Alaska cross section from the 2023 NSHM

A cross section through the area of Anchorage, AK showing earthquakes at depths along with subduction model linework from Slab2 and inputs from the 2007 NSHM. The image shows the seismic catalog (for the 2023 NSHM seismic hazard model for Alaska; Powers and others, 2024) for the crust (yellow), interface (orange), and intraslab (red). Depths to the top of the subducting Pacific slab from Slab2 (Hayes et al., 2018) shown in purple to green linework for depths up to 180 km. Note the simplified linework from 2007 showing the shallower geometry of the Prince William Sound section (green) compared with the geometry from 2023 (blue).
