Tsunami alerts cancelled

ANCHORAGE, Alaska—All tsunami advisories have been cancelled following a magnitude-7.9 earthquake in Alaska’s Aleutian Islands.
The U.S. National Tsunami Warning Center cancelled the last remaining advisory late yesterday afternoon.

At one point, areas stretching from Attu to Unimak Pass were under a tsunami warning or advisory, but the largest reported wave was about 18 cm.
The advisory area included Unalaska, a community of about 4,000 people and home to Dutch Harbor—one of the nation’s largest fishing ports.
Emergency Measures British Columbia said there was no threat to other U.S. or Canadian areas along the North American Pacific coast.
The quake struck yesterday afternoon and was widely felt in sparsely-populated villages in an area about 1,400 miles southwest of Anchorage.
The earthquake initially was measured at magnitude 8.0.
But scientists have downgraded that to 7.9 after having time to review the data.
