Seismic verification studies at Sandia
The Seismic Verification Program at Sandia focuses on designing and building seismic monitoring systems which could be deployed within the Soviet Union. To support this effort, Sandia also is involved in developing and testing seismic components, and in evaluating system performance and new monitoring techniques. Seismic studies conducted under the latter task concentrate on analyzing regional seismic signals, recorded within 2000 km of the source. In-country monitoring stations would be able to exploit these regional signals to improve on the capabilities of external stations at teleseismic ranges. The principal advantages which regional signals offer are greater amplitudes and broader frequency bands. However, such signals are more complex and less well understood than teleseismic records. Ongoing studies at Sandia will help define the performance which can be expected from an in-country network. Other studies are testing new monitoring concepts which may further improve in-country capabilities. This presentation gives a brief overview of some of these projects.
