Broadband Seismology Facility

Broadband Seismology Facility at Yale

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 North Carolina, Virginia, West Virginia, and Ohio as part of the TEENA and MAGIC experiments, at Springfield Plantation, Dominica (station NATD), in Peru as part of the PULSE (PerU Lithosphere and Slab Experiment) project, and in southern New England as part of the Seismic Experiment for Imaging Structure beneath Connecticut (SEISConn). The stations are currently deployed in Massachusetts, New Hampshire, and Maine as part of the New England Seismic Transect (NEST). 

Here is a list of publications based on data collected using the Yale broadband instruments (see Publications page for links to .pdfs): Wagner et al., 2012; Eakin et al., 2014, 2015, 2016; Antonijevic et al., 2015, 2016; Scire et al., 2016, 2017; Kumar et al., 2016; Long, 2017; Deng et al., 2017; Bishop et al., 2017, 2018; Aragon et al., 2017; Bar et al., 2019; Long et al., 2019, 2020; Byrnes et al., 2019; Evans et al., 2019; Long and Aragon, 2020.
