The Pacific Tsunami Warning Center issued a warning for Russia’s Kamchatka Peninsula after two major quakes struck the sea nearby on a Sunday.

The bigger quake was said to be of magnitude 7.4 and was at a depth of 12 miles and 89 miles east of the city. This was said to have had a population of 180,000.

A few minutes before, a quake with a magnitude of 6.7 was recorded nearby. At the start, the American National Weather Service shared a warning for Hawaii, but this was later canceled after further investigation indicated there is no longer a threat to the island.

Russia’s state-run TASS news agency went into details about how waves of up to 60 cm could hit the sparsely populated Aleutsky District on the Commander Islands.

Waves of up to 40 cm could impact the Ust-Kamchatsky area in the eastern Kamchatka, which is said to be the most populated area in the southeastern part of this peninsula and home to the regional capital.

These might end up seeing waves that go as high as 15 cm. A message shared on the Pacific Tsunami Warning Center said these tsunami waves hit 1 meter above tide level as much as possible for some Russian coasts.
