Orange River, where the water is of good chemical quality, little is known of the water quality. Similarly, little information is available on stream discharge except for the Orange River where the average annual discharge was 41.1 cubic feet per second (11.6 cubic metres per second) between 1935-46.\r\n\r\nMost lakes and ponds in Lehigh Acres are hydraulically connected to the water-table aquifer such that factors which affect one also affect the other. Theoretical drawdown curves indicate that the drainage canals may affect ground-water levels to a distance of 6,000 feet (1,800 metres) under certain conditions. Leeland Lake, the only known sinkhole lake in Lee County, is about 208 feet (64 metres) deep and contains water more nearly similar to the sandstone aquifer, although the lake may by hydraulically connected to both the water-table and sandstone aquifers.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr7555","collaboration":"Prepared in cooperation with the Florida Department of Natural Resources, Bureau of Geology and the Board of County Commissioners of Lee County","usgsCitation":"Boggess, D.H., and Missimer, T., 1975, A reconnaissance of hydrogeologic conditions in Lehigh Acres and adjacent areas of Lee County, Florida: U.S. Geological Survey Open-File Report 75-55, 88 p., https://doi.org/10.3133/ofr7555.","productDescription":"88 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":145721,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0055/coverthb.jpg"},{"id":975,"rank":100,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0055/report.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 75-55"}],"country":"United States","state":"Florida","county":"Lee County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -81.78840637207031,\n              26.492084108599812\n            ],\n            [\n              -81.56181335449219,\n              26.492084108599812\n            ],\n            [\n              -81.56181335449219,\n              26.679980810428834\n            ],\n            [\n              -81.78840637207031,\n              26.679980810428834\n            ],\n            [\n              -81.78840637207031,\n              26.492084108599812\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"https://www.usgs.gov/centers/car-fl-water\" data-mce-href=\"https://www.usgs.gov/centers/car-fl-water\">Caribbean-Florida Water Science Center</a><br>U.S. Geological Survey<br>3321 College Avenue<br>Davie, FL 33314</p><p><a href=\"../contact\" data-mce-href=\"../contact\">Contact Pubs Warehouse</a></p>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a8600","contributors":{"authors":[{"text":"Boggess, Durward Hoye","contributorId":13243,"corporation":false,"usgs":true,"family":"Boggess","given":"Durward","email":"","middleInitial":"Hoye","affiliations":[],"preferred":false,"id":166598,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Missimer, T.M.","contributorId":41839,"corporation":false,"usgs":true,"family":"Missimer","given":"T.M.","email":"","affiliations":[],"preferred":false,"id":166599,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The avalanches traveled nearly identical paths 2.0-2.6 km down Boulder Glacier on the east slope of the volcano. Debris from at least one past avalanche can be seen as a thin bed of acidic mud in the glacier terminus. Fumaroles. thermal springs, and areas of warm ground, some of which are subglacial, are concentrated in the crater and were mapped by aerial infrared thermography. The outgoing radiant flux per unit area from a cluster of infrared anomalies within 50-150 m of the avalanche source was estimated to be 319 W m<sup>-2</sup> (7,620 <i><span>μ</span></i>cal cm<sup>-2</sup>s<sup>-1</sup> ) in November 1972, which is sufficient to account for observed ice perforations. In addition vapor emission, not apparent in thermography, was observed along the source margin after the avalanche of August 1973. The principal conditions that produce the avalanches are considered to be the large accumulation of snow and firn on top of hydrothermally altered clay-rich ground at Sherman Peak and the saturation near the ground-firn interface by melt water produced both by summer snow ablation and by geothermal emission. The periodic avalanches have a potential for impounding water in the crater in addition to ponded water already known to occur. Sudden release of impounded water could present a danger to the Boulder Creek valley below. </p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Frank, D., Post, A., and Friedman, J., 1975, Recurrent geothermally induced debris avalanches on Boulder Glacier, Mount Baker, Washington: Journal of Research of the U.S. Geological Survey, v. 3, no. 1, p. 77-87.","productDescription":"11 p.","startPage":"77","endPage":"87","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":403398,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":403397,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1975/vol3issue1/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Washington","otherGeospatial":"Boulder Glacier, Mount Baker","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.91116333007811,\n              48.73037931457286\n            ],\n            [\n              -121.75048828124999,\n              48.73037931457286\n            ],\n            [\n              -121.75048828124999,\n              48.828565527993234\n            ],\n            [\n              -121.91116333007811,\n              48.828565527993234\n            ],\n            [\n              -121.91116333007811,\n              48.73037931457286\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"3","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Frank, David dfrank@usgs.gov","contributorId":170058,"corporation":false,"usgs":true,"family":"Frank","given":"David","email":"dfrank@usgs.gov","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":846214,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Post, Austin","contributorId":90709,"corporation":false,"usgs":true,"family":"Post","given":"Austin","affiliations":[],"preferred":false,"id":846215,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Friedman, Jules D.","contributorId":76757,"corporation":false,"usgs":true,"family":"Friedman","given":"Jules D.","affiliations":[],"preferred":false,"id":846216,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The ESIAC system developed by the Stanford Research Institute, was used to obtain enlargements and false-color renditions of turbidity plumes. After projection on a video screen, individual turbidity features were analyzed, mapped, and photographed.</p><p>The Niagara River plume, as much as 500 square kilometres in area, is by far, the largest turbidity feature in the lake. Based on image tonal comparisons, turbidity in the Welland Canal is usually higher than that in any other watercourse discharging into the lake throughout the shipping season. Somewhat less turbid water enters the lake from the Port Dalhousie diversion channel and the Genesee River. Relatively clear water resulting from the deposition of suspended matter in numerous upstream lakes is discharged by the Niagara and Oswego rivers.</p><p>Plume analysis corroborates the presence of a prevailing eastward flowing longshore current along the entire south shore. This current is most persistent at the Oswego River outlet but is quite variable in the Rochester embayment, where rapid shifts in water movement were occasionally detected in LANDSAT images. The position of the spring thermal bar, a zone, of maximum density water corresponding to the 4°C isotherm, was approximately located in images obtained during April 1973. Although eastward moving currents were detected on the inshore side of the thermal bar, westward moving counter currents seem to be dominant along its offshore side.</p><p>Plumes generated by beach erosion were readily detected in the images. Such areas are identified by light to very light, long, narrow plumes paralleling the coastline. Extensive areas of the south shore are subject to erosion, but the most severely affected beaches are situated between Fifty Mile Pt., Ontario and Thirty Mile Pt., N.Y., along the Rochester embayment, and between Sodus Bay and Nine Mile Pt.</p><p>Color illustrations of figure accession numbers EDC-010077 to EDC-010106 are available for purchase from the EROS Data Center, Sioux Falls, South Dakota 57198.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr75249","collaboration":"Prepared in cooperation with the National Aeronautics Space Administration/Goddard Space Flight Center, Greenbelt, Maryland","usgsCitation":"Pluhowski, E.J., 1975, Dynamics of turbidity plumes in Lake Ontario: U.S. Geological Survey Open-File Report 75-249, Report: ix, 59 p., https://doi.org/10.3133/ofr75249.","productDescription":"Report: ix, 59 p.","costCenters":[],"links":[{"id":149041,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0249/report-thumb.jpg"},{"id":462666,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0249/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"Canada, United States","otherGeospatial":"Lake Ontario","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -80.99172224212556,\n              45.15721980352575\n            ],\n            [\n              -80.99172224212556,\n              42.37218583599275\n            ],\n            [\n              -74.39757490950474,\n              42.37218583599275\n            ],\n            [\n              -74.39757490950474,\n              45.15721980352575\n            ],\n            [\n              -80.99172224212556,\n              45.15721980352575\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a59e4b07f02db62f706","contributors":{"authors":[{"text":"Pluhowski, Edward J.","contributorId":87911,"corporation":false,"usgs":true,"family":"Pluhowski","given":"Edward","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":171172,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The combined sightings of foxes and fox dens from the mid-May and mid-June searches were used to identify individual fox families. The number of fox families was used as the measurement of density. Dens, highly visible during the mid-May searches, were the most reliable family indicator; 84 percent of 270 families identified during the study were represented by dens. Adult foxes second in importance, were most observable during the mid-May searches when 20 to 35 percent of those estimated to be available were sighted. Adult sightings during other search periods ranged from 4 to 17 percent of those available. Pup sightings were the most variable family indicator, but they led to the discovery of some dens. Sources of error for which adjustment factors were determined are: den moves exceeding criterion established for the spacing of dens in a single family, overestimation of the number of fox families living near township boundaries, and the percentage of fox families overlooked during the aerial searches. These adjustment factors appeared to be largely compensatory.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3800462","usgsCitation":"Sargeant, A., Pfeifer, W., and Allen, S., 1975, A

Preseismic changes in elevation in the southern Transverse Ranges were almost uniformly positive and generally episodic. Maximum uplift measured between 1960/61 and 1968/69 was 0.205 m (observed) or 0.200 m (adjusted); it occurred about 30 km northeast of the 1971 epicenter. As much as 0.129 m (observed) of preseismic uplift was also measured about 30 km northwest of the epicenter between 1964 and 1968. A comparison between 1968 and 1969 elevation data revealed 0.078 m (observed) of differential uplift centered about 10 km west of the epicenter; earlier leveling indicates that this uplift began between February 1967 and May 1968. Changes in elevation measured during the interval 1968/69-71 (postearthquake) are interpreted as chiefly coseismic and were concentrated along a 15-km ruptured segment of the east-trending, north-dipping San Fernando fault. These changes were characterized by subsidence of as much as 0.111 m (observed) or 0.092 m (adjusted) south of the fault and a ridge of uplift of up to at least 2.195 m (observed) or 2.196 m (adjusted) immediately north of the fault. </p><p>The more episodic preseismic movements are interpretable as deep-seated creep events on the San Fernando fault. Alternatively, these episodic movements may be due partly to the operation of dilatancy; the onset of the 196849 epicentral uplift accords closely with the initiation of a <i>V</i><sub>p</sub>/<i>V</i><sub>s</sub> anomaly recognized in this same area. The 1968/69-71 elevation changes can be attributed almost entirely to slip on the San Fernando fault.

Rhyolitic domes 11-17 m.y. old are widespread, particularly in the easternmost part of the state and in adjacent parts of Idaho and Nevada. Domes younger than 11 m.y. occur principally in two 250-km-long belts that trend N. 75° W. On the basis of 47 K/Ar radiometric dates, the rhyolitic domes in and between these belts show a remarkably well defined monotonic age progression from less than 1 m.y. old in the west to about 10 m.y. old on the east. The progression in age of the domes is sufficiently well defined that the ages of the domes can be smoothly contoured and the age of most undated domes can be estimated to within 1 m.y. The age contours are oblique to the trend of the two belts; domes younger than 4 m.y. occur only in and near the northern belt. The rate of progression is about 1 cm/yr for domes younger than about 5 m.y. and 3 cm/yr for domes 5-10 m.y. old. The change in rate of progression about 5 m.y. ago is accompanied by a change in orientation of the age contours and in area of outcrop. Inferred vents for dated rhyolitic ash-flow tuffs younger than 10 m.y. are located in areas where domes are approximately the same age as the tuffs and thus also fit the age progression.</p><p>Most electric-power-producing geothermal fields in the world occur in or proximal to areas of young silicic volcanic rocks. On the basis of the well-defined age progression of rhyolitic domes in southeastern Oregon, silicic intrusive bodies sufficiently young to be heat sources for geothermal systems are likely only in the vicinity of Newberry Volcano at the west end of the northern belt of domes.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75348","usgsCitation":"MacLeod, N.S., Walker, G.W., and McKee, E.H., 1975, Geothermal significance of eastward increase in age of upper Cenozoic rhyolitic domes in southeastern Oregon: U.S. Geological Survey Open-File Report 75-348, ii, 22 p., https://doi.org/10.3133/ofr75348.","productDescription":"ii, 22 p.","costCenters":[],"links":[{"id":148828,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0348/report-thumb.jpg"},{"id":403155,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0348/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Oregon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.805419921875,\n              42.00032514831621\n            ],\n            [\n              -117.02636718749999,\n              42.00032514831621\n            ],\n            [\n              -117.02636718749999,\n              44.08758502824516\n            ],\n            [\n              -121.805419921875,\n              44.08758502824516\n            ],\n            [\n              -121.805419921875,\n              42.00032514831621\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac7e4b07f02db67af18","contributors":{"authors":[{"text":"MacLeod, Norman S.","contributorId":13643,"corporation":false,"usgs":true,"family":"MacLeod","given":"Norman","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":169985,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walker, George Walton","contributorId":14801,"corporation":false,"usgs":true,"family":"Walker","given":"George","email":"","middleInitial":"Walton","affiliations":[],"preferred":false,"id":169986,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McKee, Edwin H. mckee@usgs.gov","contributorId":3728,"corporation":false,"usgs":true,"family":"McKee","given":"Edwin","email":"mckee@usgs.gov","middleInitial":"H.","affiliations":[],"preferred":true,"id":169984,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Preliminary interpretations of geophysical data suggest that the buried ridge under the eastern edge of the AOCS in the Baltimore Canyon trough area is deeper and farther west than previously suspected. Although it is not observed under the seaward extension of the Cape Fear arch, this ridge can be traced from the south side of the Baltimore Canyon trough northeastward toward the eastern edge of the Georges Bank trough. In the Baltimore Canyon trough area, the ridge seems to be fault controlled and to form the eastern edge of a Mesozoic depocenter in which approximately 12 km of relatively undisturbed post-Paleozoic sediments accumulated. Below a depth of 6 km, rocks previously considered to be crystalline basement instead may be carbonate and/or evaporite sequences of Jurassic age or older which overlie an even deeper crystalline basement. More than 8 km of sediments are present beneath the continental shelf on Georges Bank. The preliminary regional geophysical studies indicate that thick marine sedimentary sections and geologic structures favorable for the accumulation of petroleum apparently exist under the AOCS off the northeastern part of the United States.</span></p>","language":"English","publisher":"American Association of Petroleum Geologists","publisherLocation":"Tulsa, OK","doi":"10.1306/83D91641-16C7-11D7-8645000102C1865D","usgsCitation":"Mattick, R., Foote, R.Q., Weaver, N.L., and Grim, M.S., 1974, Structural framework of United States Atlantic outer continental shelf north of Cape Hatteras: American Association of Petroleum Geologists Bulletin, v. 58, no. 6, p. 1179-1190, https://doi.org/10.1306/83D91641-16C7-11D7-8645000102C1865D.","productDescription":"12 p.","startPage":"1179","endPage":"1190","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":265528,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Atlantic outer continental shelf","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -84.0,25.0 ], [ -84.0,47.5 ], [ -60.0,47.5 ], [ -60.0,25.0 ], [ -84.0,25.0 ] ] ] } } ] }","volume":"58","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50f7da2fe4b0faa3ef21ec50","contributors":{"authors":[{"text":"Mattick, R.E.","contributorId":85162,"corporation":false,"usgs":true,"family":"Mattick","given":"R.E.","affiliations":[],"preferred":false,"id":471683,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Foote, R.

Mirex levels were greatest in Mississipi and Louisiana woodcock.     Pooling of birds and averaging of individually analyzed birds did not provide equivalent estimates of equivalent residues; pool values tended to be larger and more variable.  Levels of six chlorinated hydrocarbons and mercury were negatively correlated with the latitude of the collection site.  However, this relationship seemed weakest for PCB's.  Among eight chemical residues, PCB levels were most often correlated with levels of the other seven.

The strait may have been deeper, and there may have been no land bridge between the Seward Peninsula of Alaksa and the Chukotka Peninsula of Siberia during most of early and middle Pleistocene time.</p></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0033-5894(74)90039-8","issn":"00335894","usgsCitation":"Hopkins, D., Rowland, R., Echols, R., and Valentine, P.C., 1974, An Anvilian (early pleistocene) marine fauna from western Seward Peninsula, Alaska: Quaternary Research, v. 4, no. 4, p. 441-470, https://doi.org/10.1016/0033-5894(74)90039-8.","productDescription":"30 p.","startPage":"441","endPage":"470","costCenters":[],"links":[{"id":218698,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Seward Peninsula","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -168.00292968749997,\n              64.89558934777301\n            ],\n            [\n              -164.90478515625,\n              64.89558934777301\n            ],\n            [\n              -164.90478515625,\n              65.73965627227945\n            ],\n            [\n              -168.00292968749997,\n              65.73965627227945\n            ],\n            [\n              -168.00292968749997,\n              64.89558934777301\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"4","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059e9d1e4b0c8380cd48498","contributors":{"authors":[{"text":"Hopkins, D.M.","contributorId":103646,"corporation":false,"usgs":true,"family":"Hopkins","given":"D.M.","email":"","affiliations":[],"preferred":false,"id":357771,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rowland, R.W.","contributorId":36153,"corporation":false,"usgs":true,"family":"Rowland","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":357769,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Echols, R.E.","contributorId":12186,"corporation":false,"usgs":true,"family":"Echols","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":357768,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Valentine, P.

The major objectives of the study were to (1) catalog basic physical data on the recharge basins in use on Long Island, (2) measure quality and quantity of precipitation and inflow, (3) measure infiltration rates at selected recharge basins, and (4) evaluate regional effects of recharge basins on the hydrologic system of Long Island. The area of study consists of Nassau and Suffolk Counties -- about 1,370 square miles -- in eastern Long Island, N.Y. \r\n\r\nRecharge basins, numbering more than 2,100 on Long Island in 1969, are open pits in moderately to highly permeable sand and gravel deposits. These pits are used to dispose of storm runoff from residential, industrial, and commercial areas, and from highways, by infiltration of the water through the bottom and sides of the basins. \r\n\r\nThe hydrology of three recharge basins on Long Island -- Westbury, Syosset, and Deer Park basins -- was studied. The precipitation-inflow relation showed that the average percentages of precipitation flowing into each basin were roughly equivalent to the average percentages of impervious areas in the total drainage areas of the basins. Average percentages of precipitation flowing into the basins as direct runoff were 12 percent at the Westbury basin, 10 percent at the Syosset basin, and 7 percent at the Deer Park basin. Numerous open-bottomed storm-water catch basins at Syosset and Deer Park reduced the proportion of inflow to those basins, as compared with the Westbury basin, which has only a few open-bottomed catch basins. \r\n\r\nInflow hydrographs for each basin typify the usual urban runoff hydrograph -- steeply rising and falling limbs, sharp peaks, and short time bases. Unit hydrographs for the Westbury and the Syosset basins are not expected to change; however, the unit hydrograph for the Deer Park basin is expected to broaden somewhat as a result of additional future house construction within the drainage area. \r\n\r\nInfiltration rates averaged 0.9 fph (feet per hour) for 63 storms between July 1967 and May 1970 at the Westbury recharge basin, 0.8 fph for 22 storms from July 1969 to September 1970 at the Syosset recharge basin, and 0.2 fph for 24 storms from March to September 1970 at the Deer Park recharge basin. Low infiltration rates at Deer Park resulted mainly from (1) a high percentage of eroded silt, clay, and organic debris washed in from construction sites in the drainage area, which partly filled the interstices of the natural deposits, and (2) a lack of a well-developed plant-root system on the floor of the younger basin, which would have kept the soil zone more permeable. \r\n\r\nThe apparent rate of movement of storm water through the unsaturated zone below each basin averaged 5.5 fph at Westbury, 3.7 fph at Syosset, and 3.1 fph at Deer Park. The rates of movement for storms during the warm months (April through October) were slightly higher than average, probably because the recharging water was warmer than it was during the rest of the year, and therefore, was slightly less viscous.\r\n\r\nOn the average, a 1-inch rainfall resulted in a peak rise of the water table directly below each basin of 0.5 foot; a 2-inch rainfall resulted in a peak rise of about 2 feet. The mound commonly dissipated within 1 to 4 days at Westbury, 7 days to more than 15 days at Syosset, and 1 to 3 days at Deer Park, depending on the magnitude of the peak buildup. \r\n\r\nAverage annual ground-water recharge was estimated to be 6.4 acre-feet at the Westbury recharge basin, 10.3 acre-feet at the Syosset recharge basin, and 29.6 acre-feet at the Deer Park recharge basin. \r\n\r\nChemical composition of precipitation at Westbury, Syosset, and Deer Park drainage areas was similar: ","language":"ENGLISH","publisher":"U.S. Govt.
