A tsunami source inversion analysis has been carried out to estimate static crustal deformation associated with the 2011 off the Pacific Coast of Tohoku Earthquake. We use the Mansinha and Smylie's(1971) analytical solution for the displacements of inclined faults to estimate the slip distribution so that the crustal deformation at each observation site coincides with the displacements calculated from 40 and/or 60 subfaults of 20×20 km2. The maximum slip displacement reaches to 50m at the location about 50km away from the epicenter. Tsunami waveformes are calculated with the fault model assuming a constant rise time of 20s on each subfault and a rapture velocity of 2 km/s. The tsunami waveforms are similar to those of Fujii and Satake simulation which is tsunami waveform inversion with pressure and GPS wave gauge data.
