At 1:55 am (AKDT), an earthquake struck about 70 km southeast of Amukta Pass, Alaska. The preliminary rating for the quake was 7.1, but was later downgraded by the U.S. Geological Survey (USGS).
According to the USGS, there are no initial reports of injuries or damage as the areas affected are very remote and not heavily populated.
A tsunami warning was issued for coastal areas from Unimak Pass to Amchitka Pass following the quake, but was cancelled about an hour later.
A bulletin issued by the West Coast and Alaska Tsunami Warning Center said no destructive tsunami was recorded and no tsunami danger existed along the coasts of the U.S. west coast states, Alaska, and British Columbia.
In June, a 7.2 magnitude earthquake struck in the same area of the Aleutians in Alaska. It also prompted a tsunami warning, but no casualities or tsunamis were reported.
