Intraplate and interplate faulting interactions during the August 31, 2012, Philippine Trench earthquake (Mw 7.6) sequence
[1] On August 31, 2012, a large (Mw 7.6) thrust earthquake occurred within the subducting Philippine Sea plate seaward of a low seismicity region of the plate boundary (9.5 N– 11.5 N), possibly as a result of horizontal compressional stress accumulation offshore of a locked megathrust. The mainshock ruptured from 30–50 km depth, with high radiated-energy/seismic-moment ratio and enriched shortp...
متن کاملThe 1999 M w 7 . 1 Hector Mine , California , Earthquake Sequence : Complex Conjugate Strike - Slip Faulting
The 1999 Mw 7.1 Hector Mine mainshock showed right-lateral strikeslip faulting, with an initial strike of N6 W and vertical dip. The mainshock was preceded within 20 hours by 18 recorded foreshocks of 1.5 M 3.8 within a few kilometers distance of the mainshock hypocenter. The aftershocks delineate how the Hector Mine earthquake ruptured with strike N6 W to the south for a distance of 15 km, and...
متن کاملSource rupture process of the 2016 central Tottori, Japan, earthquake (MJMA 6.6) inferred from strong motion waveforms
The source rupture process of the 2016 central Tottori, Japan, earthquake (MJMA 6.6) was estimated from strong motion waveforms using a multiple-time-window kinematic waveform inversion. A large slip region with a maximum slip of 0.6 m extends from the hypocenter to the shallower part, caused by the first rupture propagating upward 0–3 s after rupture initiation. The contribution of this large ...
متن کاملEarthquake in a maze: compressional rupture branching during the 2012 M(w) 8.6 Sumatra earthquake.
Seismological observations of the 2012 moment magnitude 8.6 Sumatra earthquake reveal unprecedented complexity of dynamic rupture. The surprisingly large magnitude results from the combination of deep extent, high stress drop, and rupture of multiple faults. Back-projection source imaging indicates that the rupture occurred on distinct planes in an orthogonal conjugate fault system, with relati...
متن کاملNonlinear dynamic rupture inversion of the 2000 Western Tottori, Japan, earthquake
[1] We have developed a systematic nonlinear inversion method for estimating rupture propagation and the underlying dynamic parameters for large historical earthquakes. The rupture modeling is carried out using a three-dimensional finite-difference method, and the inversion is implemented by a neighbourhood algorithm, minimizing the misfit between computed and observed near-fault seismograms. W...
