Quick Analysis
According to the epicenter of the quake, this is an underwater quake. Based on the hypocenter, an underwater landslide is conceivable and could trigger a tsunami. Based on the data received, using the depth of the hypocenter, a potential tsunami will reach the nearest (Petropavlovsk-Kamchatsky, Kamtsjatka, Russia) settlement within 03:30.
