- Location:
-
Site is located on
BLM land on Hull Mountain, Oregon.
HUMO is a cooperative station with the Advanced National Seismic System and the Global Seismic Network.
- Geology:
-
Payne Cliffs formation - sandstone and siltstone
- Vault/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.

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.- Querying the archives
- Requesting data by channel and time
- Requesting data by event
Help on using these tools is available.
