Earthquake Warning California
Telecommunications Toolkit & Resources

The California Governor’s Office of Emergency Services (Cal OES) has helped Californians prepare for earthquakes through the Earthquake Warning California campaign. California residents and visitors can find the latest materials, resources, and news relating to the nation’s first statewide, publicly available earthquake warning system at: However, we need your help getting the message out!


For telecommunication providers in California, earthquakes are not a matter of if but when. Telecommunication providers often span a wide region and service thousands of customers that might live along a fault line or in an area that is prone to earthquakes. Telecommunication providers should have a plan in place to help mitigate risk and recover quickly following an earthquake.


Following a disaster like an earthquake, communication may be difficult and is essential in saving lives. By helping share resources with the public, telecommunication providers can play a key role in making Californians more resilient and keeping people safe when the next major earthquake occurs.

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 and download the MyShake App. 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, 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 spread the word about the technology available to 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 users can set up a “HomeBase” location to receive earthquake warnings without having location services turned on.
  • 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.


After an earthquake, individuals may need to reach family members, friends, and emergency services. If the earthquake results in a loss of power, communication channels may be down and additional calls made can tie up the network, making it difficult for someone calling with a life-threatening emergency to receive needed help.


Following a disaster like an earthquake, individuals should:

  • Call 9-1-1 if there is a life-threatening emergency.
  • For non-emergency communication, use text messages, e-mails, or social media instead of making voice calls.


[Insert organization name] encourages our [employees/customers] to have a plan for how to protect themselves in the event of an earthquake, be it onsite, on the road, or at home. If you receive a warning, be sure to react with the assumption that shaking will occur soon after. 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 to help spread the word about the technology available to help keep them safe.
