This issue of the Bulletin of the Seismological Laboratory summarizes the determination of epicenters for earthquakes located in the western Great Basin, Nevada and eastern California, for the period 1975-1979. The Laboratory attempts to identify and locate all earthquakes with ML greater than about 2.5 in this region. Quality of locations is best for events located in areas with dense seismic coverage; events well outside the network (aftershocks of NTS explosions, etc.) may be mislocated by several tens of kilometers.

Most of the resources occur in veins that have an average grade of between 0.1 and 2.0 percent Th02. More than 200 thorium-bearing veins have been mapped in this district (Staatz, 1979, p. A34).
The Lemhi Pass thorium district lies astride the Continental Divide in the east-central part of the Beaverhead Mountains along the Idaho-Montana State line. Although the area in which thorium veins are found covers more than 150 square miles, the drilling project was confined to three veins in the northwestern part of this district on the Montana side of the Continental Divide (fig. 1). An unimproved dirt road that crosses the Continental Divide at Lemhi Pass furnishes access to the drilling area. This road connects Idaho State Highway 28 at Tendoy, Idaho, 13 miles west of Lemhi Pass, with Interstate Highway 15 at the Clark Canyon reservoir/dam, 31.5 miles east of Lemhi Pass. Salmon, Idaho, the principal town to the west, is 19 miles northwest of Tendoy; and Dillon, Mont., the principal town to the east, is 18 miles northeast of Clark Canyon Reservoir.
The drilling project was proposed by the Department of Energy headquarters personnel in Washington, D.C., during the spring of 1978. The purpose of the project was to demonstrate downward extension of the veins. Drilling was proposed to indicate whether several veins had a depth of 500 feet or more.
Little exploration has been carried out on thorium veins. The lack of a ready market for thorium has resulted in little economic incentive for exploration. Most veins in this district are covered by 50 feet of soil.

The interval tested (1,050 to 1,070 feet below sea level) is in a calcarenite that is equivalent to the Ocala Limestone (late Eocene) of onshore Florida and South Georgia. At this site the Ocala forms the highly productive Tertiary limestone aquifer system of the southeastern United States. Pressure-head measurements indicate an equivalent freshwater head of 24 to 29 feet above sea level. These pressure-head measurements and an earlier one made in the nearby JOIDES J-1 hole are the only hydraulic head determinations to date in the offshore extensions of any of the aquifers underlying the Atlantic coastal plain.
A drill-stem test recovered water samples containing about 7,000 milligrams per liter chloride. However, seawater used in the drilling process apparently contaminated the samples and the formation water is considered slightly fresher.
The head and salinity data from the Tenneco well suggest that the sampled interval lies in the transition zone between fresh and seawater in the limestone aquifer. These data, when viewed with similar data from JOIDES J-1, show the transition zone to slope very slightly landward. Heads at both wells are compatible with the onshore flow system as it existed prior to development.

Data obtained from the network from October 1976 through September 1977, as well as rainfall and pumpage records, are presented and discussed. Below-normal rainfall caused the water table and potentiometric surface of the Floridan aquifer in Eldridge-Wilde well field to recover 2 feet less in September 1977 than in the previous September. Water levels in East Lake Road will field were approximately the same in September of both years. The Southwest Florida Water Management District has established regulatory water-level and water-quality limits in several observation wells. Water levels did not drop below regulatory limits during the year. Water from two deep wells west of Eldridge-Wilde well field exceeded the regulatory limits for chloride concentrations. The position of the 250 milligram per liter chloride line is shown in cross section in the vicinity of Eldridge-Wilde well field in September 1977. Network modifications are proposed that would result in a more comprehensive knowledge of the hydrologic system.

VERRILL as part of a continuing regional study of the Massachusetts offshore area to determine the suitability and potential environmental effect of ocean dumping of large volumes of harbor dredge-spoil material.
Specifically, as part of a proposed Federal Harbor improvement and maintenance dredging of Fall River and Mt. Hope Bay, Mass. under the jurisdiction of the Army Corps of Engineers, the disposal of the resultant dredge spoil is planned for an ocean dump site located in eastern Rhode Island Sound. The proposed site is also under consideration as a \"regional\" disposal grounds to be utilized by State and private organizations performing dredging work authorized by the Corps.
The data were obtained by using a Klein Side Scan Towfish* (sonar frequency, 100 kHz; pulse length, 0.1 msec). Signal returns from the starboard and port scans were automatically tuned, texture-enhanced, and printed centerout on 2 channels of a 3-channel Klein* wet-paper graphic recorder. Scan ranges of 75 m and 150 m were used. For comparison of graphic display, incoming signals from the starboard scan were also recorded on the third channel using a manual (nonautomatic) tuning mode. Navigational control was provided by Loran -C (positional accuracy within 0.2 km). Positional information was logged at 15-minute intervals and at major course changes.
The original records may be examined at the Data Library, U.S. Geological Survey, Woods Hole, MA 02543. Microfilm copies of the data are available for purchase from the National Geophysical and Solar-Terrestrial Data Center (NGSDC), Boulder, CO 80302.

The area described in this report includes about 3,050 square miles in west-central Maine. Location of the area within the State is shown in figure 1, and a sketch map identifying the 15-minute topographic quadrangles for the study area is given in figure 2. The western boundary is the New Hampshire State line, and the eastern boundary is the Franklin-Somerset County line.
In 1976 the U.S. Geological Survey undertook a program to sample the eastern United States Shelf for stratigraphic information by drilling a set of core holes. Results of this Atlantic Margin Coring Program (AMCOR) have been reported by Hathaway and others. Sites were chosen from seismic-reflection data and were reviewed by a safety panel to minimize the risk of penetrating any hydrocarbon accumulation which might lead to environmental contamination.
The M-V-L'OLONNOIS, the service ship for the drilling operation, was fitted with seismic-reflection profiling equipment (listed below), to run seismic-reflection profiles before drilling began on each hole. This provided additional assurance that no closed structures would be penetrated and allowed minor adjustment with the site selection. A total of 491 km of high-resolution seismic profiles was collected on 22 sites.
Equipment used (specifics for each site noted on records):
Bolt Air Guns 1-40 cubic inch chambers
EPC Recorder
Teledyne Minisparker (last two sites)
Navigation used two Internav 101 Loran-C receivers.

Hydrogeologic data were collected in selected coal areas of east-central Montana to provide a basis for evaluating the effects of future coal development on the groundwater resources. Inventory records for 916 domestic, stock, public supply, commercial, and test wells are tabulated in the report; the data were collected principally from 1975 through 1976. The locations of the wells are shown on a map at a scale of 1:250,000. Lithologic logs are also included for 149 wells. Chemical analyses of water samples from selected wells consist of 167 samples analyzed for major cations and anions and 24 samples analyzed for miscellaneous constituents.

In 1962, a plan was developed for a proposed project to reduce the threat of floods. In 1976, a study of the hydrology of the basin was proposed to help evaluate this plan and to serve as a basis for its modification; the study was conducted from October 1976 through September 1977.
Jumper Creek Canal drains a basin of 83 square miles in which the average yearly rainfall is about 53 inches. Average runoff from the upper 40 square miles of the basin is estimated to be about 30 cubic feet per second or 10 inches per year. Evapotranspiration is estimated to be about 37 inches per year. Variation in runoff from Jumper Creek Canal is much less than that from most other basins in west-central Florida because of large storage capacity in the basin both on the surface and in the ground.
Limestone in Jumper Creek Canal basin is covered by a veneer of sand and clays which ranges in thickness from 0 to 10 feet. The study indicates that most of the base flow in the canal enters the canal east of the site of the proposed water-control structure number 5 and that the discharge in the canal at State Highway 475 has been about the same relative to rainfall in the basin since 1963 whether the base flow was derived entirely from natural inseepage or partly from mine pumpage.
The study shows that implementation of the proposed project will result in (1) a decrease in surface outflow, (2) an increase in subsurface outflow, (3) a rise in the potentiometric surface of the Floridan aquifer near the canal and (4) a tendency to increase evapotranspiration and the magnitude of floods in the basin.

The present water supplies for these communities are not always adequate to meet current demands. The U.S. Geological Survey made a water-supply assessment of the Laramie-Fox Hills aquifer for the U.S. Bureau of Reclamation, which is investigating and evaluating alternative sources of water for the communities. Recharge to the aquifer is mostly in the western and southwestern parts of the study area. Groundwater movement is generally from the southwest to northeast. Groundwater discharge in the study area is primarily by pumping wells. Since 1961, this pumping has caused water-level declines of about 250 to 300 feet from Broomfield to east of Erie, Colorado. Generally, water levels in other parts of the area have remained the same. The aggregate sand thickness determined from well logs ranges from 42 to 360 feet and the mean thickness is 229 feet. The volume of groundwater in storage in the study area is about 5 million acre-feet. Reported yields from 93 wells ranged from 1 to 90 gallons per minute and averaged 22 gallons per minute. Well yields tended to be larger in the areas where aggregate sand thickness is the greatest. The water generally changes from a sodium calcium bicarbonate type to a sodium calcium sulfate type as it moves through the aquifer away from the recharge areas. The maximum limit established by the U.S. Environmental Protection Agency for nitrite plus nitrate in public-water supplies was exceeded in water from three wells, the maximum limit for fluoride was exceeded in water from two wells, and the maximum limit for selenium was exceeded in water from three wells.

The quality-of-water data were collected during a period of generally low streamflow and seasonally high air temperatures. These data show that the quality of water in Hobolochitto Creek was generally good. The dissolved-solids concentrations were less than 50 milligrams per liter, and the concentrations of nitrogen and phosphorus species were low. The 5-day biochemical oxygen demand generally was minimal, and dissolved-oxygen concentrations were at levels that could support aquatic life. Several water samples contained high fecal bacteria densities and there was evidence of the presence of wastes of human origin, particularly at the downstream sites on Hobolochitto Creek. It was determined from a time-of-travel study that the rate of solute travel is very slow at low streamflow. A peak dye concentration traveled through a 3.7-mile reach of Hobolochitto Creek in 23.5 hours.

The surface faulting was discontinuous and of small displacement. The main rupture within the Greenville fault zone trended about N.38°W. It was at least 4.2 km long and may have extended southward to Interstate Highway 580, giving a possible length of 6.2 km; both of these lengths included more gaps than observed surface rupture. Maximum displacements measured by us were about 25 mm of right slip (including afterslip through 28 January); vertical components of as much as 50 mm were seen locally, but these included gravity effects of unknown amount. The main break within the Greenville fault zones is very close to a fault strand mapped by Herd (1977, and unpublished data). A subsidiary break within the Greenville fault zone was about 0.5 km. long, had a general trend of N.46°W., and lay 0.12 to 0.25 km east of the main break. It was characterized by extension of as much as 40 mm and right slip of as much as 20 mm. This break was no more than 25 m from a fault mapped by Herd (unpublished data). Another break within the Greenville fault zone lay about 0.3 km southwest of the projection of the main break and trended about N33°W. It was at least 0.3 km long and showed mostly extension, but at several places a right-lateral component (up to 5 mm) was seen. This break was 80 to 100 m from a strand of the Greenville fault mapped by Herd (1977). Extensional fractures within the Greenville fault zone on the frontage roads north and south of Interstate Highway 580 may be related to regional extension or other processes, but do not seem to have resulted from faulting of the usual kind. One exception in this group is a fracture at the east side of Livermore valley which showed progressive increase in right-lateral displacement in February and March, 1980, and is directly on the projection of a fault in the Greenville fault zone mapped by Herd (1977). A group of more than 20 extensional fractures in Laughlin Road 1 km north of Interstate 580 probably are related to small tectonic displacements on faults in the Greenville fault zone. They are adjacent and parallel to two faults mapped by Herd (1977), are diagonal to the road, and most of them developed between 25 and 29 January, a period that included the Ms 5.2 shock of 26 January. Observations at two locations indicate tectonic displacement on the Las Positas fault zone as mapped by Herd (1977). At Vasco Road a prominent break on a strand of the fault showed about 0.5 mm of left-lateral strike slip on 7 February. An alinement array across this and other fractures at the locality indicates about 6 mm of left-lateral displacement occurred between 21 February and 26 March. On Tesla Road several right-stepping fractures, one of which showed 1.5 mm of left-lateral strike slip, lie on or close tp previously mapped strands of the Las Positas fault zone. The evidence at these two localities indicates that tectonic surface displacement occurred along at least 1.1 km of the Las Positas fault zone.","language":"English","publisher":"U.S. Geological Survey,","publisherLocation":"Reston, VA","doi":"10.3133/ofr80523","collaboration":"In cooperation with the U.S. Nuclear Regulatory Commission","usgsCitation":"Bonilla, M.G., Lienkaemper, J.J., and Tinsley, J.C., 1980, Surface faulting near Livermore, California, associated with the January 1980 earthquakes: U.S. Geological Survey Open-File Report 80-523, Report: 32 p.; Plate 1: 15.18 x 32.76 inches, https://doi.org/10.3133/ofr80523.","productDescription":"Report: 32 p.; Plate 1: 15.18 x 32.76 inches","onlineOnly":"Y","temporalStart":"1980-01-24","temporalEnd":"1980-01-26","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":420923,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_11678.htm","linkFileType":{"id":5,"text":"html"}},{"id":115841,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1980/0523/","linkFileType":{"id":5,"text":"html"}},{"id":254662,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_80_523.gif"}],"scale":"24000","datum":"Mean Sea Level","country":"United States","state":"California","city":"Livermore","otherGeospatial":"Las Positas Valley","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -121.75,\n 37.75\n ],\n [\n -121.75,\n 37.65\n ],\n [\n -121.657,\n 37.65\n ],\n [\n -121.657,\n 37.75\n ],\n [\n -121.75,\n 37.75\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b00e4b07f02db6982a3","contributors":{"authors":[{"text":"Bonilla, Manuel G.","contributorId":74384,"corporation":false,"usgs":true,"family":"Bonilla","given":"Manuel","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":188410,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lienkaemper, James J. 0000-0002-7578-7042 jlienk@usgs.gov","orcid":"https://orcid.org/0000-0002-7578-7042","contributorId":1941,"corporation":false,"usgs":true,"family":"Lienkaemper","given":"James","email":"jlienk@usgs.gov","middleInitial":"J.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":188408,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tinsley, J.

The lakes and reservoirs sampled range from large reservoirs in the eastern part of the State to smaller natural lakes in the higher western parts of the Colorado Plateaus. The smallest body of water sampled was Anderson Reservoir No. 1 with a surface area of 47 acres in Mesa County, and the largest was Najajo Reservoir with a surface area of 15,600 acres in Archuleta County. The report includes physical, chemical, and biological water-quality data collected as a part of each lake or reservoir reconnaissance. Also included are data on drainage area, water-surface altitude, surface area,depth, storage capacity, and principal uses, obtained from various governmental agencies or the owner or regulating agency of each lake or reservoir. A subjective evaluation of the trophic (enrichment) state is presented based on nutrient and phytoplankton concentrations and the dissolved-oxygen distribution. In addition, a numerical trophic-state index, based on Secchi-disk transparency (a measure of light penetration) is reported, to show trophic comparisons between lakes and reservoirs.

Currently (1977) about 47,300 acres of land are irrigated with groundwater. Groundwater levels are declining in some areas as much as 4 feet per year. The investigation was made to provide State water administrators with data on water-level changes resulting from present (1977) groundwater withdrawals and to provide a means of predicting the future effect of groundwater development. A digital model was developed of the hydrologic system in the post-Cretaceous rocks. The ability of the model to simulate the hydrologic system was determined by comparing the water-level changes measured at 37 observation wells located in areas of irrigation pumping with the water-level changes calculated by the model for 1971-77. Comparison of the measured and calculated changes showed agreement with a root-mean-square deviation of + or - 3.6 feet with 8 feet as the maximum deviation. It is concluded that the model adequately simulates present hydrologic conditions in the post-Cretaceous rocks and may be used to predict the effect of applied stress to the system.

The area surveyed is located in the western San Juan Mountains near Lake City, Colorado. The general area covered is between 37°45' and 38° latitude north and 107°15' and 107°35' longitude west. The survey flying was confined to nine valleys which surround the Lake City caldera. Four blocks were surveyed from October 22 to October 27, 1979 for a total of 535 line - kilometers. The survey was flown as part of a mineral appraisal study conducted in cooperation with Bureau of Land Management (BLM). The survey was done to detect massive mineralization, mainly copper, and to locate conductive faults that may be suitable sites for uranium mineralization.
To be useful, airborne electromagnetic measurements must be made within a few hundred feet of the surface. The area that was flown is so rugged that a helicopter rather than a fixed-wing aircraft was used.
Fraser and Dvorak summarize the data of the survey areas as follows: in the east and south, the ground resistivities varied over a broad range—, from 20 to 1000 ohm-m. The western and northern parts of the area were characterized by resistivities mostly in the 300 to 1000 ohm-m range. Several weak to moderate EM anomalies were located that may warrant ground follow-up work.

These dates, combined with fossil identifications and measured stratigraphic sections, provide significant insights into the history of glaciation, climatic change, and related events of late Quaternary time in the north-central Brooks Range.
Two dates from Tulunga Valley show that peat-forming intervals during the middle Wisconsin and during an earlier period were terminated by episodes of loess accretion that probably correspond to glaciations in the Brooks Range.
The Anayaknaurak Bluff exposure in Anaktuvuk Valley contains a weathered till of the Banded Mountain (Itkillik I) glaciation overlain by unweathered outwash gravel of Antler Valley (Itkillik II) age. Radiocarbon dates from finer alluvium above the outwash indicate that a subsequent glacial readvance north of the range front occurred shortly after 13,000 yr B.P. This event was synchronous with a major glacial readvance that culminated between about 12,900 and 12,700 yr B.P. farther east in the Atigun and Sagavanirktok Valleys.
Additional dates from Anaktuvuk Valley show that glacier ice had retreated from the Antler Valley end-moraine complex by 10,600 yr B.P. The elongate basin that formed behind the moraine dam was being filled by alluvium at this time, and filling continued as late as 6200 yr B.P. near the range front. A possible climatic reversal during this interval is suggested by dates from Anaktuvuk Valley and from Toolik Valley farther east, which show peat formation between about 9500 and 8200 yr B.P. followed by solifluction and fan-building.
Soil test pits and other excavations near Anaktuvuk Pass show that the pass was deglaciated some time prior to 7250 yr B.P., and was suitable for human habitation by at least 6500 yr B.P. Dated buried peat suggests a change to more severe frost climate sometime after about 4750 yr B.P.
Other dates from the Chandler Lake quadrangle bear mainly on formation of low (generally 2.5 to 6 m) river terraces during intervals of renewed glaciation at valley heads during the late Holocene. Neoglaciation in the north-central Brooks Range evidently began about 3500 yr B.P., or at least was perceptible by this time as increased loess influx to sites north of the range front. Stream alluviation was in progress 2800-2700 yr B.P. at sites near Anaktuvuk Pass, and continued until sometime after 2000 yr B.P. Final phases of alluviation began about 1200 and 450 yr B.P. Independent dating of cirque-glacier advances by lichenometry supports the alluvial chronology and suggests that alluviation was controlled largely by increased sediment yield to streams during times of cirque-glacier expansion and increased rock-glacier activity.

The hydrologic budget for this period showed a perennial yield of about 9,800 acre-feet per year and an annual ground-water discharge of about 11,400 acre-feet per year, comprising net pumpage of 7,100 acre-feet, phreatophyte evapotranspiration of 3,000 acre-feet, and base streamflow of 1 ,300 acre-feet. The base flow in San Antonio Creek could diminish to zero when net pumpage reaches 13,500 acre-feet per year. The environmentally sensitive marshland area of Barka Slough may then become stressed as water normally lost through evapotranspiration is captured by pumpage. The aquifer consists of alluvial valley fill that ranges in thickness from 0 to 3,500 feet. Ground water moves seaward from recharge areas along mountain fronts to a consolidated rock barrier about 5 miles east of the Pacific coast. Upwelling of ground water just east of the barrier has resulted in the 550-acre Barka Slough. Transmissivity of the aquifer ranges from 2,600 to 34,000 feet squared per day, with the lowest values occurring in the central part of the valley where the aquifer is thickest but probably finer grained. The salinity problems are increasing in the agricultural parts of the valley, which is east of the barrier. West of the barrier, stream and ground-water quality is poor, owing to seepage of saline water from the marine shale that underlies the area at shallow depths. A proposed basinwide monitoring program includes 17 water-level sites, 12 water-quality sampling sites, 3 streamflow measuring sites, and periodic infrared aerial photography of Barka Slough. A computer model of the ground-water flow system could be developed to assess the impact of various water-management alternatives.

During that time, there have been four Federal lease sales: in 1966, 1968, 1975 (Sale 35), and 1979 (Sale 48). Oil and gas production from three leases has been going on since 1968. It peaked in 1971 and now averages around 31,400 barrels of oil and 15.4 million cubic feet of gas per day. Discoveries on areas leased in the 1968 and 1975 sales have led to plans for eight new platforms to begin production in the early 1980's. Five platforms are in the eastern end of Santa Barbara Channel, one is in the western Channel, and two are in San Pedro Bay, south of Long Beach. Three rigs are doing exploratory drilling in the Region.
\nThe most recent estimates by the U.S. Geological Survey of remaining reserves for all identified fields in the Southern California Region are 695 million barrels of oil and 1,575 billion cubic feet of gas (January 1979). The USGS has also made risked estimates of economically recoverable oil and gas resources for all the leased tracts in the Region (March 1980). These risked estimates of economically recoverable resources are 394 billion barrels of oil and 1,295 billion cubic feet of gas. The USGS estimates of undiscovered recoverable resources for the entire Southern California OCS Region (January 1980) are 3,200 million barrels of oil and 3,400 billion cubic feet of gas.
\nBecause of the long history of oil and gas production in Southern California from wells onshore and in State waters, there are many existing facilities for the transportation, processing, and refining of oil and gas. Some of the expected new OCS production can be accommodated in these facilities. Four new onshore projects will be required. Two of these are under construction: (1) a 9.6-km (6-mi) onshore oil pipeline (capacity: 60,000 bpd) between Carpinteria (Santa Barbara County) and the existing Mobil-Rincon separation and treatment facility (Ventura County), and (2) a small supply base and dock (upgrade of existing facility) and a 0.4-hectare (1-acre) crude oil distribution facility in Long Beach (Los Angeles County), connected to landfall by a 3-km (1.8-mi) onshore pipeline. The two other facilities are awaiting permit approval: (1) a gas treatment plant at Las Flores Canyon (Santa Barbara County) and (2) a separation and treatment plant at Mandalay Beach (Ventura County) with 4 km (2.5 mi) of onshore pipeline on the same right-of-way from landfall to the plant and from the plant to an existing gas transmission line.
