Prasad 12 April 2012 Tectonic setting Strike-slip tectonics Wharton Basin The 2012 earthquake's epicenter was located within the Indo-Australian plate, which is divided into two sub- or proto-plates: the Indian, and Australian. At their boundary, the Indian and Australian plates converge at 11 mm in 1 on per year in a NNW–SSE direction. This convergence is accommodated by a broad zone of diffuse deformation. As part of that intraplate deformation, north–south trending fracture zones have been reactivated from the Ninety East Ridge as far east as 97°E.Kreemer C.

A process which would eventually split the Indo-Australian plate in two probably started 8 to 10 million years ago and is still taking place.

It was felt as far away as Malaysia, the Maldives and in India. The earthquake was caused by a strike-slip motion.

Since 2006 there have been three other earthquakes in the area with a similar faulting style. All these earthquakes were consistent with either left-lateral slip on SSW–NNE orientated strike-slip faults, or right-lateral slip on WNW–ESE orientated strike-slip faults, both compatible with the direction of convergence.ftp://hazards.cr.usgs.gov/maps/sigeqs/20120411/20120411.pdf Poster of the M8.6 Northern Sumatra, Earthquake of 11 April 2012 United States Geological Survey 11 April 2012 https://web.archive.org/web/20220121035946/ftp://hazards.cr.usgs.gov/maps/sigeqs/20120411/20120411.pdf 2022-01-21 dead 12 April 2012 A back projection analysis of data collected by Hi-net, an observation network in Japan, found a complex pattern of four conjugate faults.

The rupture of these earthquakes occurred on multiple, almost orthogonal faults. This is rare in a single earthquake. This earthquake had an overall relatively slow rupture speed, although the speed was above the S-wave velocity in some fault segments. The rupture may have affected the crust and the upper mantle according to the kinematic source inversion.http://www.ipgp.fr/pages/040119.php?langue=0 Séismes au large de Sumatra mercredi 11 avril 2012 Institut de Physique du Globe de Paris 9 February 2013 fr https://web.archive.org/web/20130624151105/http://www.ipgp.fr/pages/040119.php?langue=0 24 June 2013 dead The rupture was caused by ductile shear heating instability which is different from frictional failure and operates between 600 - 800 C, which corresponds to about the depths of 40-60 km on. The serpentinization of oceanic lithosphere can lead to a low friction coefficient, but the reaction is possible only up to 400 - 500 C, which corresponds to the depth of about 25 km on. A single dynamic weakening mechanism which can work over the whole range of slip of this earthquake is still to be identified.http://web.gps.caltech.edu/~tsai/files/Meng_etal_Science2012All.pdf Earthquake in a Maze: Compressional Rupture Branching During the 2012 Mw 8.6 Sumatra Earthquake L.
