A strong 7.7 magnitude earthquake has struck Komandorskie Ostrova region of Russia, triggering a tsunami warning for that nation’s coast. According to US Geological Survey, the major earthquake that hit Russia was originally recorded as 7.4 magnitude, but it has been upgraded to magnitude 7.8 magnitude on the richter scale. The earthquake was followed by several aftershocks hit the northern Pacific Ocean between the tip of the Aleutian Islands and Russia’s Kamchatka Peninsula.

Following the powerful earthquake in Russia, the US Pacific Tsunami Warning Centre has issued warning saying people located in coastal areas should stay alert and wait for further information. “Based on preliminary earthquake parameters… hazardous tsunami waves are possible for coasts located within 300 km (186 miles) of the earthquake epicentre,” said the US Pacific Tsunami Warning Centre.

The National Weather Service said, “Hazardous tsunami waves are forecast for some coasts.” Tsunami waves were possible for coasts within 186 miles of the earthquake epicenter, according to reports.
