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 Survery/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 Data
Access & Archive section and downloading via ftp. Arrival
times of the seismic phases are also available on this web site.
Waveform data that are not on the list can be requested by E-mail and
the data will be sent to interested people via Internet and
E-mail.
We encourage K through grade 12 students, teachers and
public to use this and other similar web sites to learn more about the
earthquakes around the area they live and other parts of the world.
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) and more information on regional seismographic networks
in the United States and recent earthquakes can be found on
USGS.
