Earthquake statistics

Average number of earthquakes

Based on data from the past 14 years and our earthquake archive back to 1900, there are about 22,000 quakes on average per year in Alaska and the Aleutian Islands:
  • Mag. 8 or higher: 0.1 quakes per year (or 1 quake every 10.3 years)
  • Mag. 7 or higher: 0.82 quakes per year (or 1 quake every 1.2 years)
  • Mag. 6 or higher: 5.7 quakes per year
  • Mag. 5 or higher: 40 quakes per year (or 3.3 quakes per month)
  • Mag. 4 or higher: 201 quakes per year (or 16.7 quakes per month)
  • Mag. 3 or higher: 1,000 quakes per year (or 2.9 quakes per day)
  • Mag. 2 or higher: 5,400 quakes per year (or 14.9 quakes per day)
  • Mag. 1 or higher: 19,000 quakes per year (or 53 quakes per day)
Alaska has a very high level of seismic activity. Alaska has had at least 13 quakes above magnitude 8 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.
