Fault heterogeneity and restrengthening explain Tohoku-Oki rupture complexity
What the study found The study finds that the complex rupture of the 2011 Tohoku-Oki megathrust earthquake can arise spontaneously from rapid coseismic frictional restrengthening and fault heterogeneity. The authors report that dynamic stress redistribution with episodic rupture reactivation can produce mixed downdip pulse-like and updip crack-like rupture. Why the authors say this matters The…
