A tsunami mitigation plan needs to:
- Quickly confirm potentially destructive tsunamis and reduce false alarms.
- Address local tsunami mitigation and the needs of coastal residents.
- Improve coordination and exchange of information to better utilize existing resources.
- Sustain support at state and local level for long-term tsunami hazard.
- Improve the awareness and preparedness of communities for tsunamis:
- Raise the awareness of affected populations.
- Supply tsunami evacuation maps.
- Improve tsunami warning systems.
- Incorporate tsunami planning into state and federal all-hazards mitigation programmes.
