A 7.1 magnitude earthquake struck Friday in the Aleutian Islands off Alaska, the U.S. Geological Survey reported, prompting a brief tsunami warning for a portion of Alaska’s coast.

The U.S. Geological Survey said the earthquake struck in the waters at about 6:55 a.m. ET. There were no reports of injuries or damage, according to Alaska’s KTUU.com.

The tsunami warning was in effect for coastal areas of Alaska from Unimak Pass to Amchitka Pass. It was canceled about an hour later, USGS confirmed to NBC News.

The areas are very remote and not heavily populated, according to Jessica Sigala, a geophysicist with the USGS in Golden, Colo.

The quake struck 107 miles southeast of Atka, Alaska, at a depth of 22.1 miles.

This is the second large earthquake in the Aleutian Chain this summer. In June, a 7.2 magnitude quake in the same area also prompted a short tsunami warning, according to KTUU.
