Tsunamis can be deadly, but they needn’t be. Early warning and early action are effective tools to protect people, saving lives, and preventing the hazard from becoming a disaster. To be effective, tsunami early-warning systems must cover every at-risk person, they must be multi-hazard, and communities must be prepared so they can act quickly.
