Russian agencies have warned a new powerful earthquake near the Pacific's Kuril Islands could trigger a tsunami wave up to 19 centimeters (7.5 inches). A magnitude 6.8 earthquake hit Russia's Kuril islands on Sunday, according to data from the U.S. Geological Survey (USGS). The Pacific Tsunami Warning System gauged the quake at 7.0.

Both incidents could be connected to the huge earthquake that rocked Russia’s Far East last week, that triggered tsunami warnings as far away as French Polynesia and Chile, and was followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka peninsula.

A powerful earthquake and a rare volcanic eruption shook Russia's Kamchatka Peninsula and the Kuril Islands, prompting tsunami warnings and raising concerns among emergency officials and seismologists.
