Short Description   The model incorporates P and PP picks from 90 seismic stations deployed and maintained by multiple networks between 2010 to 2018 including the temporary deployment of 30 broadband stations (YS network). Data from teleseismic earthquakes Mw>5.5 were used to image the P wave velocity structure of the Banda Arc mantle.

Data Set Description [Harris et al., 2020 ] The dataset includes the multi-frequency compression tomography model – relative P-wave velocity perturbations – for mantle structure beneath Eastern Indonesia. Our data set consists of ~20,000 arrival times of teleseismic P and PP waves recorded across Indonesia. Manually picked P and PP arrival times from 207 events recorded across the YS network of 31 broadband stations (Miller et al., 2016) between 2014 and 2017 for a total of 9,838 traveltime residuals. In addition, 10,117 automatically picked arrivals from 339 events recorded across 59 stations from the AU, IA, and II broadband seismic networks between 2010 and 2018 were incorporated.
