Earthquake Warning California
General Public Toolkit & Resources

The California Governor’s Office of Emergency Services (Cal OES) launched the “Don’t Get Caught Off Guard” campaign in October 2020 to help inform communities throughout California about the Earthquake Warning California system. California residents can find the latest materials, resources, and news relating to the nation’s first statewide, publicly available earthquake warning system on the newly revamped website: earthquake.ca.gov.

For Californians, earthquakes are not a matter of if, but when. Whether individuals reside, go to school, or work in an area that is prone to earthquakes, it is essential to have an emergency plan in place to help reduce risks of injuries and recover quickly following an earthquake. By helping share information with neighbors, family members, friends, and others within the community, individuals can play a key role in helping others appropriately prepare for the next major earthquake. Helping others understand the importance of being earthquake prepared can reduce the number of injuries and deaths during an earthquake and lead to a quick recovery for a resilient California.

April is Earthquake Preparedness Month in California! We know that there are many things to be worried about, but when it comes to earthquakes, it is not a matter of if one will occur, but when. The California Governor’s Office of Emergency Services (Cal OES) is encouraging residents to take the time to update their emergency plan, download the MyShake App, and adjust their phone settings. Many things in life may catch us off guard; but now, earthquakes don’t have to!

GAME CHANGER: Californians can now get warnings for earthquakes from Earthquake Warning California. By downloading the FREE MyShake App and adjusting phone settings, people can get a jump start, in some cases before shaking can be felt to take protective actions to DROP, COVER, and HOLD ON (or LOCK, COVER, and HOLD ON if using a wheelchair).

If you receive a warning or feel shaking, there are moments to act. There may be circumstances where a warning is issued, but no shaking occurs. It is always better to be on the side of caution when it comes to earthquakes. We encourage you to share this information with friends and family in California to help spread the word about the technology available to help keep them safe.

Here are some of the ways to receive earthquake warnings:

• MyShake App. An app that can be downloaded for mobile devices at no-cost from Google Play and the Apple App Store. App location services must be set to “always-on” so that ground sensors can alert those in the nearby area when shaking is detected.
• Android Earthquake Alerts. Included in new or updated Android devices, the system uses the same technology as the MyShake App.
• Wireless Emergency Alerts (WEAs). Text-like messages from the government during emergency situations. This includes: Presidential, Imminent Threats (fire, earthquake, floods, etc.), and AMBER alerts.

When an earthquake warning is issued from any of these sources, individuals should quickly take protective actions to stay safe, such as dropping to the ground, covering their head with their arms, and holding onto their neck with both hands until shaking stops. Do not stand in doorways or near glass windows.
