In a statement to CBS News, the carrier said that, "At approximately 8 p.m. Pacific on Sunday, Alaska Airlines experienced an IT outage that's impacting our operations. We requested a temporary, system-wide ground stop for Alaska and Horizon Air flights until the issue is resolved.

The USGS described the earthquake as "notable," confirming that it may have been felt by residents in Sand Point and nearby areas. No tsunami warning was issued. Local emergency officials are monitoring the situation but have not reported any injuries or damage so far.

Ground shaking was strongest in Sand Point, with reports of "objects flying out of the pantry and off of shelves," noted the Alaska Earthquake Center.

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.
