Seismic quiescence areas and the past large earthquakes. a Eight squares between 146 and 149°E are subfaults of the 1975 tsunami earthquake (Ioki and Tanioka 2016). Twelve squares between 148 and 152°E are subfaults of the largest aftershock of the 1963 Kurile earthquake (Ioki 2013). The subfaults in grey have a coseismic slip larger than 1 m. Three circles numbered as 1, 2, and 3 are the seismic quiescence areas on Additional file 1: Table S1. Red crosses show the epicenter of earthquake that occurred during times other than the seismic quiescence period within each area. The solid lines along the Kurile Islands indicate the trench axis (Bird 2003). b The coseismic slip of the 1969 Kurile earthquake (Ioki and Tanioka 2016) was compared with the seismic quiescence. The notation of symbols is the same as a
