Abstract

We develop crust and mantle models of the Eastern Tennessee Seismic Zone (ETSZ) using imaging and inversion of the radial component P-wave transfer functions for stations in the Center for Earthquake Research and Information's (CERI) eastern Tennessee seismic network. We find complex structure in the upper 10 km in addition to an upper mantle high velocity zone with Vp values from ~8.2-8.56 km/s. This high velocity zone most likely extends from the west into the ETSZ and may be preserved mantle structure from the Granite Rhyolite province. Moho in the area is mostly gradational. However, velocity discontinuities can be seen at places indicating a fairly stable Moho depth of ~45-50 km. We suggest that the NY-AL lineament represents a major deep crustal to upper mantle feature.
