1982, Earthquake Information Bulletin (USGS) (14) 115-118
The last 2 months of the year were somewhat active, seismically speaking, including three major earthquakes (7.0-7.9) during the month of December. The first of the major quakes was in the Aegean Sea on December 19, and the other two were in the South Pacific in the Kermadee Islands on...
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...
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,...
USGS aerial resolution targets.
P.H. Salamonowicz
1982, Photogrammetric Engineering and Remote Sensing (48) 1469-1473
It is necessary to measure the achievable resolution of any airborne sensor that is to be used for metric purposes. Laboratory calibration facilities may be inadequate or inappropriate for determining the resolution of non-photographic sensors such as optical-mechanical scanners, television imaging tubes, and linear arrays. However, large target arrays imaged...
Petrology and trace element geochemistry of the Honolulu volcanics, Oahu: Implications for the oceanic mantle below Hawaii
D.A. Clague, F.A. Frey
1982, Journal of Petrology (23) 447-504
The Honolulu Volcanics comprises small volume, late-stage (post-erosional) vents along rifts cutting the older massive Koolau tholeütic shield on Oahu, Hawaii. Most of these lavas and tuff of the Honolulu Volcanics have geochemical features expected of near-primary magmas derived from a peridotite source containing Fo87–89 olivine; e. g. 100 Mg/(Mg...
The solubilities of calcite, aragonite and vaterite in CO2-H2O solutions between 0 and 90°C, and an evaluation of the aqueous model for the system CaCO3-CO2-H2O
Niel Plummer, Eurybiades Busenberg
1982, Geochimica et Cosmochimica Acta (46) 1011-1040
Calculations based on approximately 350 new measurements (CaT-PCO2) of the solubilities of calcite, aragonite and vaterite in CO2-H2O solutions between 0 and 90°C indicate the following values for the log of the equilibrium constants KC, KA, and KV respectively, for the reaction CaCO3(s) = Ca2+ + CO2−3: <img...
Earthquakes of Loihi submarine volcano and the Hawaiian hot spot
F. W. Klein
1982, Journal of Geophysical Research Solid Earth (87) 7719-7726
Loihi is an active submarine volcano located 35 km south of the island of Hawaii and may eventually grow to be the next and southernmost island in the Hawaiian chain. The Hawaiian Volcano Observatory recorded two major earthquake swarms located there in 1971–1972 and 1975 which were probably associated with...
Impact of Mount St. Helens eruption on hydrology and water quality
J. E. Bonelli, Howard E. Taylor, J.M. Klein
1982, Technical Report N-8311538
The 1980 eruptions of Mount St. Helens in southeast Washington resulted in a pronounced effect on the surface and ground water resources of the state. In response to the volcanic activity, the U.S. Geological Survey intensified statewide surface and ground water sampling programs to determine the nature and magnitude of...

Hydrology of Wisconsin wetlands
R.P. Novitzki
1982, Wisconsin Geological & Natural History Survey Information Circular 40
Data from 15 wetland study sites, supplemented by data from reconnaissance visits to 219 additional wetlands, were used to describe the hydrologic characteristics of Wisconsin wetlands and to suggest a simple hydrologic classification system. Wisconsin's wetlands OCCUf in depressions and on slopes. They may be in contact with ground water...
Relation between freshwater flow and salinity distributions in the Alafia River, Bullfrog Creek, and Hillsborough Bay, Florida

1981, Water-Resources Investigations Report 80-102
Data on streamflow, tide stage, specific conductance, and chloride concentration were collected in the Alafia River and Bullfrog Creek to describe the salinity and physical characteristics of the saltwater wedge. The location of the saltwater-freshwater interface for both streams was described by multiple regression equations involving streamflow and tide stage....
