EARTHQUAKE STATISTICS
Average number of earthquakes
Based on data from the past 54 years and our earthquake archive back to 1900, there are about 8.2 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):
- Mag. 6 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)
- Mag. 5 or higher: 0.04 quakes per year (or 1 quake every 23.8 years)
- Mag. 4 or higher: 1.36 quakes per year
- Mag. 3 or higher: 6.1 quakes per year
- Mag. 2 or higher: 8 quakes per year
The area where this quake occurred has a moderate level of seismic activity. However, It has had at least 3 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.
