Magnitude 6.1 earthquake southwest of Sand Point, Alaska

At 11:59 AM Alaskan Daylight Time on July 16, an earthquake with preliminary magnitude 6.1 occurred 50 miles/80 Km southwest of Sand Point, Alaska .

The magnitude is such that a tsunami IS NOT EXPECTED. However, in coastal areas of intense shaking, locally generated tsunamis can be triggered by underwater landslides. This will be the only WCATWC message issued for this event.

The location and magnitude are based on preliminary information. Further information will be issued by the United States Geological Survey or the appropriate regional seismic network.
