Peak horizontal ground velocity across the main Japanese islands for a 2010 Mw 6.8 at 578 km depth near the Russia/China border close to Vladivostok, b 2015 Mw 7.9 Ogasawara event at 680 km depth and c 2012 Mw 7.7 event off Sakhalin at 598 km depth. The location of each event is indicated with a blue star. The K-NET and KiK-net strong motion stations that recorded ground motions are marked by triangles. Iso-depth contours for the subducting Pacific slab are shown by broken lines, and plate boundaries are marked by blue lines
