Tsunami Preparedness and Safety Information
What is a Tsunami?
A tsunami (soo-NAH-mee) is a series of traveling ocean waves of extremely long length. These generally appear as a large, steep wave face and produce rapid flooding of low-lying coastal areas. These are generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. This can also be generated by landslides, both above and beneath the surface of the ocean.
Warnings
It may take hours for tsunami waves to reach the Coast of Maui County following an earthquake far out in the Pacific Ocean. The Pacific Tsunami Warning Center located on Oahu alerts local officials who may order evacuation. Some isolated areas may not receive official announcements. If you notice a sudden drop or rise in sea level, it may be a warning of impending danger. Move to high ground or inland immediately. Review the Warning Procedures and Information web page for more information about Maui County's warning system.

- Be prepared to survive on your own for a minimum of three days.
