Authorities canceled all tsunami advisories Monday night after first downgrading a tsunami warning for parts of Alaska's Aleutian Islands following a 7.9 magnitude earthquake.
Monday's quake generated small tsunamis, with waves of less than 7 inches, prompting the National Tsunami Warning Center to first downgrade the warning to an advisory.
Small waves were expected along parts of the Aleutian Islands stretching from Unimak Pass to Attu, and officials advised people to stay off the beaches.
The quake was widely felt in sparsely populated villages in an area about 1,400 miles southwest of Anchorage.
The earthquake recorded at 12:53 p.m. Alaska Daylight Time was centered about 13 miles southeast of Little Sitkin Island or 25 miles north Amchitka Island, an area prone to earthquakes located about 1,300 miles southwest of Anchorage.
There were several strong aftershocks, but no immediate reports of damage.
The largest city near the epicenter is Adak, which has about 300 residents.
