Tomographic Imaging of Slab Segmentation and Deformation in the Greater Antilles

Harris, Cooper W.; Miller, Meghan; Porritt, Robert

Description

We present a new tomographic P wave model of the upper mantle in the east Caribbean region. The model was built using 3-D finite frequency sensitivity kernels and ~20,000 teleseismic P and PP traveltime residuals from 535 events recorded across 130 broadband seismometers. We observe high-velocity features corresponding to a Caribbean beneath northern South America and an arcuate slab beneath the Lesser and Greater Antilles island arcs. The latter exhibits an along strike gradient in dip with...[Show more]
