Russia on Tuesday woke up to a powerful 7.7 magnitude earthquake that hit 685 km in Petropavlovsk-Kamchatskiy coast line raising tsunami warnings in the region.

The earthquake occurred at 05:04 AM (local time) with Kamchatka Krai peninsula being the epicentre.

The quake followed several other aftershocks ranging to 1.2 to a couple above 5.0 magnitudes before simmering down.

The authorities have issued warnings of a possible tsunami for the coastal areas within 300 km of the region.

“Based on preliminary earthquake parameters… hazardous tsunami waves are possible for coasts located within 300 km (186 miles) of the earthquake epicentre,” said officials.

No reports of loss of lives or property have been reported from the area that is sparsely populated, indicating low human impact.

Earlier in the day, another quake of the magnitude of 6.2 was recorded in the area.

The authorities have asked the locals to stay away from the coastal best until more information is issued.
