Displacement 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...
متن کاملLarge-scale Simulation of Seismic-wave Propagation of the 2011 Tohoku-oki M9 Earthquake
We describe a large-scale simulation of the seismic wave propagation from the 2011 Tohoku-Oki earthquake. We combine structure models for topography, sediments, crust and subducting plates to construct a 3D structure model for the northeastern Japan area. Then we simulate the near-field wave propagation by using a FDTD method which is accelerated by the use of multi-GPUs (Graphics Processing Un...

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 ...
متن کاملProperties of GPS noise at Japan islands before and after Tohoku mega-earthquake
The field of 3-components GPS signals is analyzed for the network of 1203 stations at the Japanese islands from January 30 up to March 26, 2011. This time interval includes just over 40 days of observation before the Tohoku mega-earthquake on March 11, 2011 (M = 9.0) and nearly 16 days of observation following this event. The signals from each station are three-component time series with time s...
