1977, Report
Pictures of the Earth's surface obtained from satellites are providing scientists with new tools to investigate the Earth and its environment. At the same time, a growing population and an ever-expanding technology place unprecedented demands on natural resources. Man can no longer treat his resources strictly according to immediate economic...

A solute-transport model that can be used to predict the movement of dissolved chemicals in flowing ground water was applied to a problem of ground-water contamination at the Rocky Mountain Arsenal, near Denver, Colo. The model couples a finite-difference solution to the ground-water flow equation with the method-of-characteristics solution to...

During September, 1976, a series of gravity measurements was made in the western Beaufort Sea and the northern Chukchi Sea on ice floes and on a grounded ice island. The data were taken to evaluate the technique of measuring gravity on small ice floes in summer and to supplement and...

The Spokane Valley-Rathdrum Prairie aquifer is composed of unconsolidated Quaternary glaciofluvial deposits underlying an area of about 350 square miles. Transmissivities in the aquifer range from about 0.13 million to 11 million feet squared per day and ground-water velocities exceed 60 feet per day in some areas. The water-table gradient...

The exploration for and development of ground water described in this report consisted of the drilling and testing of 22 holes and the conversion of 8 of the holes into production wells on the island of Moen, Truk Islands, in the period November 1975 to July 1976. The objective of...

Virginia is a State of considerable seismic activity, although the earthquakes are rarely strong. Thirty-five shocks, intensity MM V or greater (Modified Mercalli Scale), are listed with epicenters within its borders. The locations of several of the older events are not precise; thus, the above count i subject to alteration....

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. ...

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...

The western part of the State was shaken strongly by the New Madrid, Mo., earthquakes of 1811-12 and by earthquakes in 1843 and 1895. The area has also experienced minor shocks. Additional activity has occurred in the eastern part of the State, near the North Carolina border. Forty shocks of...

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. ...

To supplement data in the report Preliminary Determination of Epicenters (PDE), the National earthquake Information Service (NEIS) also publishes a quarterly circular, Earthquakes in the United States. This provides information on the felt area of U.S earthquakes and their intensity. The main purpose is to describe the larger effects of these earthquakes so that...

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...

In 1811-12, a series of disastrous earthquakes struck the southeast Missouri region (see "The Mississippi Valley earthquakes of 1811 and 1812" by Otto W. Nuttli in the Earthquake Information Bulletin, March-April 1974). Earthquake activity continues in the area at present, showing that the seismic hazard is still there. We know little about the...

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...

In 1966, it was discovered that high pressure injection of industrial waste fluids into the subsurface near Denver, Colo., was triggering earthquakes. While this was disturbing at the time, it was also exciting because there was immediate speculation that here at last was a mechanism to control earthquakes. ...

A recurrence of an 1811-12 type earthquake in the Mississippi Valley would pose severe problems to construction in the valley. As William Stauder has stated in the preceding article, a particular difficulty in understanding the seismicity of this area is that, whereas various surface manifestations of the 1811-12 earthquakes have...

A global network of seismographs is as indispensable to seismologists as telescopes are to astronomers. The network is used to catalog the thousands of earthquakes that occur each year and to provide the data needed for detailed studies of earthquake mechanisms, deep Earth structure, and tectonic processes. Like astronomy, seismology...

With rapid approach of a capability to make reliable earthquake forecasts, it essential that the Federal Government play a strong, positive role in formulating and implementing plans to reduce earthquake hazards. Many steps are being taken in this direction, with the President looking to the Office of Science and Technology...
