HUMO - Hull Mountain, OR, 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.

Borehole Conditions
The equipment is located in a side adit of a hard-rock mine approximately 100 meters from the entrance. Overburden is approximately 50 meters. The sensors are located on a concrete pier covered with 4" of rigid foam insulation.The datalogger, dial-up modem, and fiber optic modems are located in a plastic garden shed about 8 meters from the pier. Batteries are located in a large plastic storage box next to the shed. The tunnel entrance is covered with a hinged steel grate to allow free passage of bats. Humidity is 100% outside the enclosures. Telemetry is through 300 meters of fiber optic cable connected to a satellite system.
