Fig. 6: Postseismic stress and frictional property estimates on the megathrust fault.

From: Tsunamigenic earthquake at the Sunda trench promoted by aseismic slip after a previous megathrust event

Fig. 6

Postseismic Coulomb stress characteristics on the megathrust. Black and pink stars show the 2007 Mw 8.4 Bengkulu and 2010 Mw 7.8 Mentawai earthquake, respectively. The orange contour presents the rupture patch of the 2007 event as shown in Figs. 1 and 2; the pinkish contours show the coseismic slip with a 2-m interval of the 2010 event as shown in Fig. 4a. Circles show aftershocks (Mw > 2.5) color-coded by time as shown in Figs. 1, 2 and 4, previously. Circles with light-pink outlines show relocated aftershocks after the 2007 event from ref. 36. Inset shows postseismic Coulomb stress at the large coseismic slip area of the 2010 event (two markers).
