Arsenic in streams, stream sediments, and ground water, Fairbanks area, Alaska
Frederic H. Wilson, D. B. Hawkins
1978, Environmental Geology (2) 195-202
Arsenic concentrations of less than 5 ppb to as large as 1,260 ppb in stream waters and from 5 ppm to 4,000 ppm in stream sediments were found in the Pedro Dome-Cleary Summit area, Alaska. Waters from three of 20 wells sampled had arsenic concentrations exceeding the U.S. Public Health...
Earthquakes, March-April 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 192-194
Earthquakes caused fatalities in Mexico and Sicily; injuries and damage were sustained in eastern Kazakh SSR and Yugoslavia. There were four major earthquakes; one south of Honshu, Japan, two in the Kuril Islands region, and one in the Soviet Union. The United States experienced a number of earthquakes, but only...
Amplitude of foreshocks as a possible seismic precursor to earthquakes
A.G. Lindh
1978, Earthquake Information Bulletin (USGS) (10) 162-164
In recent years, we have made significant progress in being able to recognize the long-range pattern of events that precede large earthquakes. For example, in a recent issue of the Earthquake Information Bulletin, we saw how the pioneering work of S.A. Fedotov of the U.S.S.R in the Kamchatka-Kurile Islands region has...
Earthquakes; July-August 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 26-27
July and August were somewhat active seismically speaking, compared to previous months of this year. There were seven earthquakes having magnitudes of 6.5 or greater. The largest was a magnitudes of 6.5 or greater. The largest was a magnitude 8.0 earthquake south of Sumbawa Island on August 19 that killed...
Earthquakes; November-December, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (11) 110-112
Seismically speaking, the last 2 months were the most active of the year. There were six major earthuakes having magnitudes (M) ranging from 7.0 to 7.9 throughout the world: the Solomon Islands, Mexico (the largest of the year, M=7.9), the Kuril Islands, Taiwan, the Philippine Islands, and western Iran. THe...
Earthquakes; January-February, 1978
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 148-149
Seismically speaking, 1978 began slowly. The first major earthquake (magnitude 7.0 and above) of the year occurred on February 9 and was centered in the Kermadec Islands region in the South Pacific Ocean. The first destructive earthquake of the year strukc southern Honshu, Japan, on January 14. The magnitude 6.5...
Earthquakes, November-December 1977
W. J. Person
1978, Earthquake Information Bulletin (USGS) (10) 97-99
Two major earthquakes occurred in the last 2 months of the year. A magnitude 7.0 earthquake struck San Juan Province, Argentina, on November 23, causing fatalities and damage. The second major earthquake was a magnitude 7.0 in the Bonin Islands region, an unpopulated area. On December 19, Iran experienced a...
Quality of water in Pascagoula and Escatawpa Rivers, Jackson County, Mississippi
Gene A. Bednar
1978, Open-File Report 78-913
The chemical and physical properties and the range of concentrations of most constituents in water in the Pascagoula and Escatawpa Rivers during the period May 17-19, 1977, varied rapidly between high and low tides, primarily as the result of interactions of freshwater inflow with highly mineralized Gulf waters. The water...
Water-level monitoring in the area of the Palmdale Uplift, Southern California
D.L. Lamar, P.M. Merifield
1978, Earthquake Information Bulletin (USGS) (10) 144-147
Abnormal behavior of water levels in wells has been observed prior to a number of earthquakes. For instance, water-level minima have been noted in the Cienega Winery well before earthquakes on the San Andreas fault. Abnormal water-level fluctuations were used in conjunctions with other precursors to predict the February 4,...
Radon emanation on the San Andreas Fault
C. Y. King
1978, Earthquake Information Bulletin (USGS) (10) 136-138
Radon is a radioactive gas with a half-life of 3.8 days. (Half-life is the time required for the substance to lose half of its radioactivity by decay.) It is itself produced by the decay of uranium. Radon is constantly emanated from the Earth into the atmosphere. Many cases are known...
Empirical model of Skeletonema costatum photosynthetic rate, with applications in the San Francisco Bay estuary
James E. Cloern
1978, Advances in Water Resources (1) 267-274
An empirical model of Skeletonema costatum photosynthetic rate is developed and fit to measurements of photosynthesis selected from the literature. Because the model acknowledges existence of: 1) a light-temperature interaction (by allowing optimum irradiance to vary with temperature), 2) light inhibition, 3) temperature inhibition, and 4) a salinity effect, it accurately estimates...
