Seismic Investigation of Newberry Volcano: In the summer of 2008 we deployed a seismic array across Newberry Volcano to image the magma system. Newberry is a large, recently active volcano; characterizing the size, depth, and percentage of melt in a magma-rich volume is critical for assessing the hazard posed by a volcano. We combine seismic tomography with finite difference waveform tomography to image the upper crustal magma structure (JGR 2012). We also combined teleseismic arrivals with active source refractions to perform a joint tomographic image (G3 2015; Publications listed below).
