The Lamont Cooperative Seismographic Network (LCSN)

English Abstract:

The Lamont Cooperative Seismographic Network (LCSN) consists of 35 broadband seismographic stations and an additional half dozen short-period stations. Stations located in New York, New Jersey, Connecticut, Pennsylvania, Delaware, Maryland, Vermont and New Hampshire, are operated by 40 cooperating partners, with Lamont Doherty Earth Observatory (LDEO) serving as the lead institution. Partners include colleges and universities, community colleges, secondary schools, museums, a state geological survey, conservation organizations, research institutes, and a tourist attraction. The LCSN offers unique educational opportunities for students at a variety of levels, for public officials, and for the general public.

The LCSN serves as one of seven regional seismic monitoring and data center for the Advanced National Seismic System (ANSS) led by US Geological Survey. The backbone of the LCSN real time data acquisition for earthquake monitoring in the northeastern US is the Internet based Earthworm system with the back-end using the ANSS Quake Management System (AQMS) software. All seismogram data acquired by LCSN are archived at the IRIS-DMC in Seattle, Washington in real time, while much of the earthquake data such as catalogs, maps, recent earthquakes, felt reports (Did-You-Feel-It?), and event waveform data are hosted on our website: http://www.ldeo.columbia.edu/LCSN.

The LCSN modernized most of its seismic hardware in 2011 and has continued a strong program of station improvements for greater data availability and quality. We share resources with our partners to minimize costs for telemetry by using their high speed internet, and recently sharing a county’s microwave Emergency Management link. Along with these improvements, we continue to test and upgrade with more reliable power and backup systems for our solar-powered stations.
