In late 2008, the Geology and Geophysics department acquired a pool of 21 broadband seismometers for use in temporary deployments in regions of particular tectonic interest. Each set consists of a Trillium 120P broadband sensor along with a Taurus digitizer/datalogger; the equipment is manufactured by Nanometrics, Inc.

This equipment has been deployed in the past in New England (station EARL, located in South Berwick, ME), in North Carolina, Virginia, West Virginia, and Ohio as part of the TEENA and MAGIC experiments, at Springfield Plantation, Dominica (station NATD), and in Peru as part of the PULSE (PerU Lithosphere and Slab Experiment) project. The stations are currently deployed in Connecticut as part of the Field Experiences for Science Teachers (FEST) pilot program - stay tuned for updates!
