The program accepts gridded data of the form Z(x,y), where Z is the value at the grid intersection, (x,y). Up to 10 sets of Z(x,y) data for a given grid may be drawn on the same section. The positions of the end points of the cross-section are arbitrary. A bilinear interpolation scheme is used to obtain the Z(x,y) values along the specified cross-section. \r\n\r\nThe program was designed to provide a visual aid for interpreting input and output data for two-dimensional (areal) finite-difference models used in aquifer analysis and geothermal reservoir simulation.

It is based primarily upon the historic seismic record which ranges from very incomplete before 1930 to moderately complete after 1960. Geologic data, primarily distribution of faults, have been employed only to a minor extent, because most such data have not been interpreted yet with earthquake hazard evaluation in mind.</p><p>The map provides a preliminary estimate of the relative hazard in various parts of the country. The report provides a method for evaluating the relative importance of the many parameters and assumptions in hazard analysis. The map and methods of evaluation described reflect the current state of understanding and are intended to be useful for engineering purposes in reducing the effects of earthquakes on buildings and other structures.</p><p>Studies are underway on improved methods for evaluating the relativ( earthquake hazard of different regions. Comments on this paper are invited to help guide future research and revisions of the accompanying map.</p><p>The earthquake hazard in the United States has been estimated in a variety of ways since the initial effort by Ulrich (see Roberts and Ulrich, 1950). In general, the earlier maps provided an estimate of the severity of ground shaking or damage but the frequency of occurrence of the shaking or damage was not given. Ulrich's map showed the distribution of expected damage in terms of no damage (zone 0), minor damage (zone 1), moderate damage (zone 2), and major damage (zone 3). The zones were not defined further and the frequency of occurrence of damage was not suggested. Richter (1959) and Algermissen (1969) estimated the ground motion in terms of maximum Modified Mercalli intensity. Richter used the terms \"occasional\" and \"frequent\" to characterize intensity IX shaking and Algermissen included recurrence curves for various parts of the country in the paper accompanying his map.</p><p>The first probabilistic hazard maps covering portions of the United States were by Milne and Davenport (1969a). Recently, Wiggins, Hirshberg and Bronowicki (1974) prepared a probabilistic map of maximum particle velocity and Modified Mercalli intensity for the entire United States. The maps are based on an analysis of the historical seismicity. In general, geological data were not incorporated into the development of the maps.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76416","usgsCitation":"Algermissen,

They consist primarily of limestone, dolomite, and quartz arenite deposited in a shallow north-trending miogeosyncline, which constituted a single major basin of accumulation on this shelf. \r\n\r\nThe Guilmette Formation and equivalents were deposited in shallow normal to hypersaline marine waters. The environments of deposition include: a moderate- to high-energy intertidal environment, a moderate-energy subtidal environment, a lower energy, deeper subtidal environment below effective wave base, and a high-energy environment in local shallow areas of mud mounds and bioherms. \r\n\r\nThe carbonate deposition of the Guilmette Formation and equivalents was interrupted periodically by the deposition of quartz arenites. These may represent the breaking up of the miogeosynclinal-cratonic pattern of deposition. In most areas, the Guilmette and equivalents are overlain by a thin transgressive marine quartz arenite deposit--the Cove Fort Quartzite and basal Leatham equivalent.\r\n\r\nPrevious paleontologic evidence indicated a general Middle to Late Devonian age for the Guilmette Formation. The present study narrows this range and suggests that the age of the Guilmette Formation and its equivalents is late Middle Devonian (Stringocephalus brachiopod zone) to early Late Devonian (Uppermost Palmatolepis gigas conodont zone). \r\n\r\nAvailable subsurface data suggest that the petroleum possibilities of the Guilmette Formation and equivalents in southwestern Utah are poor. Several tests have penetrated .the interval with only minor shows of oil in rocks with low porosity and permeability. Nevertheless, many outcrop samples of the same interval, appear to have excellent porosity and permeability and a strongly fetid odor,","language":"English","publisher":"U.S. Geological

The natural surface of the Earth is composed of a diversified combination of surface cover types, and geologists must understand the characteristics of surface cover types to successfully evaluate remotely-sensed data. In some areas landscape surface cover changes throughout the year, and analysis of imagery acquired at different times of year can yield additional geological information. Integration of different scales of analysis allows landscape features to be effectively interpreted. Interpretation of the static elements displayed on imagery is referred to as an image interpretation. Image interpretation is dependent upon: (1) the geologist's understanding of the fundamental aspects of image formation, and (2.) his ability to detect, delineate, and classify image radiometric data; recognize radiometric patterns; and identify landscape surface characteristics as expressed on imagery. A geologic interpretation integrates surface characteristics of the landscape with subsurface geologic relationships. Development of a geologic interpretation from imagery is dependent upon: (1) the geologist's ability to interpret geomorphic processes from their static surface expression as landscape characteristics on imagery, (2) his ability to conceptualize the dynamic processes responsible for the evolution 6f interpreted geologic relationships (his ability to develop geologic models). The integration of geologic remote-sensing techniques in subsurface analysis is illustrated by development of an exploration model for ground water in the Tucson area of Arizona, and by the development of an exploration model for mineralization in southwest Idaho.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr76402","usgsCitation":"Taranik, J.V., and Trautwein, C.M., 1976, Integration of geological remote-sensing techniques in subsurface analysis: U.S. Geological Survey Open-File Report 76-402, viii, 80 p., https://doi.org/10.3133/ofr76402.","productDescription":"viii, 80 p.","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":45142,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0402/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":150453,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0402/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49dbe4b07f02db5e0f85","contributors":{"authors":[{"text":"Taranik, James V.","contributorId":67514,"corporation":false,"usgs":true,"family":"Taranik","given":"James","email":"","middleInitial":"V.","affiliations":[],"preferred":false,"id":172425,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Trautwein, Charles M. trautwein@usgs.gov","contributorId":2861,"corporation":false,"usgs":true,"family":"Trautwein","given":"Charles","email":"trautwein@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":172424,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Glacial drift aquifers are the largest source of ground water. The surficial outwash sand and gravel is the most readily available and the most areally extensive drift aquifer, and it underlies much of the sandy soil area. Saturated thickness of the outwash is more than 80 feet (24 m) in places, and potential well yields may exceed 1,200 gal/min (76 1/s) in some areas. In about 17 percent of the area, yields of more than 300 gal/min (19 1/s) are obtainable.</p>\n<p>Recharge to the outwash aquifer occurs primarily during the spring thaw and averages about 5 inches (12.7 cm) annually. Most discharge from the aquifer appears as base flow in the Pomme de Terre River. Despite dissolved-solids concentrations ranging from 280 to 1,350 mg/1, the water is chemically suitable for irrigation.</p>\n<p>Mathematical models of a part of the aquifer were made to evaluate the effects of 20 successive years of ground-water withdrawal for three irrigation-development patterns. It was estimated that the present annual withdrawal rate of 1,410 acre-ft (1.74 hm<sup>3</sup>) would result in water-level declines of less than 3 feet (0.9 m). However, annual withdrawals of 8,450 acre-ft (10.4 hm<sup>3</sup>) would cause aquifer dewatering and decreased well yields in some places. After a new state of equilibrium was established in response to withdrawals, most of the withdrawal would be supplied by diverted base flow from the Pomme de Terre River.</p>","language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/wsp2039B","collaboration":"Prepared in cooperation with the WesMin

The magnetic map suggests that the Ice Harbor dike swarm is offset by left-lateral strike-slip displacement along the Rattlesnake-Wallula fault, a segment of the Olympic-Wallowa lineament.

In this report, we study this problem by first deriving the differential equations governing seismic wave propagation between two end points in a 3-dimensional heterogeneous and isotropic medium. We then formulate three numerical schemes to solve the two-point ray-tracing problem. In the first method, introduced originally by R. L. Wesson, the second order ray equations are reduced by the central difference approximation to a set of simultaneous non-linear equations, which are then solved by Newton's method. In the second method, the second order ray equations are reduced to a set of first order equations which are solved by using an adaptive finite difference method introduced by M. Lentini and V. Pereyra. The third method, due originally to L. Euler uses a sum to approximate the integral for the travel time which are solved directly for the minimum time path. This formulation may be shown to be equivalent to Wesson's method.</p><p>We programed Wesson's method for a 3-dimensional inhomogeneous velocity medium, and also applied Lentini and Pereyra's method for a 2-dimensional linear velocity model.

The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model, developed for this part of the study, incorporates an inflow component, a diversion-canal component, and a reservoir system component and is capable of evaluating the performance of the reservoir systemem for a variety of operating rule conditions. All model components were verified using observed reservoir input and output data for a 6-year (1967-72 water years) period.

During this time interval compressive strains were oriented roughly normal to the San Andreas fault, suggesting that the uplift produced little shear strain accumulation across this fault. On the other hand, the orientation of the anomalous shear straining is consistent with strain accumulation across northdipping range-front thrusts like the San Fernando fault. Accordingly, the horizontal and vertical crustal deformation disclosed by geodetic observation is interpreted as a short epoch of rapid strain accumulation on these frontal faults. If this interpretation is correct, thrust-type earthquakes will eventually release the accumulated strains, but the geodetic data examined here cannot be used to estimate when these events might occur. However, observation of an unusual sequence of tilts prior to 1971 on a level line lying to the north of the magnitude 6.4 San Fernando earthquake offers some promise for precursor monitoring. The data are adequately explained by a simple model of up-dip aseismic slip propagation toward the 1971 epicentral region. These observations and the simple model that accounts for them suggest a conceptually straightforward monitoring scheme to search for similar uplift and tilt precursors within the uplifted region. Such premonitory effects could be detected by a combination of frequently repeated short (30 to 70 km in length) level line measurements, precise gravity traverses, and continuously recording gravimeters sited to the north of the active frontal thrust faults. Once identified, such precursors could be closely followed in space and time, and might then provide effective warnings of impending potentially destructive earthquakes.</span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.194.4266.691","issn":"00368075","usgsCitation":"Thatcher, W., 1976, Episodic strain accumulation in Southern California: Science, v. 194, no. 4266, p. 691-695, https://doi.org/10.1126/science.194.4266.691.","productDescription":"5 p.","startPage":"691","endPage":"695","costCenters":[],"links":[{"id":221024,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Southern California","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -121.9804029819224,\n              36.30513645238112\n            ],\n            [\n              -120.96601429202806,\n              34.360346703747\n            ],\n            [\n              -119.17331019306403,\n              32.27556539094205\n            ],\n            [\n              -114.34970515576546,\n              32.86548144988561\n            ],\n            [\n              -114.08039140095518,\n              34.30260170922787\n            ],\n            [\n              -114.596289953596,\n              34.95052476022777\n            ],\n            [\n              -117.75432473596952,\n              37.47447472393604\n            ],\n            [\n              -121.9804029819224,\n              36.30513645238112\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"194","issue":"4266","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0a15e4b0c8380cd521c3","contributors":{"authors":[{"text":"Thatcher, W.","contributorId":32669,"corporation":false,"usgs":true,"family":"Thatcher","given":"W.","email":"","affiliations":[],"preferred":false,"id":360421,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The flux estimation is the result of the Surtsey data-relay experiment via Landsat-1 which was carried. out in several phases. Successful field installation and test transmissions demonstrated the feasibility of repetitive long-distance (that is, 4,800-km) data transmission and reception from a volcanic environment in Iceland via the Landsat Data Collection System. Temperature data were transmitted for a 38-day period in November and December 1972.

During deposition of the Jackson Group, conditions were similar to those existing along the modern Gulf Coast of Texas except for a less arid climate and a greater supply of volcanic sediment. Sedimentary depositional environments recognized in both the modern coast and the Jackson rocks, in order from sea toward land, are: shoreface, beach, lagoon and bay, and paludal. Sediment deposited in these environments in places is interbedded with or transected by fluvial sediment. Both uranium and petroleum are found in the shoreface, beach, and fluvial facies. These facies are characterized by permeable well-sorted sandstone, which is commonly overlain and underlain by less permeable mudstone. A typical vertical sequence in ascending order through a unit containing a beach sandstone facies is (1) lagoonal or paludal clay stone and siltstone, (2) crossbedded fine-grained beach sandstone which contains <i>Ophiomorpha</i> burrows and, which, in places, is locally interbedded with lacustrine or lagoonal mudstone, (3) weakly laminated beach sandstone which contains root impressions at the top and <i>Ophiomorpha</i>, and (4) lagoonal or paludal claystone and siltstone. Gulfward, the beach sandstone apparently grades into highly burrowed, generally finer grained, more poorly sorted, less porous shoreface rocks. The beach facies may include barrier island beaches and mainland beaches, some of which were probably cheniers. Beach facies sandstone units extend many miles along the depositional strike, which nearly parallels the present outcrop strike, but extend only a mile or two (2-3 km) normal to the depositional strike into the subsurface. Recognition of the various facies in outcrops and drill holes is necessary for determination of true stratigraphic relations and for aid in exploration for beach and fluvial sandstone favorable for uranium and petroleum accumulations.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Dickinson, K.A., 1976, Sedimentary depositional environments of uranium and petroleum host rocks of the Jackson Group, south Texas: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 615-629.","productDescription":"15 p.","startPage":"615","endPage":"629","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307454,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307453,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf","text":"Report","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Texas","county":"Karnes County, McMullen County, Duval County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -100,\n              31.541089879585808\n            ],\n            [\n              -94,\n              31.541089879585808\n            ],\n            [\n              -94,\n              29.649868677972304\n            ],\n            [\n              -94.482421875,\n              29.401319510041485\n            ],\n            [\n              -95.361328125,\n              28.844673680771795\n            ],\n            [\n              -96.240234375,\n              28.478348692223165\n            ],\n            [\n              -96.65771484375,\n              28.07198030177986\n            ],\n            [\n              -97.119140625,\n              27.254629577800088\n            ],\n            [\n              -97.22900390625,\n              26.43122806450644\n            ],\n            [\n              -96.9873046875,\n              25.859223554761407\n            ],\n            [\n              -97.42675781249999,\n              25.859223554761407\n            ],\n            [\n              -98.19580078125,\n              26.03704188651584\n            ],\n            [\n              -99.03076171875,\n              26.2145910237943\n            ],\n            [\n              -99.5361328125,\n              27.00040800352175\n            ],\n            [\n              -99.64599609375,\n              27.625140335093324\n            ],\n            [\n              -100,\n              28.130127737874005\n            ],\n            [\n              -100,\n              31.541089879585808\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91bee4b0518e354dd1b9","contributors":{"authors":[{"text":"Dickinson, Kendell A.","contributorId":55430,"corporation":false,"usgs":true,"family":"Dickinson","given":"Kendell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":569861,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The sedimentary sequence consists of moderately deformed and little-metamorphosed conglomerate, sandstone, mudstone, claystone, chert, and limestone. The melange consists of a chaotic mechanical mixture of rocks identical to those of the sedimentary sequence and their metamorphic equivalents, such as schist, phyllite, quartzite, and marble. In addition, it contains a large proportion of quartz porphyry and smaller amounts of granite, basalt, gabbro, peridotite, pyroxenite, and serpentinite. The sedimentary sequence is at least partly of Early Cretaceous age and the melange is of Early Cretaceous to very early Paleocene age. They are overlain unconformably by Eocene rocks. The presence in the melange of blocks of quartz porphyry and granite is not easily reconcilable with current plate tectonic concepts in which the sites of formation of melange and plutonic rocks should be hundreds of kilometres apart.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Ketner, K.B., , K., Modjo, S., Naeser, C.W., Obradovich, J.D., Robinson, K., Suptandar, T., and , W., 1976, Pre-Eocene rocks of Java, Indonesia: Journal of Research of the U.S. Geological Survey, v. 4, no. 5, p. 605-614.","productDescription":"10 p.","startPage":"605","endPage":"614","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307447,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307444,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1976/vol4issue5/report.pdf","text":"Report","size":"29.18 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"Indonesia","otherGeospatial":"Java","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              106.962890625,\n              -8.49410453755187\n            ],\n            [\n              106.962890625,\n              -6.0968598188879355\n            ],\n            [\n              112.69775390625,\n              -6.0968598188879355\n            ],\n            [\n              112.69775390625,\n              -8.49410453755187\n            ],\n            [\n              106.962890625,\n              -8.49410453755187\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"4","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"55dd91bde4b0518e354dd1aa","contributors":{"authors":[{"text":"Ketner, Keith B.","contributorId":957,"corporation":false,"usgs":true,"family":"Ketner","given":"Keith","email":"","middleInitial":"B.","affiliations":[],"preferred":true,"id":569841,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":" Kastowo","contributorId":147008,"corporation":false,"usgs":false,"given":"Kastowo","email":"","affiliations":[],"preferred":false,"id":569842,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Modjo, Subroto","contributorId":147009,"corporation":false,"usgs":false,"family":"Modjo","given":"Subroto","email":"","affiliations":[],"preferred":false,"id":569843,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Naeser, C.
