Every new earthquake near Japan appears here the moment it is detected - watch an aftershock sequence unfold, with optional browser alerts. No app, no setup.
After a major earthquake in Japan, the ground keeps moving: aftershocks are smaller quakes triggered as the crust adjusts around the fault that ruptured. They are most frequent right after the mainshock and taper off over days to months. This page tracks recent seismic activity across Japan live, so you can follow an aftershock sequence as it happens. For instant alerts the moment a new aftershock strikes near you, the free QuakeMate earthquake alert app sends real-time push notifications.
