Better earthquake alert system arrives May 4 for Washington state

The ShakeAlert® Earthquake Early Warning system will go live on mobile phones in Washington state on Tuesday, May 4, completing the West Coast rollout of the new technology.
The system is capable of giving residents critical seconds of warning before earthquake shaking arrives — sooner than current public technology allowed.
On or before May 4, residents will want to check their phones to ensure that Wireless Emergency Alerts are turned on. Most carriers have this setting turned on automatically, but some people have chosen to disable them. Learn how at https://mil.wa.gov/alerts
When the system goes live, Google has notified our agency that users of Android phones will have the potential to get notifications through both Wireless Emergency Alerts and their phones’ own built-in software (which doesn’t require a specific app).
As the campaign implores: May the Fourth Be With You!
