[1] We image the rupture of the 28 March 2005 Sumatra Mw 8.6 earthquake by back-projecting teleseismic P waves recorded by the Global Seismic Network and the Japanese Hi-net to their source. The back-projected energy suggests that the rupture started slowly, had a total duration of about 120 s, and propagated at 2.9 to 3.3 km/s from the hypocenter in two different directions: first toward the north for 100 km and then, after a 40 s delay, toward the southeast for 200 km. Our images are… CONTINUE READING
