We present two new seismic velocity models for Alaska from joint inversions of body-wave and ambient-noise-derived surface-wave data, using two different methods. Our work takes advantage of data from many recent temporary seismic networks, including

The Southern Alaska Lithosphere and Mantle Observation Network (SALMON) is a deployment of 28 broadband, direct‐burial posthole seismometers in the Cook Inlet region of the southern Alaska subduction zone. Here we describe the objectives of the pro
