Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: December 1976 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: December 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.

Landslides - Cause and effect Landslides - Cause and effect
Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. Slope movement in general is a major process of the geologic environment that places...

In-situ measurements of seismic velocities in the San Francisco Bay region...Part II In-situ measurements of seismic velocities in the San Francisco Bay region...Part II
Seismic wave velocities (compressional and shear) are important parameters for determining the seismic response characteristics of various geologic units when subjected to strong earthquake ground shaking. Seismic velocities of various units often show a strong correlation with the amounts of damage following large earthquakes and have been used as a basis for certain types of seismic...

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...
