Overview

  • The 7.3-magnitude quake struck 54 miles south of Sand Point at a depth of about 20 kilometers, according to the U.S. Geological Survey.
  • The National Tsunami Warning Center initially issued a warning, downgraded it to an advisory, and later canceled the alert after observing negligible wave heights.
  • Over a dozen aftershocks followed the mainshock, the largest measuring magnitude 5.2 as of the latest updates.
  • City administrator Debi Schmidt reported no damage or injuries in Sand Point and local authorities say no impacts have been confirmed elsewhere.
  • Alaska’s position on the Pacific Ring of Fire makes magnitude-7-and-above events an annual occurrence, triggering standard tsunami protocols each time.
