Title: Development of discrimination, detection, and location capabilities in central and southern Asia using middle-period surface waves recorded by a regional array. Scientific report No. 1

Technical Report ·
OSTI ID:415894

This research is dedicated to the investigation of the relevance and use of intermediate period (5 - 25 s) surface wave data in problems of detection, discrimination, and the accurate location of small events using regional array data. It is focused on analysis of data from earthquakes throughout Central and Southern Asia and the Middle East and nuclear explosions at Lop Nor within 15 - 25 degrees of the Kyrghiz Telemetered Seismic Network. The main efforts during the 6.5-month time period covered by this report were directed to data collection and preprocessing, software development, measurements of surface wave characteristics, and constructing `master curves` for clusters of events in specific regions. In the next year, we will greatly increase the volume of processed data and construct group velocity maps for Central and Southern Asia. The expected weak surface wave signals recorded by a network and improvement of the regional model of the lithosphere. This will provide means to enhance detection and location capabilities.
