Earthquake Early Warning (EEW) systems use earthquake science and monitoring technology to alert people when shaking waves generated by an earthquake are expected to arrive at their location. The seconds to minutes of advance warning can allow people to take actions to protect life and property. Research shows, however, the alerts generated by EEW can be improved by incorporating data from the Global Navigation Satellite System (GNSS).
