Network Data Availability



The Lamont-Doherty Cooperative Seismographic Network (LCSN) monitors earthquakes that occur primarily in the northeastern United States. The goal of the project is to compile a complete earthquake catalog for this region to assess the earthquake hazards, and to study the causes of the earthquakes in the region. The LCSN now operates 40 seismographic stations in seven states: Connecticut, Delaware, Maryland, New Jersey, New York, Pennsylvania and Vermont.

LCSN is unusual in using a variety of station operators (college & university faculty, secondary school teachers, museums, etc.) to engage a wide variety of audiences and to reach out to large numbers of the general public. It also provides professional development and improved awareness among station operators who are not professional seismologists. About half of the broadband station operators and stations belong to each participating organization. Hence, a large portion of the operation and maintenance cost are born by the participating organizations. A list of ~35 partners are listed below. The LCSN relies upon their support in station maintenance and operation in the region. The organizations who operate LCSN stations consist of 2 secondary schools, 2 environmental research and education centers, 3 state geological surveys, a museum dedicated to Earth system history, 2 public place (Central Park, NYC & Howe Caverns), 3 two-year colleges, and 15 four-year universities.

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.
