CURRENT PROJECTS

The Global Seismology and Tectonics Group is involved in broadband seismology studies of earthquake source rupture properties and the large-scale structure of orogenic systems. Broadband (passive-source) seismology utilizes naturally occurring earthquakes to image large-scale lithospheric structures (crustal and lithospheric thickness, major crustal and mantle interfaces, lateral wavespeed variations, crustal and mantle anisotropy related to fabrics and flow). These experiments typically involve field deployments for one to two years of 40-60 broadband instruments in a 2D array with station spacing of tens of kilometers over areas of hundreds of kilometers. We have five ongoing projects: Wyoming, SIEMBRA, NAF, Batholiths, and SNEP.
