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 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 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 کاملThe 2006–2007 Kuril Islands great earthquake sequence
[1] The southwestern half of a 500 km long seismic gap in the central Kuril Island arc subduction zone experienced two great earthquakes with extensive preshock and aftershock sequences in late 2006 to early 2007. The nature of seismic coupling in the gap had been uncertain due to the limited historical record of prior large events and the presence of distinctive upper plate, trench and outer r...
متن کاملEnergy release of the 2013 M(w) 8.3 Sea of Okhotsk earthquake and deep slab stress heterogeneity.
Earth's deepest earthquakes occur in subducting oceanic lithosphere, where temperatures are lower than in ambient mantle. On 24 May 2013, a magnitude 8.3 earthquake ruptured a 180-kilometer-long fault within the subducting Pacific plate about 609 kilometers below the Sea of Okhotsk. Global seismic P wave recordings indicate a radiated seismic energy of ~1.5 × 10(17) joules. A rupture velocity o...
