Other Seismic Networks, incl. Geothermal and Research Networks

A variety of seismic networks are operated in the Western US to monitor geothermal systems and energy production and to provide data for a variety of research purposes. Some of these networks are no longer operating, but their data are still available through the NCEDC.

Network List

• Enhanced Geothermal Systems, the Geysers and NV, Calpine/LBL (BG, formerly UG, 3B, 4B, 5B, opens as a separate page)
• Leo Brady Seismic Network (LB)
• Los Angeles Basin Seismic Network (LA)
• UC Santa Barbara Engineering Seismology Network (SB)
• San Andreas Fault Observatory at Depth, Earthscope (SF)
• EarthScope Transportable Array, USArray (TA)
• University of Oregon Regional Seismic Network (UO)
• United States National Seismic Network, USNSN (US)
• Pacific Northwest Seismic Network, PNSN (UW)

Data access

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
  • SeismiQuery at the NCEDC
• Access data through NCEDC web services

Leo Brady Seismic Network (LB)

Operated by Sandia National Laboratories, the Leo Brady Seismic Network consists of a few stations in Nevadah, Utah, and California, surrounding the Nevada Test Site. The NCEDC archives data from one station, DAC, in Darwin, CA.

• LB Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).

Los Angeles Basin Seismic Network (LA)

In 1988, the NCEDC archived ~40 days of data from two stations in the Los Angeles Basin Seismic Network: DHB near Culver City and GFP near the Hollywood Reservoir.

• LA Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED format only).

UC Santa Barbara Engineering Seismology Network (SB)

From NEES at UCSB: The NEES@UCSB (now primarily funded by the NRC) facility consists of permanently-instrumented geotechnical test sites designed to improve our understanding of the effects of surface geology on strong ground motion. The instrumentation at these sites includes surface and borehole arrays of accelerometers and pore pressure transducers designed to record strong ground motions, excess pore pressure generation and liquefaction that occurs during large earthquakes. An instrumented structure (at the GVDA site) is also monitored to improve our understanding of soil-foundation-structure interaction (SFSI) effects.

• SB Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).

San Andreas Fault Observatory at Depth, Earthscope (SF)

Waveform data from SAFOD is available from the NCEDC archive.

• EarthScope SAFOD web page
• SF Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).

EarthScope Transportable Array, USArray (TA)

The Earthscope Transportable Array is a network of 400 temporary stations being deployed in stages across the continental US and Alaska. Since 2011, the NCEDC currently archives waveforms from a small number of these stations sited in southern Oregon and far northern California. The archive also contains data from the Transportable Array's initial deployment across northern and central California in 2005-2007.

• USArray data and station information (USArray website)
• TA Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).

The IRIS DMC is the primary archive for USArray data.

University of Oregon Regional Seismic Network (UO)

The NCEDC archives data from station DBO in Dodson Butte, OR.

• UO Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).

United States National Seismic Network, USNSN (US)

The NCEDC archives data from USNSN stations ELK in Elko, NV and WVOR in Wild Horse Valley, OR. The archive contains 1994-2006 data for station MNV (Mina, NV).

• US Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).
  
  

Pacific Northwest Seismic Network, PNSN (UW)

The PNSN is Operated by the University of Washington. The NCEDC archives data from a small subset of PNSN stations that contribute to the NCSS.

• UW Network Information (PNSN website)
• UW Information Directory, including list of station locations, list of available channels (yy/mm/dd and yyyy.doy formats), and instrument response (SEED and simplified format).
