Fig. 7

Static stress changes from Mw 7.6 event for north dipping plane of the Mw 7.4 event. Star indicates the epicenter of the Mw 7.4 event. The narrow rectangle panel is the surface projection of the fault plane of Mw 7.6 event and the wider rectangle is the Mw 7.4 north dipping fault plane. The thicker line of the rectangles shows the upper edge of the dipping planes. a–d are the static stress changes for different depths and all depths show a strong increase around the hypocenter of the Mw 7.4 event
