Characterizing the foreshock, main shock, and aftershock sequences of the recent major earthquakes in Alaska
Major earthquakes of M ≥7 are complex. The geometry, timing, and slip distribution of the complex nonlinear system of the lithospheric blocks-and-faults involved is usually not well resolved. Their rupture may propagate both upward into the crust and downward into the mantle. As a result, the expected ground shaking could be…
