Location:
Site is located on private property in Modoc County, California, approximately 10 kilometers from the Oregon border and 20 kilometers from the Nevada border. MOD was established to replace MIN, which had become increasingly noisy due to traffic on route 36.

MOD is a cooperative station with the US National Seismic Network

Geology:
Pyroclastic Rock

Vault/Borehole conditions:
The vault is a horizontal tunnel, located beneath 5 meters of overburden to maintain thermal stability.

Data Availability:
BDSN waveforms and associated metadata are available at the Northern California Earthquake Data Center (NCEDC).

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.

Help on using these tools is available.
