GATR: Geophysics and Active Tectonics Research Group 

Our team of graduate and undergraduate researchers use seismic and potential fields methods, signal processing and geospatial tools to probe fundamental Earth processes. Our focus is magma-fault interactions within the crust and mantle at rifts and hotspots, both active and ancient. We use apply methods and results to explore hydrothermal potential and to evaluate earthquake and volcanic hazards.

The GATR lab is located in Stanley Thomas 417. Geophysical Equipment:  We have seven Nanometrics Meridian Posthole broadband (120s) and two Trillium compact seismometers with Taurus dataloggers.   Three NetRS GPS and Zephyr antennae are being used in campaign measurements to evaluate the rate of subsidence along passive margin normal faults.  Our PulseEkko Ground Penetrating Radar system has 50, 100, and 200 MHz antennae for archaeological and geophysical surveying.  A Geometrics magnetic gradiometer system is used in teaching and archaeological research.  Computing:  Students and researchers use the 8 large screen Mac and Linux workstations to analyze geophysical and geological data.  Owing to the large data volumes utilized, GATR has a Linux server and 32 Tb NAS data array, with a mirrored data archive.   Although most of the software we use is open source (e.g., ObsPy, SAC, PyLith, Seismic Handler Motif, Generic Mapping Tools), we also have licenses for Geosoft Oasis Montaj, EkkoProject, and 2D Move.
