Slab morphology, dehydration, and sub-arc melting beneath the Alaska Peninsula revealed by body-wave tomography

Sources of seismic data used to build VP and VS models from teleseismic double-difference tomography, and VP and VP/VS models from regional-scale double-difference tomography.

Arrival-time data of regional Alaska earthquakes recorded by global stations are archived at International Seismological Centre (2024), ISC-EHB dataset. Arrival-time data for regional stations are available from the Advanced National Seismic System’s Comprehensive Earthquake Catalog. Raw seismic data from regional stations are available at the Data Management Center of EarthScope Consortium under network IDs AK (Alaska Earthquake Center, Univ. of Alaska Fairbanks, 1987), AT (NOAA National Oceanic and Atmospheric Administration (USA), 1967), AV (Alaska Volcano Observatory/USGS, 1988), CN (Natural Resources Canada, 1975), GM (U.S. Geological Survey, 2016), II (Scripps Institution of Oceanography, 1986), NP (U.S. Geological Survey, 1931), TA (IRIS Transportable Array, 2003), and XO (Abers et al., 2018).
