Alaska Airlines requested a nationwide ground stop for all its mainline aircraft on Sunday, according to the Federal Aviation Administration’s (FAA) status page. The FAA’s website showed that the order affected all destinations served by Alaska Airlines’ mainline fleet.

Alaska Airlines grounded all of its planes on Sunday night due to what the airline called an IT outage.

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.
