The latest quake follows an 8.8 magnitude earthquake near the Kamchatka coast on Wednesday, which sparked a Tsunami that triggered emergency declarations in both Russia and the U.S.

The Kuril Islands stretch from the southern tip of Kamchatka Peninsula. Russian scientists had warned on Wednesday that strong aftershocks were possible in the region in the next several weeks.

A tsunami has hit coastal areas of Russia’s Kuril Islands and Japan’s large northern island of Hokkaido after a powerful, 8.8-magnitude earthquake off the coast of Russia early Wednesday.
