ANCHORAGE, Alaska (AP) — Communities along a 700-mile stretch of Alaska’s southern coast ordered residents to higher ground after a powerful offshore earthquake Wednesday, but officials quickly downgraded and then canceled a tsunami warning for the region. There were no reports of significant damage..

A rare tsunami warning was issued for part of Alaska’s coast after a magnitude 7.3 earthquake struck near Sand Point in the Aleutian Islands.

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.

Calling it an exercise in imagination, seismologist Carl Tape stopped at the site of Dome City and the former townsite of Meehan 113 years after a 7.2 magnitude earthquake struck the area.

Scientists in the US have said that a 100-foot ‘doomsday’ mega tsunami could wipe out the entire western seaboard. The wave could come from the Cascadia Subduction Zone, which is a 700-mile fault line from northern California in the USA to British Columbia in Canada that has laid dormant for 300 years.
