The earthquake activity during this reporting period was somewhat quiet as far a significant earthquakes were concerned. There were no major [magnitude (m)=7.0-7.9] earthquakes during this reporting period, but five people were reported killed in Peru from earthquakes on March 24 and 28. A number earthquakes occurred in the United States,...

Jack London and the San Francisco earthquake
J.S. Sachs
1982, Earthquake Information Bulletin (USGS) (14) 94-97
After it was over, it seemed to many, and especially to eyewitnesses like Jack London, that the earthquake and fire had devastated San Francisco. However people were confident that, like the phoeniz, San Francisco would rise from the ashes and regain her palce as the "Imperial City of the West." ...

The U. S. Geological Survey Geologic Hazards Program
D. L. Peck
1982, Earthquake Information Bulletin (USGS) (14) 182-182
In 1879, Congress established the U.S Geological Survey for "the classification of the public lands and the examination of the geological structure, mineral resources, and products of the national domain." Throughout the past 103 years, the Survey has successfully fulfilled these responsibilities, but it has also been responsive to changing...
Engineering aspects of seismological studies in Peru
L. Ocola
1982, Earthquake Information Bulletin (USGS) (14) 33-38
Large and small earthquakes occur frequently in Peru. Official institutions in charge of the study of seismological and geophysical aspects of such large natural events have a responsibility to provide engineers, planners, and government officials with basic data to implement safety measures to minimize the destructive impact of great earthquakes. The...
Progress of the seismological program in El Salvador
M. A. Martinez
1982, Earthquake Information Bulletin (USGS) (14) 39-43
El Salvador is located in Central America at the axis of geographical coordinates 14° north latitude and 89° west longitude. Situated inside the circumpacific "ring of fire" it is thus vulnerable to sudden earthquakes and volcanic eruptions. Since 1520, El Salvador has sustained approximately 40 destructive earthquakes, an average of one...
Seismology in Mexico
C. Lomnitz
1982, Earthquake Information Bulletin (USGS) (14) 30-32
Mexico is situated at the intersection of four major crustal Plates: the Americas Plate, the Pacific Plate, the Caribbean Plate, and the Cocos Plate. The interaction of these four plates is very complex. The pattern of earthquake risk is, therefore, among the most complicated in the world. The average release...
Volcanic hazard alert issued for the Long Valley-Mono Lake area of California
R. A. Kerr
1982, Earthquake Information Bulletin (USGS) (14) 84-93
The ski resort of Mammoth Lakes, nestled against the east front of the Sierra Nevada just east of Yosemite National Park, knows about natural hazards. It is still being shaken by an unusual sequence of earthquakes that started in 1978 and included four earthquakes of magnitude 6 within 48 hours...

Simulated effects of ground-water development on the potentiometric surface of the Floridan aquifer, west-central Florida
W.E. Wilson, J. M. Gerhart
1982, Professional Paper 1217
A digital model of two-dimensional ground-water flow was used to predict changes in the potentiometric surface of the Floridan aquifer, 1976 to 2000, in a 5,938-square-mile area of west-central Florida. In 1975, ground water withdrawn from the Floridan aquifer for irrigation, phosphate mines, other industries, and municipal supplies averaged about...
Sedimentology and stratigraphy of the Kanayut Conglomerate, central and western Brooks Range, Alaska: Report of 1981 field season
T. H. Nilsen, Thomas E. Moore
1982, Open-File Report 82-674
The Upper Devonian and Lower Mississippian(?) Kanayut Conglomerate forms a major stratigraphic unit along the crest of the Brooks Range of northern Alaska. It crops out for an east-west distance of about 900 km and a north-south distance of about 65 km. The Kanayut is wholly allochthonous and has probably...
Tilt measurements at Long Valley caldera, California, May-August 1982
Daniel Dzurisin, K. V. Cashman, D. A. Johnston, Arthur G. Sylvester
1982, Open-File Report 82-893
The Mammoth Lakes area in east-central California has experienced unusual seismicity and ground deformation since 1978, highlighted by four M>6 earthquakes in May 1980 and by the discovery soon thereafter of a broad uplift within Long Valley caldera. Recurrent seismic swarms during June 1980-May 1982 raised concern over the possibility...
Water-quality data for the American River basin, California, February-October 1979
J. M. Shay
1982, Open-File Report 82-363
Data were collected in the American River basin from February to October 1979 for use in assessing the water quality in the basin and developing land-use/water-quality relations. The basin covers 2,163 square miles of the western slope of the central Sierra Nevada. Basin headwaters are located primarily between Donner Summit...

Potential secondary hazards of Avitrol baits to sharp-shinned hawks and american kestrels
Nicholas R. Holler, Edward W. Schafer Jr.
1982, Journal of Wildlife Management (46) 457-462
Avitrol© is the registered trade name of a number of proprietary bird control products containing the active ingredient 4-aminopyridine (4-AP). Several formulations of Avitrol are available to pest control applicators for use in agricultural areas. Although individual treated bait particles contain from 0.5 to 3.0% 4-AP, the amount present in...
Paleomagnetic data from the Coso Range, California and current status of the Cobb Mountain normal geomagnetic polarity event
Edward A. Mankinen, C. Sherman Gromme
1982, Geophysical Research Letters (9) 1279-1282
Two basalt flows which erupted about 1.08 m.y. ago in the Coso Range, California, have normal magnetic polarity and thus provide additional evidence for the Cobb Mountain normal polarity event. A review of available data confirms that this event was of geomagnetic origin. A mean age of 1.10 ± 0.02...

Paleomagnetic field directions from the basalt of Pack Sack Lookout are compared to those from the Pomona Member of the Saddle Mountains Basalt of the Columbia River Basalt Group. The Pomona crops out over a wide region on the Columbia Plateau east of the Cascade Range, and the basalt of...
Aversion substance(s) of the rat coagulating glands

1982, Journal of Chemical Ecology (8) 379-382
The aversive substance(s) present in adult male urine were not found in castrate rat urine. Removal of the coagulating glands also resulted in a loss of the aversion compounds. The aversion substances were restored to the urine after androgen treatment of the castrate rats....
Hydrates of natural gas in continental margins
K.A. Kvenvolden, L.A. Barnard
1982, Book chapter, Studies in continental margin geology
Natural gas hydrates in continental margin sediment can be inferred from the widespread occurrence of an anomalous seismic reflector which coincides with the predicted transition boundary at the base of the gas hydrate zone. Direct evidence of gas hydrates is provided by visual observations of sediments from the landward wall...
