Alaska [US], July 22 (ANI): A strong earthquake measuring 6.3 struck off the East Coast of Kamchatka on Tuesday, the National Center for Seismology (NCS) reported.
According to the NCS, the earthquake occurred at 7:30 a.m. Indian Standard Time, at a depth of 50 kilometers.
“EQ of M: 6.3, On: 22/07/2025 07:29:38 IST, Lat: 52.50 N, Long: 160.53 E, Depth: 50 Km, Location: Off East Coast of Kamchatka,” the NCS wrote on X.
The agency noted that the location of the earthquake was approximately 1,550 kilometers west of the Andreanof Islands, Alaska.
The Kamchatka Peninsula sits at the junction of the Pacific and North American tectonic plates, making it a seismic hot zone. Shallow earthquakes, like this one, are generally more dangerous than deep earthquakes because the seismic waves have less distance to travel to the surface, resulting in stronger ground shaking, potentially more damage to structures, and higher casualties.
Previously, a tsunami warning was issued for parts of coastal Alaska following an earthquake in the Gulf of Alaska, according to the U.S. Tsunami Warning System, The New York Times reported.
A tsunami warning is the most urgent alert issued by the National Weather Service, indicating people should move to higher ground or go inland immediately. A tsunami advisory urges people to leave coastal waters and avoid beaches and waterways, while a tsunami watch means experts are still evaluating the threat and further information will follow.
The Alaska-Aleutian subduction system is among the most seismically active regions in the world, producing more magnitude-8 or greater earthquakes over the past century than any other area. Many of these earthquakes, as well as coastal and submarine landslides, have generated tsunamis.
The region also contains over 130 volcanoes and volcanic fields, accounting for more than three-quarters of U.S. volcanoes that have erupted in the past 200 years. (ANI)
