The month of December was seismically quiet compared to the previous months of the year. There were no major earthquakes during the month and only one that caused fatalities. On December 8, the Republic of South Africa was struck by an earthquake that caused deaths and damage. The United States...

Earthquakes occur in a broad range of sizes. A rock burst in an Idaho silver mine may involve the fracture of 1 meter of rock; the 1965 Rat island earthquake in the Aleutian arc involved a 650-kilometer lenght of Earth's crust. Earthquakes can be even smaller and even larger. if...

October brought two damaging earthquakes to Ecuador and New Guinea. The Ecuador earthquake, although only magnitude 5.5, caused casualties and damage. The new Guinea earthquake, a major quake, caused a loss of life and damage. Two major earthquakes were experienced during November, in eastern Turkey on November 24 and in...

Seven earthquakes of intensity V or greater on the Modified Mercalli Scale (MM) are known to have originated within Vermont. Many additional shocks centered in other New England States and Canada have been strongly felt in Vermont. ...

Seismic-reflection profiles indicate that during the Pleistocene the Delaware River flowed across the continental shelf east of Delaware Bay and emptied into Wilmington Submarine Canyon. The ancestral valley (width, 3 to 8 kilometers; relief, 10 to 30 meters) is buried, is not reflected in the surface topography, and probably predates...

Three marine benthic faunal realms can be recognized in the Early and Middle Devonian. The Eastern Americas Realm consisted of most of the eastern half of North America and South America north of the Amazon. This realm extended in a southwest direction from the Devonian equator to approximately 35??S and...

Witherspoon, P.A. and Gale, J.E., 1977. Mechanical and hydraulic properties of rocks related to induced seismicity. Eng. Geol., 11(1): 23-55. The mechanical and hydraulic properties of fractured rocks are considered with regard to the role they play in induced seismicity. In many cases, the mechanical properties of fractures determine the...

Salmonella enteritidis serotype Rubislaw and Arizona hinshawii were isolated from cloacal swabs of "healthy" live-trapped sandhill cranes (Grus canadensis tabida) in Indiana and Wisconsin. These respective isolations were the first reported from wild sandhill cranes....

Volatile-filled vesicles are present in minor amounts in all samples of mid-ocean basalt yet collected (and presumably erupted) down to depths of 4.8 km. When such vesicles are pierced in liquid under standard conditions, the volume expansion of the gas is 0.2 ?? 0.05 times the eruption pressure in bars...

Robbins Nest is located on the fall line one-half mile below Rocky Gorge Reservoir. During the fall migration, about 8 nets are run on the upper part of the 3 acres (edge of the lawn, the garden, under the Virginia Pines, and the upper edge of the mature oak woods...

An automated method to determine both inorganic and organic forms of arsenic In water, water-suspended mixtures, and streambed materials Is described. Organic arsenic-containing compounds are decomposed by either ultraviolet radiation or by suHurlc acid-potassium persulfate digestion. The arsenic liberated, with Inorganic arsenic originally present, is reduced to arsine with sodium...

Experimental verification of earlier theoretical work for square wave voltammetry at the dropping mercury electrode is given. Experiments using ferric oxalate and cadmium(II) in HCl confirm excellent agreement with theory. Experimental peak heights and peak widths are found to be within 2% of calculated results. An example of trace analysis...

X-Ray diffraction and anisotropic magnetic measurements have been made on single crystals of lunar ilmenite and on terrestrial ilmenite from Bancroft, Ontario, Canada and the Ilmen Mountains, U.S.S.R. The elongated c">c-axis of lunar ilmenite, previously reported, is confirmed by new measurements. The shorter <span...

3-Chloro-4-methyl benzamine HCl (DRC-1339), an avian toxicant, was fed to five species of birds for periods up to 120 days. The 30-day LC50 of uniformly treated feed for starlings was 4.7 ppm and the 90-day LC50 was 1.0 ppm. The 28-day LC50 for coturnix was 18 ppm. The 30-day LC50 for pigeons was...

A total of 161 blood samples collected from 77 white-tailed does (Odocoileus virginianus borealis) during the years 1971 through 1974 in Minnesota were utilized to make a preliminary characterization of the estrogen and progesterone levels in pregnant and nonpregnant animals. Progesterone and estrogen were measured by radioimmunoassay. Progesterone levels during...

Twelve earthquakes of intensity V or greater (Modified Mercalli scale) have centered within the borders of South Dakota. All the shocks were rather localized, except that of 1911 which was felt over an area of approximately 100,000 km2. Some earthquakes from neighboring States were felt strongly in South Dakota. ...

1977, Book chapter, Estuarine processes: circulation, sediments, and transfer of material in the estuary
Differences in the relative magnitude and timing of wind stress and river inflow in the northern and southern reaches of San Francisco Bay create different sedimentary conditions. The northern reach is a partially to well mixed estuary receiving most of the total annual fresh-water input (840 m3 sec−1) and suspended sediment...

Seventeen earthquakes, intensity V or greater, have centered in Texas since 1882, when the first shock was reported. The strongest earthquake, a maximum intensity VIII, was in western Texas in 1931 and was felt over 1 165 000 km 2. Three shocks in the Panhandle region in 1925, 1936, and 1943...

This report contains climatologic and hydrologic data that were collected as a part of an investigation of the southeastern Uinta Basin, Utah and Colorado, by the U.S. Geological Survey. The data apply mainly to water years 1975 and 1976, which includes the period from October 1974 through September 1976. Included...

Heavy minerals in bottom-sediment samples of the lower Chesapeake Bay show distribution patterns and interrelationships that denote characteristic mineral suites associated with defined geographic provinces. The Baymouth province has a garnet-hornblende-pyroxene suite, which is largely attributed to the influx of littoral and shelf sediments; the Eastern Shore province has a...
