Large fault slip peaking at trench in the 2011 Tohoku-oki earthquake
During the 2011 magnitude 9 Tohoku-oki earthquake, very large slip occurred on the shallowest part of the subduction megathrust. Quantitative information on the shallow slip is of critical importance to distinguishing between different rupture mechanics and understanding the generation of the ensuing devastating tsunami. However, the magnitude and distribution of the shallow slip are essentiall...
متن کاملElectronic Supplement to : Low friction along the high slip patch of the 2011 Mw 9 . 0 Tohoku - Oki earthquake
The objective of this Electronic Supplement is to present in a concise manner the kinematic approach of limit analysis for fluid saturated media as proposed in details by Leroy and Pons (2012). The limit analysis approach [Chandrasekharaiah and Debnath, 1994; Salençon, 2002] is based on the principle of virtual powers and the theorem of maximum rock strength [Maillot and Leroy, 2006]. The metho...
متن کاملFrictional properties of incoming pelagic sediments at the Japan Trench: implications for large slip at a shallow plate boundary during the 2011 Tohoku earthquake
The 2011 Tohoku earthquake (Mw 9.0) produced a very large slip on the shallow part of a megathrust fault that resulted in destructive tsunamis. Although multiple causes of such large slip at shallow depths are to be expected, the frictional property of sediments around the fault, particularly at coseismic slip velocities, may significantly contribute to large slip along such faults. We have thu...
متن کاملHydro-Acoustic Wave Generation during the Tohoku-Oki 2011 Earthquake
We investigate the surface gravity and hydro-acoustic wave fields, generated by the 2011 Tohoku-Oki tsunamigenic event using a numerical model based on a computationally efficient depth-integrated equations for a compressible water column coupled to a dissipative sedimentary layers. Spectral analysis of bottom pressure time series obtained in deep water revealed the role of underlying layer on ...
