Earthquake early warning (EEW) systems are primarily based on two concepts that enable alerts to be sent ahead of the occurrence of earthquake-induced ground shaking at target locations (on the order of seconds to minutes): (1) Information travels faster than seismic (i.e., mechanical) waves; and (2) most of the energy of an earthquake is carried by the S- and
