KCC - Kaiser Creek, CA, USA
- Location:
-
Site is located near Mammoth Pool in Kaiser Creek, California,
and is under the auspices of
Southern California Edison. This site is operated cooperatively with
UC Santa Cruz.
- Geology:
-
Granite
- Vault/Borehole conditions:
-
The instruments are sited on a pier in one
of the Southern California Edison tunnels
for Mammoth Pool. In winters of especially high
rain or snowfall, SCE will open the valve in the back of
the tunnel to release water from Mammoth Pool. The
noise from the flowing water is extremeley high.
After a week or two, the valve will be shut and the
noise reduced. The valve was opened in 1996 (Feb),
1997 (Jan), 2000 (May).

- This section summarizes major changes in equipment or in instrumentation at KCC.
- 06/15/2004: Changed BH channels sampling rate to 40 Hz.
- 12/17/1999: Q980 software upgraded to MSHEAR.
- 01/29/1998: Upgraded Q980 with 4 GB disk.
- 07/24/1997: Installed warpless baseplates.
- 10/02/1996: Replaced EW STS-1.
- 01/10/1996: Replaced Q980 datalogger, due to digitizer failure.
- 12/06/1995: Streckeisen STS-1 broadband seismometers with Quanterra 980
Datalogger and Kinemetrics FBA-23 strong
motion accelerometer installed.
- Noise Characteristics:

- 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.
- Querying the archives
- Requesting data
Help on using these
tools is available.
