Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1976 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: October 1976
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Textural distribution of sea-floor sediments, south Texas Outer Continental Shelf Textural distribution of sea-floor sediments, south Texas Outer Continental Shelf
The general texture of sea-floor sediments along the south Texas Outer Continental Shelf was evaluated in terms of gravel, sand, silt, and clay components. The gravel component is quantitatively minor and is concentrated mainly in the southern sector; it consists, for the most part, of relict biogenic detritus dominated by molluscan shells. The sand component consists of terrigenous and...

Analysis of seismograms from a downhole array in sediments near San Francisco Bay Analysis of seismograms from a downhole array in sediments near San Francisco Bay
A four-level downhole array of three-component instruments was established on the southwest shore of San Francisco Bay to monitor the effect of the sediments on low-amplitude seismic ground motion. The deepest instrument is at a depth of 186 meters, two meters below the top of the Franciscan bedrock. Earthquake data from regional distances (29 km ≤ Δ ≤ 485 km) over a wide range of...

Crustal movement investigations Crustal movement investigations
Studies of horizontal crustal movement using conventional geodetic methods have been considerably expanded in the quadrennium 1971–1974. The basic fault monitor Geodimeter network now covers most of the major faults in California as well as the zone of faulting that extends into Nevada. Isolated Geodimeter networks in seismic areas of Montana, New Mexico, Utah, and Washington are also...

A model for earthquakes near Palisades Reservoir, southeast Idaho A model for earthquakes near Palisades Reservoir, southeast Idaho
The Palisades Reservoir seems to be triggering earthquakes: epicenters are concentrated near the reservoir, and quakes are concentrated in spring, when the reservoir level is highest or is rising most rapidly, and in fall, when the level is lowest. Both spring and fall quakes appear to be triggered by minor local stresses superposed on regional tectonic stresses; faulting is postulated...
