Summary

Make the nation's tsunami warning and response systems better so people and property are safer. That includes upgrading the warning network to be more accurate, cover all threats, and cut false alarms; improving maps, models, and research; and setting common rules for alerts, education, and outreach so warned people and those at risk know what to do and can spot local warning signs. Help other countries set up regional warning systems, build community resilience to tsunamis and similar coastal hazards, and improve coordination among Federal, State, and international partners.
