Rupture modes in laboratory earthquakes: Effect of fault prestress and nucleation conditions
Rupture modes in laboratory earthquakes fault prestress nucleation conditions
2014/4/8
Seismic inversions show that earthquake risetimes may be much shorter than the overall rupture duration, indicating that earthquakes may propagate as self‐healing,pulse‐like ruptures. Several mechanis...
