PKD1 - Haliburton House, Parkfield, 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 PKD1 site was located at the Haliburton House in Parkfield, California, and under the auspices of the United States Geological Survey. This installation was undertaken as a temporary site while the search for a permanent station was conducted. The PKD site was installed in 1996, but dual recording continued until the USGS was asked to vacate Haliburton House in 2000.

Borehole Conditions

The pier was a 4 inch concrete slab poured directly on the clay-rich soils. The STS-2 was housed in a thermal isolation container which sits on the slab. The datalogger and support equipment are sited in an air conditioned room of an adjacent house. This site required frequent recentering of the broadband sensors.
