Magnitude 7.5 Earthquake Off Alaskan Coast 36

This morning at 08:58 UTC a magnitude 7.5 earthquake struck off the coast of southeastern Alaska. The depth was just shy of 10km. The quake occurred roughly 106km from the city of Craig and about 341km from the capital city of Juneau. A tsunami warning was issued shortly after the quake, but later canceled when it became apparent that sea level changes would be minor, with no widespread destructive wave. The observed tsunami was no more than six inches high. The earthquake was felt on land, shaking houses and tossing objects to the floor, but as yet there are no reports of injuries. The U.S. Geological Survey said, 'At the location of this earthquake, the Pacific plate is moving approximately northwestward with respect to the North America plate at a velocity of 51 mm/yr. This earthquake is likely associated with relative motion across the Queen Charlotte fault system offshore of British Columbia, Canada, which forms the major expression of the Pacific:North America plate boundary in this region. The surrounding area of the plate boundary has hosted 8 earthquakes of magnitude 6 or greater over the past 40 years."
