The first seismic waves from a magnitude 6.4 subduction zone earthquake offshore from Umnak Island arrived at Yellowstone at 0929-0930. The first waves from a magnitude 5.7 quake south of Patton Seamount (= way offshore from southern Alaska) arrived at Yellowstone at 0941. See: https://www.flickr.com/photos/jsjgeology/50669165681 |
