An earthquake of magnitude 4.5 occurred only 6 minutes ago 53 miles north of Anchorage, Alaska, the United States Geological Survey (USGS) reported.
The quake hit at a moderately shallow depth of 21 miles beneath the epicenter near Susitna North around noon on Thursday 26 November 2020 at 12.12 pm local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter. Weak shaking might have been felt in Susitna North (pop. 1,300) located 13 miles from the epicenter, Willow (pop. 2,100) 17 miles away, Talkeetna (pop. 900) 24 miles away, Trapper Creek (pop. 500) 24 miles away, Meadow Lakes (pop. 2,200) 25 miles away, Elmendorf Air Force Base (pop. 24,800) 48 miles away, Eagle River (pop. 24,800) 48 miles away, and Anchorage (pop. 298,700) 53 miles away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
