Earthquake statistics

Average number of earthquakes

Based on data from the past 10 years and our earthquake archive back to 1900, there are about 8,600 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):
  • Mag. 7 or higher: 0.04 quakes per year (or 1 quake every 25 years)
  • Mag. 6 or higher: 0.24 quakes per year (or 1 quake every 4.2 years)
  • Mag. 5 or higher: 3.2 quakes per year
  • Mag. 4 or higher: 17.2 quakes per year
  • Mag. 3 or higher: 108 quakes per year (or 9 quakes per month)
  • Mag. 2 or higher: 577 quakes per year (or 48 quakes per month)
  • Mag. 1 or higher: 843 quakes per year (or 70 quakes per month)
The area where this quake occurred has a very high level of seismic activity. It has had at least 5 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.
