Alaska Earthquake Information Center (AEIC): AEIC's mandate is to collect, analyze and archive seismic event data for the state of Alaska, providing information and assistance to the public as well as state and local agencies. The AEIC records data from an integrated network of more than 400 seismic sites distributed across the state and serves as the regional data center locating and reporting about 20,000 earthquakes per year.

The Broadband Array in Taiwan for Seismology (BATS) has been established by the Institute of Earth Sciences, Academia Sinica, Taiwan since 1995. Incorporated with the Central Weather Bureau, the station number deployed in the Taiwan region will be as many as 41, not including the planned and proposed stations, by the end of 2003. The Data Management Center of the Institute of Earth Sciences (DMC-IES), Academia Sinica, Taiwan (http://dmc.earth.sinica.edu.tw) is responsible of the BATS data archive, quality control, distribution, and the CMT inversion for regional earthquakes. We adopt a user-friendly data request interface (NINJA) that is developed by the OHPDMC, ERI, U. of Tokyo, to on-line distribute BATS waveform data. This dataset is available through either a NINJA application software or the BATS website.

The IRIS Data Management Center (DMC) is located in Seattle, Washington, just off the University of Washington campus where the Earth and Space Sciences acts as the host organization. The IRIS DMC receives earthquake and seismic data from a variety of Data Centers around the world and is responsible for the long term archive and distribution of all IRIS generated data. The IRIS DMC also acts as a Data Center for the International Federation of Digital Seismograph Networks (FDSN).

The IRIS/IDA Data Collection Center is a facility funded through the IRIS Data Management System to process data from the IDA portion of the IRIS Global Seismic Network and make them available to the research community at large. To this end, IDA DCC personnel routinely perform tasks that include, but are not limited to, maintaining contact with, and reviewing instructions for, station operators; documenting and reporting data problems; maintaining records of instrument response and equipment modifications; receiving, logging, and unpacking data; performing quality control and reviewing of that data to assess station performance; and reformatting and distributing data in a timely manner via the IRIS Data Management System.

Lamont-Doherty Cooperative Seismographic Network (LCSN) monitors earthquakes which occur primarily in the Eastern United States. The network has been operated since early '70s. The network consists of four sub-networks with Internet nodes: Palisades (node at Lamont-Doherty Earth Observatory, Palisades, NY), St. Lawrence (node at Potsdam College of Art & Science, SUNY, NY), Lake Champlain (node at Middlebury College, VT), Delaware (node at Delaware Geological Survey/Univ. Delaware, DE). There are over 20 short-period stations and 15 three-component, broadband stations covering New York, New Jersey, Delaware, Pennsylvania, Maryland and Vermont. Broadband stations record digital seismic signals continuously with a nominal sampling rate of 40 samples/sec, whereas short-period stations record signals continuously with 100 samples/sec. The LCSN also operates a half dozen of strong-motion accelerometers (CMG-5TD). Waveform data in SEED format can be obtained from this web site on AutoDRM and Data Access & Archive section and downloaded via ftp. Arrival times of the seismic phases are also available on this web site. The network has been operated jointly by LDEO and other institutions in the Northeastern United States. Major funds to operate the network have been provided by the US Geological Survey under the National Earthquake Hazard Reduction Program (NEHRP). LCSN is an active member of the Advanced National Seismic System (ANSS). More information on regional seismographic networks in the United States and recent earthquakes can be found on USGS.

The Montana Regional Seismograph Network is operated by the Montana Bureau of Mines and Geology with assistance from the Confederated Salish and Kootenai Tribes and the National Institute of Safety and Health. Two broadband stations are operated cooperatively with the US Geological Survey’s National Seismic Network Program. Most other sites are telemetered, short-period vertical stations. Network data are used to detect and locate local and regional earthquakes. Hypocenters and magnitudes for recent earthquakes are available on the MBMG website and are contributed to the Advanced National Seismograph System composite catalog (http://quake.geo.berkeley.edu/cnss/) on a monthly basis.

The Northern California Earthquake Data Center (NCEDC) is a joint project of the University of California Berkeley Seismological Laboratory (BSL) and the United States Geological Survey (USGS) . The NCEDC is a long-term archive and distribution center for seismological and geodetic data for Northern and Central California and is partially supported by funding from the USGS component of the National Earthquake Hazards Reduction Program (NEHRP) .

Since 1967 the U.S. Geological Survey has operated the Northern California Seismic Network (NCSN) to provide earthquake data for a wide range of research topics and hazard-reduction activities. The NCSN is designed to detect all local earthquakes having signal strength above the background level of microseisms. The network configuration was motivated by the need to monitor active faults and volcanoes with a station density sufficient to determine the focal depth of shallow (0-15 km) crustal earthquakes. Depending on the concentration of stations in a region, the magnitude (M) level at which earthquake detection is complete varies from approximately 1.4 in parts of the central Coast Ranges to 2.6 in the Klamath Mountain range. However, earthquakes with M<1.0 are routinely detected throughout the network.

The NCSN operates more than 430 stations in northern and central California and records an additional 100 stations maintained by 4 other institutions. It records over 1000 channels of data using a mix of digital and analog systems. Nearly one fourth of the stations in the network are digital with strong motion sensors. As of 2003 the NCSN operates 13 broadband stations and 11 are borehole installations. The remainder of the stations are mostly comprised of short-period vertical-component sensors. The NCSN telemetry system utlizes local collection nodes which are linked to Menlo Park via dedicated microwave, digital satellite telemetry, and leased digital circuits. The network also utilizes direct radio telemetry to Menlo Park and operates an extensive LAN that links urban stations located in the San Francisco Bay region. Available data include triggered waveforms, catalogs of hypocenters, phase and amplitude readings, and first-motion mechanisms.

The PNSN is the regional seismic network for the Pacific Northwest (Washington and Oregon). It includes approximately 120 short-period stations, 40 broad-band stations and 70 strong-motion stations (some are multiple band). Data recording and analysis is at the University of Washington; however there are five remote data collection nodes and three service centers (UofO, CVO, Battelle Northwest). Operation is funded by the US Geological Survey, US Department of Energy and the State of Washington.

The rest of the data is distributed through IRIS.

The Southern California Seismic Network (SCSN) is a cooperative project of Caltech and the US Geological Survey. The SCSN has benefited from numerous upgrade projects. TERRAscope, funded by the L. K. Whittier and ARCO Foundations, and NSF, provided the first 28 broadband and strong motion stations in the late 1980s and early 1990s. The TriNet project, 1997 to 2002, funded by FEMA, California OES, USGS, and other partners, increased the number of broadband and strong motion stations to 155 and significantly improved the data communications and processing infrastructure. The California Integrated Seismic Network (CISN) project of Caltech, CGS, USGS, and UC Berkeley (2001 to present) provides funds for continued operation of the SCSN, improved robustness, and migration of operations toward statewide processing.

The Southern California Earthquake Data Center (SCEDC), funded by the Southern California Earthquake Center (SCEC) and other sources, holds the complete data archives for SCSN/CISN from 1932 to present. The SCSN operates one IRIS/GSN station, PAS in Pasadena, California. If you use SCSN data, please include a citation to "Southern California Seismic Network operated by Caltech and USGS" in your work.
