How to Get Warnings in Advance of an Earthquake
Types of Alerts
The Earthquake Warning for California systems use science, state-of-the-art ground motion monitoring, as well as new and existing alerting methods to deliver warnings to people via cell phones before the strongest shaking arrives. Seconds to tens of seconds of alert can provide opportunity to take life-saving actions such as Drop, Cover, and Hold On and put devices into various forms of a safe mode. The speed of the alert will vary depending on one's distance from the origin of the earthquake. The closer one is to origin, the quicker one will receive the alert. In some cases people may receive an alert once they feel shaking or after an earthquake passes.
For the first time, you can receive warning of an earthquake before you feel shaking. Earthquake Warning California can give you seconds of notice using the following tools:
- MyShake App
- Android Earthquake Alerts
- Wireless Emergency Alerts (WEAs).
When you receive an alert or feel shaking drop, cover and hold on!
