  4. U.S.National Tsunami Hazard Mitigation Program Reduce the Impact of Tsunamis on U.S. Coastal Communities State Agencies Alaska California Hawaii Oregon Washington Federal Agencies • National Oceanic and Atmospheric Admin. • U.S. Geological Survey • Federal Emergency Management Agency Frank González, NOAA TIME Center, PMEL, Seattle, WA

  5. Recent Accomplishment • • 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 2. Model Database 1. Real-time Tsunami & Seismic Data 3. Site-specific Forecasts • • 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

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

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

  10. •Hilo Tide Gage 1. Pre-computed Nested Grid Database of Offshore Values 2. Provides Initial Conditions for Real-time Inundation Simulation (~10 Minutes)

  11. Result: “Blind” Forecast at Hilo
