News Analysis India — Fri, 28 Nov 2025 00:00:00 +0000

A powerful magnitude 6.0 earthquake jolted the Anchorage, Alaska, region on Thanksgiving morning, marking the most significant seismic event in south-central Alaska since 2021. The tremor struck at 8:11 a.m. local time, with its epicenter located approximately 7 miles northwest of Susitna, a community roughly 67 miles from the state’s largest city.

Authorities reported minimal immediate damage and no tsunami threat, attributing this to the earthquake’s moderate depth of 69 kilometers (43 miles). Anchorage Mayor Suzanne LaFrance confirmed via social media that municipal inspectors found no significant issues with major public infrastructure following the quake. The U.S. Tsunami Warning System swiftly confirmed that no tsunami would be generated.

The earthquake served as a stark reminder of Alaska’s frequent seismic activity, occurring on a holiday many playfully dubbed ‘Shakesgiving.’ This M6.0 event is the largest to affect the area since a M6.1 earthquake in 2021. Alaska consistently ranks as the most earthquake-prone state in the U.S. and is globally recognized for its high seismic activity, often experiencing magnitude 7 earthquakes annually.

The Kamchatka Peninsula in Russia experienced two earthquakes within a short span on Friday. The first tremor occurred at 12:28 AM Indian Standard Time, followed by a second at 12:38 AM. The initial earthquake registered a magnitude of 7.8 on the Richter scale, while the second measured 6. These seismic events prompted a tsunami alert due to the resulting high sea waves. Although no immediate damage has been reported, the situation is being closely monitored. The United States Geological Survey (USGS) located the epicenter of the first earthquake approximately 85 kilometers beneath the eastern coast of the Kamchatka Peninsula. The second quake’s epicenter was about 30 kilometers deep. According to Russia’s State Geophysical Service, the initial earthquake was a 7.8, followed by around five aftershocks. The US weather department issued a tsunami alert immediately after the quakes, urging people to stay away from coastal areas. This marks the third instance of tremors in Kamchatka within the past week. Previously, on July 29, 2025, a powerful 8.8 magnitude earthquake struck near the Kamchatka coast, considered one of the largest in the past decade, triggering alerts in several countries and leading to evacuations due to high waves.
