Earthquake!Tsunami? |
| Time = 0 |
|
 |
Destructive tsunamis originate primarily in subduction zones around the Pacific Rim. |
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.
