Destructive tsunamis originate primarily in subduction zones around the Pacific Rim. |
![](/peth04/20041113081945im_/http://www.pmel.noaa.gov/tsunami/Oceans99/Images/_box.gif) Not every earthquake generates a tsunami. |
Model simulations combined with real-time tsunami measurements will help assess the hazard. |

Tsunami Forecast Guidance |
Time = 1 hour |
Hawaii Civil Defense must decide whether to call a tsunami evacuation within an hour of a Pacific earthquake.
The integrated DART/model database system will provide more rapid and accurate guidance to emergency managers.
Schedule:
An operational network of six DART stations will be deployed over the next two years.
The data-assimilation scheme and database for Hawaii are presently under development, to be completed by 2003.
