A monstrous 7.4 magnitude earthquake struck near Petropavlovsk-Kamchatsky, Russia, on July 20, terrorizing Kamchatka with violent shocks and a dramatic tsunami warning. Cameras captured apartments rattling wildly as at least five strong quakes rocked the region, all near a major fault where the Pacific and North American tectonic plates collide. After several powerful aftershocks, the tsunami threat was lifted by authorities, but residents remain shaken.
