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.

A powerful earthquake off Russia’s east coast triggered tsunami waves across the Pacific, prompting alerts in Hawaii and California.

Several warnings were downgraded on Wednesday in various areas that faced the threat of tsunamis after a magnitude 8.8 earthquake that struck near Russia late Tuesday.
