Wednesday's magnitude 7.3 earthquake off Alaska's Aleutian Islands chain struck in a region that has experienced a handful of powerful quakes within the last five years.

A major earthquake with a preliminary magnitude of 7.3 initially triggered a tsunami warning for the southern Alaska Peninsula. It was later downgraded to an advisory.

The National Weather Service has lifted a tsunami advisory for communities on the Alaska Peninsula and Kodiak Island after a magnitude 7.3 earthquake struck about 55 miles south of Sand Point. The advisory was lifted at 2:43 p.m. Wednesday.
