The earthquake struck off the coast of Russia’s far-eastern Kamchatka Peninsula early Sunday morning local time, the United States Geological Survey also reported.

Tsunami threat over
The US National Tsunami Warning Centre had initially issued a tsunami threat. But later said the threat had passed. Local authorities never issued a tsunami alert.
Several aftershocks were recorded after the initial quake, but of lower intensity, the Kamchatka branch of Russia’s Unified Geophysical Service reported on its website.
The peninsula lies on a seismically active belt surrounding most of the Pacific Ocean known as the “Ring of Fire”. It is home to more than two dozen active volcanoes.
