5. Recent Accomplishment 26 Dec 2004 Indian Ocean Tsunami 26 Dec 2004 Indian Ocean Tsunami Demonstrated & interpreted global distribution patterns Model Simulations and Tide Gage time series Primary physics: Seismic line-source characteristics; World coastline reflections; Mid-ocean ridge wave guides

6. 26 Dec 04 Tsunami Simulation (Vasily Titov, Diego Arcas)

7. Recent Accomplishment Developed Tsunami Forecasting System Methodology Developed Tsunami Forecasting System Methodology -Integrates real-time Measurement & Modeling technologies -Will improve speed and reliability of Tsunami Warnings -Prototype tested and available -Valuable research tool -Operational version under development 1. Real-time Tsunami & Seismic Data 2. Model Database 3. Site-specific Forecasts

8. Example of Tsunami Forecast: 17 Nov 2003 M w =7.5 3cm -3 3cm -3 Q: How would you interpret these data ?

9. 3cm -3 3cm -3 Example of Tsunami Forecast: 17 Nov 2003 A: Operational Forecast Model Q: How would you interpret these data ?
