JAS - Jamestown, CA, USA

We operate broadband and borehole stations under the network code BK. The Berkeley Digital Seismic Network (BDSN) is a regional network of very broadband and strong motion seismic stations designed to monitor regional seismic activity as well as provide high quality data. The Berkeley borehole stations have borehole geophones or other seismic sensors and may have other geophysical instrumentation.

The site was located in Jamestown, California, and operated in cooperation with the California Department of Water Resources, beginning in 1964. This station was relocated to JAS1 when the rising price of gold in the mid-1980s led to renewed mining activity.

JAS (and JAS1) were part of the USGS Digital World Wide Standard Seismograph Network (DWWSSN), the digital descendant of the WWSSN.
