Abstract:
|
Teleseismic and GPS data were jointly
inverted for the rupture process of the 2011 Tohoku earthquake. The inversion
results show that it is a bilateral rupture event with an average rupture
velocity less than 2.0 km/s along the fault strike direction. The source rupture
process consists of three sub-events, the first occurred near the hypocenter and
the rest two ruptured along the updip direction and broke the sea bed, causing a
maximum slip of about 30 m. The large-scale sea bed breakage may account for the
tremendous tsunami disaster which resulted in most of the death and missing in
this mega earthquake. |
