The deepest instrument is at a depth of 186 meters, two meters below the top of the Franciscan bedrock. Earthquake data from regional distances (29 km ≤ Δ ≤ 485 km) over a wide range of azimuths are compared with the predictions of a simple plane-layered model with material properties independently determined. Spectral ratios between the surface and bedrock computed for the one horizontal component of motion that was analyzed agree rather well with the model predictions; the model predicts the frequencies of the first three peaks within 10 percent in most cases and the height of the peaks within 50 percent in most cases. Surface time histories computed from the theoretical model predict the time variations of amplitude and frequency content reasonably well, but correlations of individual cycles cannot be made between observed and predicted traces.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr76296","collaboration":"In cooperation with the Division of Reactor Research and Development, U.S. Atomic Energy Commission","usgsCitation":"Joyner, W.B., Warrick, R.E., and Oliver, A.A., 1976, Analysis of seismograms from a downhole array in sediments near San Francisco Bay: U.S. Geological Survey Open-File Report 76-296, 36 p.; Appendix; Tables; Figures, https://doi.org/10.3133/ofr76296.","productDescription":"36 p.; Appendix; Tables; Figures","onlineOnly":"Y","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":116762,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_76_296.gif"},{"id":110890,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1976/0296/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","city":"San Francisco","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db680258","contributors":{"authors":[{"text":"Joyner, William B.","contributorId":39786,"corporation":false,"usgs":true,"family":"Joyner","given":"William","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":169370,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Warrick, Richard E.","contributorId":56228,"corporation":false,"usgs":true,"family":"Warrick","given":"Richard","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":169371,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Oliver, Adolph A.

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.

Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings and pseudomatrix. Multiple deformation and deep burial of the older Tertiary sequence--the Orca Group, the shale of Haydon Peak, and the Kulthieth and Tokun Formations--caused extensive alteration and grain interpenetration, resulting in low porosity values. Less intense deformation and intermediate depth of burial of the younger Tertiary sequence--the Katalla, Poul Creek, Redwood, and Yakataga Formations--has resulted in a greater range in textural properties. Most sandstone samples in the younger Tertiary sequence are poorly sorted, tightly packed, and have strongly appressed framework grains, but some are less tightly packed and contain less matrix. Soft and mineralogically unstable framework grains have undergone considerable alteration, reducing pore space even in the youngest rocks. \r\n\r\nMeasurements of porosity, permeability, grain density, and sonic velocity of outcrop samples of the younger Tertiary sequence indicate a modest up-section improvement in sandstone reservoir characteristics. Nonetheless porosity and permeability values typically are below 16 percent and 15 millidarcies respectively and grain densities are consistently high, about 2.7 gm/cc. Low permeability and porosity values, and high grain densities and sonic velocities appear to be typical of most outcrop areas throughout the onshore Gulf of Alaska Tertiary Province.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76198","usgsCitation":"Winkler, G., McLean, H., and Plafker, G., 1976, Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska: U.S. Geological Survey Open-File Report 76-198, iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS), https://doi.org/10.3133/ofr76198.","productDescription":"iii, 48 leaves :ill., map ;27 cm.; (51 p., 6 sheets - PGS)","costCenters":[],"links":[{"id":150179,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0198/report-thumb.jpg"},{"id":45597,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0198/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683737","contributors":{"authors":[{"text":"Winkler, Gary R.","contributorId":75513,"corporation":false,"usgs":true,"family":"Winkler","given":"Gary R.","affiliations":[],"preferred":false,"id":173125,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McLean, Hugh","contributorId":73977,"corporation":false,"usgs":true,"family":"McLean","given":"Hugh","affiliations":[],"preferred":false,"id":173124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plafker, George","contributorId":3920,"corporation":false,"usgs":false,"family":"Plafker","given":"George","email":"","affiliations":[],"preferred":false,"id":173123,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

The principal deposit is the Wyodak-Anderson coal bed. The bed is 50-100 feet (15-30 meters) thick over large areas, lies less than 200 feet (60 meters) deep in a north-south trending strip nearly 100 miles (161 kilometers) long and 2-3 miles (3-5 kilometers) wide, and contains an estimated 15 billion tons (13.6 billion metric tons) of sub-bituminous, low-sulfur coal that is presently considered to be accessible to surface mining. Extensive mining of this deposit has the potential for causing a variety of environmental impacts and has been a matter of much public concern and debate in recent years. \r\n\r\nAn integrated program of geologic, hydrologic, geochemical, and related studies by the U.S. Geological Survey in central Campbell County provides basic information about the land and its resources, including (1) characteristics of the landscape, (2) properties of rocks and surface materials, (3) depth and thickness of coal, (4) streamflow, (5) depth to ground water, (6) quality of ground water, (7) sediment yield, (8) concentrations of trace elements in soils, rocks, coal, vegetation, and water, and (9) current land use. The data are used to analyze and predict some of the potential environmental effects of surface mining, such as the extent of land disturbance, nature and degree of landscape modification, and disruption of surface-water and ground-water systems. Advance knowledge and understanding of these and other problems are useful in the planning and regulation of future leasing, mining, reclamation, and related activities.","language":"ENGLISH","publisher":"U.S. Dept. of Interior, Geological Survey : distributed by Branch of Distribution, U.S. Geological Survey,","doi":"10.3133/cir743","usgsCitation":"Keefer, W.R., and Hadley, R.F., 1976, Land and natural resource information and some potential environmental effects of surface mining of coal in the Gillette area, Wyoming: U.S. Geological Survey Circular 743, vi, 27 p. :ill., maps ;26 cm. , https://doi.org/10.3133/cir743.","productDescription":"vi, 27 p. :ill., maps ;26 cm.

Measurements of magnetic properties of samples collected along valley margins or from drill holes indicate that the anomaly-producing rocks are mostly Tertiary volcanic flows in Nevada and mostly Cretaceous-Tertiary intrusives in southern New Mexico. Aeromagnetic data were compiled as both observed and residual anomalies from surveys at various flight-line spacings and intervals from ground surface. Theoretical anomalies from known models were analyzed to recover data on depth, width, and magnetization of models and thereby establish reliability of methods used by certain investigators. These methods were then applied to measured anomalies to obtain information about the igneous rock structures that are buried beneath nonmagnetic valley alluvium. Recommendations made for future valley studies include aeromagnetic surveys flown 150 m above ground surface and at 800 m spacing; measurement of magnetic properties from outcrop samples, drill-core samples, and magnetometer logging of uncased drill holes; and use of the interpretation from gravity surveys in the same area.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, Geological Survey,","doi":"10.3133/ofr76440","usgsCitation":"Bath, G.D., 1976, Interpretation of magnetic surveys in intermontane valleys of Nevada and southern New Mexico: U.S. Geological Survey Open-File Report 76-440, iii, 37 p. :ill. ;28 cm., https://doi.org/10.3133/ofr76440.","productDescription":"iii, 37 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":149885,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1976/0440/report-thumb.jpg"},{"id":46420,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1976/0440/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66d37d","contributors":{"authors":[{"text":"Bath, G.

Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet (61 metres). A conceptual model of water quality provides three potential sources for water that is relatively high in dissolved solids: brine from the Tularosa Basin to the east, slightly saline water beneath the subjacent aquatard, and very slightly saline water from the less permeable units within the aquifer itself. Management of the well field to minimize drawdown and spread the cone of depression would minimize the rate of water-quality deterioration. A well designed monitoring network may provide advance warning of severe or rapid water-quality deterioration..

Program VECTOR computes the difference vector of a tilt event and displays the sequence of events as a head-to-tail vector plot. Program ONSTSP 1) requires two component digitized tilt data as input, 2) scales and plots the data, and 3) computes and displays the amplitude, azimuth, and normalized derivative of the tilt amplitude.

By 1850 A.D. the tidal marshes of the estuary, including those of the Sacramento - San Joaquin Delta, covered an area nearly twice as large as the area of open water. Nearly 95 percent of these marshes have been diked or filled during the past 125 years. Species distributions along leveled transects at six tidal marshes indicate that elevation and water salinity are the principal ecological factors that-control the distribution of seed plants in the remaining natural tidal marshes of the northern San Francisco Bay estuary. Marsh surfaces situated near mean tide level are populated by robust monocotyledons (e.g., Spartina foliosa, Scirpus californicus), whereas surfaces situated near high-tide levels support dicotyledons and a few small monocotyledonous species (e.g., Salicornia virginica, Distichlis spicata). Marshes near the seaward end of the estuary are typically occupied by 10-15 salt-tolerant species (e.g., Spartina foliosa, Salicornia virginica), whereas marshes at the riverward end of the estuary are inhabited by as many as 30 species, most of which are known to tolerate moderate or small amounts of salt (e.g., Scirpus spp., Phragmites communis, Typha latifolia).</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr76389","usgsCitation":"Atwater, B.F., and Hedel, C.W., 1976, Distribution of seed plants with respect to tide levels and water salinity in the natural tidal marshes of the northern San Francisco Bay Estuary, California: U.S. Geological Survey Open-File Report 76-389, 1 v.

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,

Up until now, \nplotting was done using card decks processed by computer with tapes plotted \nby a Gerber plotter and more recently a CRT using a batch mode. Lack of a \nuniform format for sample identification was not a great impediment. With \nincrease in the size of the bank, hand sorting is becoming prohibitive and ·plans are underway to put the bank into a uniform format on DISK with a card \nbackup so that it may be accessed by use of IRIS on the DECK 10 computer at the \nU.S.G.S. facility in Denver.

Major sources of ground water are the Gosport Sand and Lisbon Formation undifferentiated, the Miocene Series undifferentiated, and alluvium and low terrace deposits. The Miocene, the most productive source of ground water, will yield 0.5 to 1.0 mgd (million gallons per day) per well and is a potential source of larger supplies in most of the county. The quantity of potable water available is governed largely by geologic structures. Average flows of the Tombigbee and Mobile Rivers in the southeast corner of the county are 18,200 and 39,400 mgd. Average runoff originating in the county is about 1,100 mgd or 1 mgd per square mile. Water in aquifers tapped by wells generally contains less than 500 mg/l (milligrams per liter) dissolved solids. The water generally is soft to moderately hard. Water in streams is soft to moderately hard and low in dissolved solids. Estimated water use in 1966 was 43.5 mgd of which 10.9 mgd was ground water and 32.6 mgd was surface water. Lava flows underlie the entire basin, and unconsolidated sedimentary deposits overlie the lavas in the Camas Prairie-Glenwood area and in small areas elsewhere. A spring supplies water to much of the Camas Prairie-Glenwood area through a public system, so not many wells are used now. About 56 million gallons (110 acre-feet) of ground water was used in 1974. The unconsolidated deposits yield from 1 to 500 gallons per minute of water to wells, and the basalt can yield more than 100 gallons per minute and possibly several thousand gallons per minute to deep wells. Ground-water recharge and discharge on the reservation is estimated to average 550,000 acre-feet per year.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75518","usgsCitation":"Cline, D.R., 1976, Reconnaissance of the water resources of the upper Klickitat River Basin, Yakima Indian Reservation, Washington: U.S. Geological Survey Open-File Report 75-518, vi, 54 p., https://doi.org/10.3133/ofr75518.","productDescription":"vi, 54 p.","numberOfPages":"59","costCenters":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"links":[{"id":146345,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0518/report-thumb.jpg"},{"id":41505,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0518/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":389662,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_15195.htm"}],"country":"United States","state":"Washington","otherGeospatial":"Klickitat River basin, Yakima Indian Reservation","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.5,\n              45.85\n            ],\n            [\n              -120.85,\n              45.85\n            ],\n            [\n              -120.85,\n              46.5\n            ],\n            [\n              -121.5,\n              46.5\n            ],\n            [\n              -121.5,\n              45.85\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a62e4b07f02db6368a4","contributors":{"authors":[{"text":"Cline, Denzel R.","contributorId":87910,"corporation":false,"usgs":true,"family":"Cline","given":"Denzel","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":167173,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.
