Look up quakes! |
California has a high level of seismic activity. Based on data from the past 10 years and our earthquake archive back to 1900, there are about 45,000 quakes on average per year in or near California. 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 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.
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.
The last earthquake in or near California occurred 44 minutes ago and had a magnitude of 0.7:
A light magnitude 0.7 earthquake hit 44 km (27 mi) away from Santa Rosa, California, United States, late in the evening of Monday, Mar 18, 2024 at 11.49 pm local time (America/Los Angeles GMT -7). The quake had a very shallow depth of 1.1 km (0.7 mi) and was too small to be felt by people.
In the past 24 hours, California has had 1 quake of magnitude 3.4 and 5 quakes between 2.0 and 3.0. There were also 113 quakes below magnitude 2.0 which people don't normally feel.
The strongest earthquake in or near California in the past 24 hours had a magnitude of 3.4 and occurred 8 hours ago:
A light magnitude 3.4 earthquake hit 38 km (24 mi) away from Salinas, California, United States, in the afternoon of Monday, Mar 18, 2024 at 4.57 pm local time (America/Los Angeles GMT -7). The quake had a very shallow depth of 9.5 km (5.9 mi) and was not felt (or at least not reported so).
