Earthquake statistics

Number of quakes per year

Note:
The apparent increase in the number of quakes since around 2010 is not because seismic activity has increased, but mostly due to three factors:
1) We only started to systematically collect seismic data for smaller quakes worldwide since 2010.
2) The number of seismic networks around the world and their sensitivity to detect smaller quakes has increased drastically in recent years.
3) Data availability through the internet has increased significantly as well. Many national agencies only started reporting earthquakes publicly in the past 10 years or so.

Average number of earthquakes

Based on data from the past 10 years and our earthquake archive back to 1900, there are about 410,000 quakes on average per year in or near California:
  • Mag. 7 or higher: 0.15 quakes per year (or 1 quake every 6.7 years)
  • Mag. 6 or higher: 1.04 quakes per year
  • Mag. 5 or higher: 6.3 quakes per year
  • Mag. 4 or higher: 53 quakes per year
  • Mag. 3 or higher: 557 quakes per year (or 46 quakes per month)
  • Mag. 2 or higher: 4,400 quakes per year (or 12.2 quakes per day)
  • Mag. 1 or higher: 23,000 quakes per year (or 62 quakes per day)
California has a moderate level of seismic activity. However, California has had at least 19 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.

California Earthquake FAQ

How frequent are earthquakes in or near California?

California has a moderate level of seismic activity. Based on data from the past 10 years and our earthquake archive back to 1900, there are about 410,000 quakes on average per year in or near California. However, California has had at least 19 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.

How many quakes occur in California every day?

California has about 10-15 quakes every day. Most of them are too small to be felt by humans, although there is usually one or two that are.
Typically there are 1-2 quakes of magnitudes greater than 3 every day. Quakes of magnitude 4+ occur about once every 5 days on average.
Magnitude 5+ events are about once every 2 months, and strong quakes from magnitude 6+ occur on average once every 4-5 months.

Why does California have so many quakes?

California is located near the boundary between the Pacific and North American tectonic plates. In the area of California, it is called a transform boundary, because the movement of the two plates is mostly a side-wise sliding alongside each other. The Pacific Plate is moving northwest relative to the North American plate, at a rate of approx. 33-37 millimeters (1.3-1.5 in) per year on average.
This creates a complex system of very active fault systems, the most prominent being the San Andreas Fault, which runs for roughly 750 mi (1,200 km) through California. However, there are also many other faults including some found directly underneath the State's major cities including L.A. and San Francisco.

When was the latest earthquake in or near California?

The last earthquake in or near California occurred 21 minutes ago:

A light magnitude 1.8 earthquake hit 28 km (17 mi) away from California City, California,  United States, around noon of Thursday, Feb 29, 2024 at 1.57 pm local time (America/Los Angeles GMT -8). The quake had a very shallow depth of 7.3 km (4.5 mi) and was too small to be felt by people.

How many quakes were there in or near California in the past 24 hours?

In the past 24 hours, California has had 0 quakes of magnitude 4.0 or above, 1 quake of magnitude 3.5, and 8 quakes between 2.0 and 3.0. There were also 77 quakes below magnitude 2.0 which people don't normally feel.

What was the strongest quake in or near California in the past 24 hours?

The strongest earthquake in or near California in the past 24 hours occurred 12 hours ago:

A strong magnitude 4.9 earthquake occurred under the sea near the coast of  United States in the early morning of Thursday, Feb 29, 2024 at 2.28 am local time (GMT -8). The quake had a very shallow depth of 10 km (6 mi) and was not felt (or at least not reported so).
