Network Characteristics
The LCSN is operated by Lamont-Doherty Earth Observatory in cooperation
with the State University of New York at Potsdam, The University of Vermont,
Middlebury College (Vt), Westchester Community College, Rensselaer Polytecnic
Institute, the Adirondack Ecological Center, and the Delaware Geological
Survey/University of Delaware. The network operation is supported by the
National Earthquake Hazard Reduction Program (NEHRP) through the U. S.
Geological Survey.
Network Configuration
- 22 analog, short-period telemetry stations
- 2 broadband stations with direct digital recording
- 6 strong motion stations (5 with remote access)
- 10 USNSN broadband stations in monitoring region, received via VSAT
- Analog network data digitized by 4 Cutler/SUN systems, with data transfer
via internet.
- VDL operational, with Broadband station PAL.
- 2 additional digital broadband stations to be installed in 1998.
- Network covers an area 610 km from north to south and 220 km from east
to west.

Standard Earthworm Modules in current use
USGS Earthworm software (version 3) just installed (1998 March 4) on
SUN Ultra under Solaris 2.6. Earthworm module evaluation in process.
- Individual modules under implementation
Non-Standard Earthworm Modules in current use
- adcutler: input data from Cutler box into EW trace_ring. New module
written at LCSN.
Needs and future plan
- Time to evaluate EW software.
- EW modules to input Reftek DAS (cf. reftoew of UNR).
- EW modules to input USNSN data via VSAT (cf. nsn_rcv of U. Utah).
- EW modules to output waveform data into event-oriented SEED volumes.
- EW modules to output waveform data into network-day SEED volumes for
archieve.
- EW modules to feed input to CUBE rapid earthquake notification system.
- EW modules to send arrival times and locations to NEIC/USGS and CNSS
Composit Earthquake Catalog.
