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...

Frequency response of the USGS short period telemetered seismic system and its suitability for network studies of local earthquakes Frequency response of the USGS short period telemetered seismic system and its suitability for network studies of local earthquakes
The USGS telemetered seismic system was intended primarily to record small to moderate earthquakes (magnitude 0 to 4) at distances of a few km to several hundred km. Its frequency response is such that the recorded background noise at a moderately quite Coast Range site has a relatively flat 'record' spectrum from about 1/3 Hz to about 20 Hz. With the system magnification set so that the

Recent and relict topography of Boo Bee patch reef, Belize Recent and relict topography of Boo Bee patch reef, Belize
Five core borings were taken on and around Boo Bee Patch Reef to better understand the origin of such shelf lagoon reefs. The cores reveal 4 stages of development: (1) subaerial exposure of a Pleistocene "high" having about 8 meters of relief, possibly a Pleistocene patch reef; (2) deposition of peat and impermeable terrigenous clay 3 meters thick around the high; (3) initiation of...

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