Extension of the Caucasus Seismic Information Network Study into Central Asia
Abstract
The Central Asian Seismic Research Initiative (CASRI) is an extension of the Caucasus Seismic Information Network (CauSIN). Both projects seek to promote cooperation, transparency, and stability in these highly seismically active regions of strategic interest to the U.S. by working with the countries to improve the monitoring and hazard assessment. Building knowledge bases of geological, geophysical, and seismic information in the respective regions, utilizing modern crustal modeling techniques to create a combined model of the regions, and applying modern hazard assessment techniques will aid these countries in improving their seismic monitoring capacity. The CauSIN project was completed in 2007; the CASRI is currently in its final stages, though work in the area will be continued in a separate project. Over the past three years, a great deal of tectonic, geologic, geophysical, seismic event catalog, waveform, and phase arrival data from local networks in the CASRI region (Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan) have been collected. The historical catalog contains nearly 11,000 events from 500 AD through the present. The modern seismic catalog (from the digital instrumental period) includes 469 events from 1991 to 2005. In the past year, a large number of phase arrival time picks have been collected from stations of the local networks in Kazakhstan and Kyrgyzstan.
