Landers Earthquake Anniversary: Preparedness Reminder


While many Californians remember the magnitude 6.7 Northridge Earthquake in 1994, the Landers Earthquake two years earlier was actually significantly bigger.

The Landers Earthquake struck on the morning of June 28, 1992. This earthquake hit San Bernardino County with a magnitude 7.3, making it the largest magnitude earthquake in the United States in 40 years.

The power of the earthquake can be seen in the pictures below.

Utilizing lessons learned from those and other earthquakes, California has emerged as one of the country’s leaders in emergency management and disaster preparedness. California’s first-in-the-nation Early Earthquake Warning System provides advanced notification to Californians before shaking starts.

An earthquake can occur anytime and anywhere, so it’s important to know what to do if an earthquake hits your community.


  • Visit Earthquake Warning California to sign up for emergency alerts and to download the MyShake App.
  • Develop an emergency preparedness plan and make sure everyone in your family knows how to drop, cover and hold on until the shaking stops.
  • Pack an emergency supply kit.
