This document contains general guidance for actions which need to be considered when a Tsunami Warning is issued. It is not intended as a definitive response document but may be used as the basis for the development of detailed business plans.

NOTE 1:

If an Urgent Tsunami Warning is issued without the shaking associated with a local earthquake or tremor, immediately leave or vertically evacuate all tsunami evacuation zones.

NOTE 2:

If a local earthquake or tremor makes it difficult to stand or maintain balance:

If indoors, take cover under a desk, table, or supported doorway.

If outdoors, stay in open areas until the shaking stops.

Then, as conditions permit, immediately leave or vertically evacuate all tsunami evacuation zones.

  Civil Defense sirens will sound when a Tsunami Warning is issued. See the General Information section for a time table of additional siren activations.
