- 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.
- Instrumentation:
-

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.
