Earthquakes in California & California's Earthquake History

​​Earthquakes happen all the time

  • California is home to two-thirds of our nation's earthquake risk.
  • In the next 30 years, according to the most recent Uniform California Earthquake Rupture Forecast (UCERF), there is a greater than 99% chance that a magnitude 6.7 or greater earthquake capable of causing extensive damage and loss of life will occur in California.
  • California has thousands of known faults crisscrossing the state, and more than 500 are considered active. But some of the world's most devastating earthquakes, such as the Northridge quake, have occurred on previously unknown faults.
  • As the magnitude 6.9 Loma Prieta earthquake of 1989 proved, sometimes the most extensive earthquake damage can occur many miles from the fault and epicenter. The USGS reports that the most severe property damage occurred in Oakland and San Francisco—more than 60 miles from the epicenter in the Santa Cruz Mountains.

California's Earthquake History

The earliest recorded quake occurred in 1769 in the Los Angeles region during a land expedition led by Gaspar de Portolá. According to the diaries of the members of the expedition, the strong quake occurred on July 28, followed by several smaller quakes. Scientists believe this was a major earthquake, similar in size to the de​vastating 1933 Long Beach quake.
