NSAM slab geometry files

The study presents a new 3-D offshore geometry of the Nazca-South AMerica (NSAM) subduction interface off western South America based on a comprehensive compilation of offshore active seismic data. We use 66 multi-channel, and 30 wide-angle seismic profiles acquired from Colombia (4°N) to southern Chile (46°S), covering a margin-length of 6,000 km, to generate a high-precision mesh (± 0.5 km).
