Summary
The Carib.Pwave.Harris.Miller.Porritt.2018 model incorporates broadband seismic data from 130 seismic stations deployed and maintained by multiple networks between 2000 to 2017. Data from 535 teleseismic earthquakes Mw>5.5 were to picked for P and PP to image the P wave velocity structure of the Caribbean mantle.

Data Set Description | [Harris et al., (2018)] The dataset includes the multi-frequency compression tomography model – relative P-wave velocity perturbations – for mantle structure beneath the Caribbean. The data used for the P wave model includes ~20,000 manually measured traveltime residuals, which reflect the difference between observed traveltimes and values predicted using the radially symmetric iasp91 global velocity model. 17,491 were measured from teleseismic P waves and 1,638 were measured from teleseismic PP waves. |
