Hydro-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 ...
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...

متن کاملSensitivity of tsunami wave profiles and inundation simulations to earthquake slip and fault geometry for the 2011 Tohoku earthquake
In this study, we develop stochastic random-field slip models for the 2011 Tohoku earthquake and conduct a rigorous sensitivity analysis of tsunami hazards with respect to the uncertainty of earthquake slip and fault geometry. Synthetic earthquake slip distributions generated from the modified Mai-Beroza method captured key features of inversion-based source representations of the mega-thrust e...
متن کاملDisplacement above the hypocenter of the 2011 Tohoku-Oki earthquake.
The moment magnitude (M(w)) = 9.0 2011 Tohoku-Oki mega-thrust earthquake occurred off the coast of northeastern Japan. Combining Global Positioning System (GPS) and acoustic data, we detected very large sea-floor movements associated with this event directly above the focal region. An area with more than 20 meters of horizontal displacement, that is, four times larger than those detected on lan...
