Landslides Landslides
Landslides are frequent in areas where there is high seismicity and steep slopes. Landslides associated with earthquakes may cause as much damage as the initial ground shaking. They may also occur long after the earthquake. Some of the major earthquakes that have occurred during the past 15 years demonstrate the hazards of seismically triggered landslides.

Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1977 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1977
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.

Catalog of seismograph stations operated in support of the ERDA Nevada Operations Office, January 1964 thru June 1976 Catalog of seismograph stations operated in support of the ERDA Nevada Operations Office, January 1964 thru June 1976
The seismograph stations listed in this catalog were established over the period January 1964 through June 1976 in support of the Energy Research and Development Administration, Nevada (ERDA/NV) underground weapons testing program at the Nevada Test Site (NTS), central Nevada, and Amchitka, Alaska. For station listings before 1964 see Coast and Geodetic Survey publication, "Seismic Data...

In-situ measurements of seismic velocities in the San Francisco Bay Region; part III In-situ measurements of seismic velocities in the San Francisco Bay Region; part III
Seismic wave velocities (compressional and shear) are important parameters for estimating 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...
