Effects of Rupture Processes in an Inverse Analysis of the Tsunami Source of the 2011 Off the Pacific Coast of Tohoku Earthquake

摘要

An inverse analysis of the tsunami source of the 2011 earthquake off the Pacific coast of Tohoku (Mw 9.0) was conducted on the basis of offshore sea-level observation near the source area. The effects of the rupture process on tsunami source inversion were investigated by comparing tsunami source models that assumed either infinite or finite rupture velocities.
