BART has installed and continues to enhance a network of seismic sensors (an [[earthquake warning system]]) to trigger a system halt in the event of a major event, this to include automated event progression analysis to determine the best action with regard to individual trains for maximum safety (a fault rip can take up to several tens of seconds to completely propagate from the epicenter to the affected locations). Such sensor networks and warning devices have a potential to reduce the haz
zards from falling objects and furnishings provided that the people notified are well trained in appropriate responses (similar to the [[Cold War|Cold War's]] "[[duck and cover]]" training of schoolchildren).
