Earthquake Warning California offers early warning earthquake app

April is National Earthquake Preparedness Month, and Earthquake Warning California is the first in the nation early warning system for earthquakes and includes technology such as the free MyShake App and Android Earthquake Alerts that can give mobile users a few moments notice before shaking so that they can take protective actions such as to drop, cover, and hold on.

Amanda Moyer, who is the Program Manager of Earthquake Warning California for the California Governor's Office of Emergency Services, discusses how these warning systems work.
