Earthquake statistics

Number of quakes per year

Note:
The apparent increase in the number of quakes is not because global seismic activity has increased, but because the number of seismic networks around the world and their sensitivity to detect smaller quakes has been constantly increasing.
This is most evident if one looks at the number of smaller earthquakes (below magnitude 5). For larger quakes (magnitude 5 or more), the effect disappears after around the 1990s. Since then, the global coverage of earthquake of larger quakes has been nearly complete.

Average number of earthquakes

Based on data from the past 54 years and our earthquake archive back to 1900, there are about 2,100 quakes on average per year near Long Valley volcano:

Mag. 6 or higher: 0.07 quakes per year (or 1 quake every 13.5 years)
Mag. 5 or higher: 0.29 quakes per year (or 1 quake every 3.4 years)
Mag. 4 or higher: 3.6 quakes per year
Mag. 3 or higher: 11.2 quakes per year
Mag. 2 or higher: 103 quakes per year (or 8.6 quakes per month)
Mag. 1 or higher: 692 quakes per year (or 58 quakes per month)

Long Valley caldera (California): felt magnitude 3.8 earthquake

Some felt earthquakes have occurred recently along the southern boundary of Long Valley Caldera, the latest a 3.8 magnitude quakes yesterday. This is not unusual for the volcanic system and does not mean any volcanic eruption should be expected in a near future. The alert status remains green (normal). ... Read all
