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 significant earthquake, initially reported at a magnitude of 6.7, struck Russia's Kuril Islands. The magnitude was later updated to 7 by the U.S. Geological Survey and the Pacific Tsunami Warning System.
