Although large earthquakes generates strong shaking over a wide area, this is somewhat mitigated by the rupture being offshore. But if the rupture breaks the ocean floor, it generates destructive a tsunami that can spread across the ocean basin in the hours that follow.
Footage of the aftermath of the earthquake in Severo-Kurilsk is published by the Kamchatka branch of the Unified Geophysical Service of the Russian Academy of Sciences
