Preliminary design study for a National Digital Seismograph Network Preliminary design study for a National Digital Seismograph Network
Recently, the National Research Council published a report by the Panel on National, Regional, and Local Seismograph Networks of the Committee on Seismology in which the principal recommendation was for the establishment of a national digital seismograph network (NDSN). The Panel Report (Bolt, 1980) addresses both the need and the scientific requirements for the new national network. The...

Earthquake-triggered landslides form lakes in New Zealand Earthquake-triggered landslides form lakes in New Zealand
Eleven small lakes were formed by landslides caused by the 1929 Buller earthquake in New Zealand; four others were formed by other historic earthquakes in this country. At least nine other New Zealand lakes are dammed by landslides and were probably formed by prehistoric earthquakes. Earthquake-dammed lakes could provide an estimate of paleoseimicity for the past few hundred or thousand...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1981 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1981
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.

Annual and semiannual variations of the geomagnetic field at equatorial locations Annual and semiannual variations of the geomagnetic field at equatorial locations
For a year of quiet solar-activity level, geomagnetic records from American hemisphere observatories located between about 0?? and 30?? north geomagnetic latitude were used to compare the annual and semiannual variations of the geomagnetic field associated with three separate contributions: (a) the quiet-day midnight level, MDT; (b) the solar-quiet daily variation, Sq; (c) the quiet-time...

Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington
Observations of 167 small, shallow landslides spanning a 22-year period on extensively logged slopes of Quaternary terraces in the lower Skagit and Baker Valleys, Washington, shows that there is a relationship between the common slope failures in this area and the slope angle, stratigraphy, and logging practices. Landslide frequency increases upvalley, as do mean annual precipitation and...
