There were no immediate reports of damage or injuries, but shaking was felt across the southcentral area of Alaska.

The earthquake felt like “a heavy dump truck” riding the street, Anchora resident Linda Lee Covert wrote as a Facebook comment to a local news outlet. She said that the ground shook for good “15-20 seconds.” Others noted that it started “small and just got bigger.”

Meanwhile in Willow, Becky Walter told Alaska Dispatch News that she thought “a moose was head butting my camper.”

Dozens of earthquakes occur daily in Alaska, as the northern state lies in the region where the Pacific plate subducts beneath the North America plate. The 3,000 km Aleutian arc stretches from the Gulf of Alaska in the east to the Kamchatka Peninsula in the west, making the zone prone to destructive earthquakes and tsunamis. Since the 20th century, this region was shaken by twelve large earthquakes of a 7.5 magnitude or higher.
