Most residents in the area of the strongest shaking (red area) did not receive any warning, and 41 people were killed. Nevertheless, slowing trains may be possible and potentially beneficial.

The National Earthquake Hazards Reduction Program (NEHRP) leads the federal government’s efforts to reduce the fatalities, injuries and property losses caused by earthquakes. A crucial piece of information that could be better communicated is that EEW alerts typically have a blind zone, an area around the earthquake epicenter that cannot be alerted before the strong shaking starts.

Earthquake early warning (EEW) entails detection of initial earthquake shaking and rapid estimation and notification to users prior to imminent, stronger shaking. With all three latencies, only the very lightest shaken areas would have received a warning.
