How earthquake early warning works
Earthquake early warning detects an earthquake that has already begun and may warn some places before strong shaking arrives. It is different from predicting when and where a future earthquake will start.
Useful time can be very short
Detection, analysis and message delivery take time. Places close to the source may receive no advance warning. Early estimates of location, magnitude and expected shaking can be revised or wrong, particularly when several events overlap. Use the official warning service available for your location.
What QuakeMap Live provides
QuakeMap Live displays reported catalogue events and their source update times. It is not an official alert channel and does not deliver earthquake early warnings. A catalogue’s tsunami-related indicator is also not a current tsunami warning. Follow your authorities’ warning and evacuation channels directly.
