JAS1 - 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.

Station Name JAS1

Site is located in Jamestown, California. The equipment from JAS was relocated to JAS1 07/03/1984, and then from JAS1 to CMB on 11/06/1986, at which time JAS1 was closed.

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

Borehole Conditions

Seismometers were temporarily located in a garage on a concrete floor while looking for a more permanent location. This site was noisy.
