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…
NW/SE and NNW/SSE faults show higher slip tendency
What the study found NW/SE- and NNW/SSE-oriented faults near the selected study area showed higher slip tendency, meaning they were assessed as more susceptible to reactivation. The authors also identified some faults with both above-average slip tendency and potential moment magnitude. Why the authors say this matters The study suggests this information is relevant for…
