Abstract
Body and surface wave tomography are two of the primary methods for estimation of regional scale seismic velocity variations. Seismic velocity is affected by temperature and rock composition in complex ways, but when combined with geologic and structural maps, relative temperature can in some cases be estimated. We present preliminary tomographic models for compressional and shear-wave velocity using local and regional earthquakes recorded by Earthscope Transportable Array stations, network stations operated by the Nevada Seismological Laboratory, and other stations of opportunity in the western Great Basin. Preliminary results show correlations with notable geologic structures in eastern California and western Nevada.
