Cruise report; RV Coastal Surveyor Cruise C1-99; multibeam mapping of the Long Beach, California continental shelf; April 12 through May 19, 1999
James V. Gardner, John E. Hughes Clarke, Larry A. Mayer
1999, Open-File Report 99-360
The greater Los Angeles area of California is home to more than 10 million people. This large population puts increased pressure on the adjacent offshore continental shelf and margin with activities such as ocean disposal for dredged spoils, explosive disposal, waste-water outfall, and commercial fishing. The increased utilization of the...
Assessment of landslide hazards in Kaluanui and Maakua gulches, Oahu, Hawaii, following the 9 May 1999 Sacred Falls landslide
R.W. Jibson, R.L. Baum
1999, Open-File Report 99-364
One of the injured hikers later died of injuries received in the landslide. Governor Ben Cayetano of Hawaii ordered that the park be closed due to concern about continuing landslide hazard near the falls. Subsequently, Bill Meyer, District Chief for the U.S. Geological Survey (USGS) Water Resources Division in Honolulu...
Timing of paleoearthquakes on the northern Hayward Fault: Preliminary evidence in El Cerrito, California
J. J. Lienkaemper, David P. Schwartz, K. I. Kelson, W. R. Lettis, Gary D. Simpson, J. R. Southon, J. A. Wanket, P. L. Williams
1999, Open-File Report 99-318
The Working Group on California Earthquake Probabilities estimated that the northern Hayward fault had the highest probability (0.28) of producing a M7 Bay Area earthquake in 30 years (WGCEP, 1990). This probability was based, in part, on the assumption that the last large earthquake occurred on this segment in 1836....
Geochemical investigations and interim recommendations for priority abandoned mine sites, BLM lands, upper Animas River watershed, San Juan County, Colorado
J. Thomas Nash
1999, Open-File Report 99-323
Field observations, sampling of mine dumps and mine drainage waters, and laboratory studies of dump materials have been made at mining areas deemed to be on public lands administered by the U. S. Bureau of Land Management (BLM) in the Upper Animas River watershed. Results of chemical analyses of dump materials, leachates of those...
SEGY to ASCII: Conversion and Plotting Program
Mark R. Goldman
1999, Open-File Report 99-126
This report documents a computer program to convert standard 4 byte, IBM floating point SEGY files to ASCII xyz format. The program then optionally plots the seismic data using the GMT plotting package. The material for this publication is contained in a standard tar file (of99-126.tar) that is uncompressed and...
Wide-angle seismic recordings from the 1998 Seismic Hazards Investigation of Puget Sound (SHIPS), western Washington and British Columbia
Thomas M. Brocher, Tom Parsons, Ken C. Creager, Robert S. Crosson, Neill P. Symons, George D. Spence, Barry C. Zelt, Philip T.C. Hammer, Roy D. Hyndman, David C. Mosher, Anne M. Trehu, Kate C. Miller, Uri S. ten Brink, Michael A. Fisher, Thomas L. Pratt, Marcos G. Alvarez, Bruce C. Beaudoin, Keith E. Louden, Craig S. Weaver
1999, Open-File Report 99-314
This report describes the acquisition and processing of deep-crustal wide-angle seismic reflection and refraction data obtained in the vicinity of Puget Lowland, the Strait of Juan de Fuca, and Georgia Strait, western Washington and southwestern British Columbia, in March 1998 during the Seismic Hazards Investigation of Puget Sound (SHIPS). As...
Digital analytical data from mineral resource assessments of national forest lands in Washington
D. E. Boleneus, D. W. Chase
1999, Open-File Report 99-344-A
Extensive reconnaissance assessments of the mineral resource potential of the Colville and Okanogan National Forests in northeastern Washington were conducted during 1979-1982 by a private consultant A.R. Grant, under contract with the U.S. Department of Agriculture, Forest Service. These forests occupy large parts of Pend Oreille, Stevens, Ferry, and Okanogan...
Quantitative paleoclimatic reconstructions from late Pleistocene plant macrofossils of the Yucca Mountain region
R.S. Thompson, K. H. Anderson, P. J. Bartlein
1999, Open-File Report 99-338
Plant macrofossil assemblages recovered from packrat (Neotoma) middens of late Pleistocene age from the present-day Mojave Desert of southern Nevada contain plant species that today live at higher elevations and/or farther north than the midden collection sites. Previous reconstructions of late Pleistocene climates from packrat midden assemblages in this region...
Thickness of Cenozoic Deposits of Yucca Flat Inferred from Gravity Data, Nevada Test Site, Nevada
G. A. Phelps, V.E. Langenheim, R.C. Jachens
1999, Open-File Report 99-310
The basin-basement contact for Yucca Flat was modeled using isostatic gravity data, a linear density-depth function for the basin deposits, and drill-hole constraints to produce a digital database of both the depth to basement and the gravitational anomaly associated with the basement rocks. The model predicts a depth of roughly...
1997 volcanic activity in Alaska and Kamchatka: summary of events and response of the Alaska Volcano Observatory
Robert G. McGimsey, Kristi L. Wallace
1999, Open-File Report 99-448
The Alaska Volcano Observatory (AVO) monitors over 40 historically active volcanoes along the Aleutian Arc. Twenty are seismically monitored and for the rest, the AVO monitoring program relies mainly on pilot reports, observations of local residents and ship crews, and daily analysis of satellite images. In 1997, AVO responded to...
