Early magnitude and potential damage zone estimates for the great Mw 9 Tohoku-Oki earthquake
[1] The Mw 9.0, 2011 Tohoku-Oki earthquake has reopened the discussion among the scientific community about the effectiveness of earthquake early warning for large events. A well-known problem with real-time procedures is the parameter saturation, which may lead to magnitude underestimation for large earthquakes. Here we measure the initial peak ground displacement and the predominant period by...

متن کاملSubevent location and rupture imaging using iterative backprojection for the 2011 Tohoku Mw 9.0 earthquake
S U M M A R Y Knowledge of the rupture speed and spatial–temporal distribution of energy radiation of earthquakes is important for earthquake physics. Backprojection of teleseismic waves is commonly used to image the rupture process of large events. The conventional backprojection method typically performs temporal and spatial averaging to obtain reliable rupture features. We present an iterati...
متن کاملDynamic rupture of the 2011 Mw 9.0 Tohoku-Oki earthquake: Roles of a possible subducting seamount
[1] Using a hybrid MPI/OpenMP parallel finite element method for spontaneous rupture and seismic wave propagation simulations, we investigate features in rupture propagation, slip distribution, seismic radiation, and seafloor deformation of the 2011 Mw 9.0 Tohoku-Oki earthquake to gain physical insights into the event. With simplified shallow dipping (10 ) planar fault geometry, 1D velocity str...
متن کاملThe 2011 Tohoku earthquake and devastating tsunami.
At 14:46 on March 11, 2011, the magnitude-9.0 earthquake attacked Sendai and neighboring cities distributed along the northeast coast of Honshu Island, Japan. Its epicenter is located 130 km east of Sendai (Fig. 1). Unfortunate ly, the strong earthquake generated devastating tsunamis that destroyed many towns and villages near the seashore in Iwate, Miyagi, and Fukushima prefectures. The natura...
