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 — including one that shook communities almost exactly two years earlier.

The quake that struck Alaska’s southern coast on Wednesday, July 16 is part of a larger sequence that may continue to unfold in destructive ways.

A magnitude 7.3 earthquake struck Alaska on Wednesday afternoon and a tsunami warning was canceled two hours later for the Alaska Peninsula and Kodiak Island.
