Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 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.

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 zonation stud

Landslide problems at West Valley Nuclear Service Center, New York: An assessment and recommendations for study
Problems due to landslides prompted a visit to the West Valley Nuclear Service Center (WVNSC) near Springville, New York, on March 15 and 16, 1976. From this visit a report was prepared and contains the following:
An assessment of the landslide conditions.
An assessment of the immediacy of the landslide problems.
A suggested study program for reducing the landslide hazard to an acceptable level.

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 azimuths are com

15/16 ips Operation of the Precision Instrument Company Model P15100 tape recorder to record the standard (30 Hz) NCER seismic data multiplex system
In recent months the need has arisen to record special seismic networks consisting of a dozen or more standard NCER seismic systems telemetered to a central collection point on a reliable, portable, low-power tape recorder. Because of its simplicity and the ease with which it can be adapted for the purpose, the PI 5100 field recorder should be considered for such use. In the tests described here,
