Earthquakes in the shadows: Why aftershocks occur at surprising locations
Jeanne L. Hardebeck, Ruth A. Harris
2022, The Seismic Record (2) 207-216
For decades there has been a debate about the relative effects of dynamic versus static stress triggering of aftershocks. According to the static Coulomb stress change hypothesis, aftershocks should not occur in stress shadows—regions where static Coulomb stress has been reduced. We show that static stress shadows substantially influence aftershock...
