This study investigates four different past earthquake scenarios associated with tsunami events. The red and yellow rectangles represent the projected earthquake dimensions, locations, and orientations retrieved by the proposed inverse model for acoustic radiation. The analyzed earthquakes are: a) Sept. 29, 2009, Mw 8.1, SSW of Matavai, Samoa; b) Dec. 21, 2010, Mw 7.4, Bonin Islands, Japan region; c) March 14, 2012, Mw 6.9, SSE of Kushiro, Japan; and d) Oct. 25, 2013, Mw 7.1, off the east coast of Honshu, Japan. The model delivers two potential fault orientations for each earthquake scenario, which are numerically modeled and compared.
