Emergency Preparedness: ShakeAlert

    As of March 11, 2021, the US Geologic Survey ShakeAlert early warning system is available in Oregon. It does not predict earthquakes but detects them quickly and sends a real-time alert to mobile phones to give you a brief warning of an earthquake in your location.

    Use those few seconds of warning to take action: 

    • Drop where you are onto your hands and knees 
    • Cover your head and neck for protection like under a sturdy table 
    • Hold on until shaking stops 

    ShakeAlert alerts are sent through the Wireless Emergency Alert infrastructure using your phone’s location information when connected to a wireless tower.

    You won’t get a ShakeAlert message unless your current location is expected to feel an intensity of weak or light shaking (or greater) for earthquakes of a magnitude 4.5 or greater. This intensity of earthquake means that it would be felt by multiple people who may notice a rattling or vibration – something like the passing of a large truck. You might also see hanging objects in your home swing.

    There is no sign up process to receive ShakeAlert alerts, similar to Amber alerts.

    More information about ShakeAlert, and how to verify that your phone will receive those alerts, is available online at ORShakeAlert.US.
