Digital processing of array seismic recordings

This technical letter contains a brief review of the operations which are involved in digital processing of array seismic recordings by the methods of velocity filtering, summation, cross-multiplication and integration, and by combinations of these operations (the "UK Method" and multiple correlation). Examples are presented of analyses by the...

Times and locations of explosions; U.S. Geological Survey 1962 field season

The U.S. Geological Survey detonated 86 large charges of chemical explosives in the western United States from 6 June to 9 August 1962, in a study of crustal structure in the western United States. This Technical Letter consists of two tables containing information about these explosions. Table I gives a brief geographical description of the...

Crustal structure along the coast of California from seismic-refraction measurements

Two reversed seismic-refraction profiles were recorded between Los Angeles and San Francisco in 1961. The three shotpoints were located in Santa Monica Bay, offshore near San Francisco, and at Camp Roberts, about halfway between Los Angeles and San Francisco. The velocity of Pg along these profiles is 6.1 ± 0.1 km/sec, with possible...

Fish kill from underwater explosions

The U.S. Geological Survey has used 23 different shotpoints during two seasons of field work in our seismic study of crustal structure in western United States. Without exception, it has been found that under-water shotpoints result in a more efficient conversion of explosive energy into seismic energy than do drilled-hole shotpoints. This...

Landslide conditions along the Ferry County highway parallelling Lake Roosevelt from Kettle Falls to the mouth of the Spokane River, Washington

As part of the program of the U.S. Geological Survey, landslides are being studied in several localities in the United States. These studies are directed toward assembling criteria for recognition of landslides, classification, and cataloging of remedial or control methods that have been effective.  In the gorge of the Columbia Ricer in...

The landslide of Sainte-Adresse cliff

The Sainte-Adresse Cliff in the neighborhood of Le Havre was subject in the past to repeated movements of greater of lesser scope which in 1944 have become markedly accentuated because of works on the "Atlantic Wall" and bomb and mine explosions. The situation became dangerous and required a complete study including geological and geotechnical...
