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 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 کاملPrompt gravity signal induced by the 2011 Tohoku-Oki earthquake
Transient gravity changes are expected to occur at all distances during an earthquake rupture, even before the arrival of seismic waves. Here we report on the search of such a prompt gravity signal in data recorded by a superconducting gravimeter and broadband seismometers during the 2011 Mw 9.0 Tohoku-Oki earthquake. During the earthquake rupture, a signal exceeding the background noise is obs...
