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...
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...

There were four major earthquakes (7.0-7.9) during this reporting period: two struck in Mexico, one in El Salvador, and one in teh Kuril Islands. Mexico, El Salvador, and China experienced fatalities from earthquakes. In the United States, a number of earthquakes occurred, but only one, in Utah caused some minor damage. ...
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...

Earthquakes, September-October 1981
W. J. Person
1982, Earthquake Information Bulletin (USGS) (14) 67-70
There were three major earthquakes (7.0-7.9) during this reporting period. The first and largest was a magnitude 7.7 on September 1 in the Samoa Islands region in the South Pacific. A magnitude 7.2 occurred on October 16 off the coast of central Chile. The third, on October 25 in Michoacan,...
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...
Digital model of predevelopment flow in the Tertiary limestone (Floridan) aquifer system in west-central Florida
Paul D. Ryder
1982, Water-Resources Investigations Report 81-54
A computer model was calibrated to approximate predevelopment flow conditions in a multilayered aquifer system in 10,600 square miles in west-central Floria. The lowermost aquifer, called the Floridan aquifer, is confined in most of the study area and consists of carbonate rocks ranging up to 1,300 feet thick. The Floridan...

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...
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...
Distribution, mineralogy, and texture of manganese nodules and their relation to sedimentation at DOMES Site A in the equatorial North Pacific
David Z. Piper, J. R. Blueford
1982, Deep Sea Research Part A, Oceanographic Research Papers (29) 927-951
DOMES Site A, in the equatorial North Pacific, was surveyed in detail in an attempt to relate the distribution of nodules to sedimentation. The sea floor is characterized by a broad east-west-trending valley defined by strongly dissected highlands to the north and...

Present conditions and sedimentary evolution of the shallow offshore region near Nauset Inlet on Cape Cod, Massachusetts were clarified using high-resolution seismic-reflection profiles, sidescan-sonar records, surface grab samples and current meter measurements. The study area contains three provinces: (1) a nearshore province (shallower than 18 m) with a relatively steep...

Five manganese nodules, including the USGS reference nodules A-1 and P-1, were analyzed for Co, Cu, Fe, K, Mg, Mn, Na, Ni and Zn without prior chemical separation by using a simultaneous multi-element atomic absorption spectrometer with an air—cetylene flame. The nodules were prepared in three digestion matrices. One of...

D.A. Cacchione, D.E. Drake, P. Wiberg
1982, Geologie en Mijnbouw (61) 71-78
We have used long-term measurements of near-bottom velocities at four heights above the sea floor in Norton Sound, Alaska, to compute hourly values of shear velocity u., roughness and bottom-drag coefficient. Maximum sediment resuspension and transport, predicted for periods when the computed value of u. exceeds a critical level, occur...
