Enhancing Tsunami Early Warning Systems in the Indian Ocean Region

This project aims to improve tsunami early warning systems by addressing gaps in seismic networks, sea-level gauges, and real-time data processing. It also focuses on building public awareness and preparedness, training emergency management agencies, and deploying scientists in the Indian Ocean Region.

Presentation Transcript

  1. Group 1 Warning and preparedness

  2. Current Knowledge & Capacity • Rapid earthquake solution okay • Earthquake rupture mechanism capacity poor • Deep ocean tsunami modeling okay • Tide gauge network in IO poor • Run-up modeling poor • Have good expertise to build up the poor systems if resources available.

  3. Current Knowledge & Capacity • Warning systems for non-sudden impact disasters (cyclone, hail, etc) are good. • Public preparedness for cyclones are good. • Have expertise to build on these existing systems and apply them to Tsunami Early Warning System (TEWS) • Have expertise in community awareness and education programs.

  4. Gaps in Knowledge & Capacity • Seismic networks currently inadequate for a TEWS • Sea-level gauges very inadequate • Real-time processing of seismic and sea level data inadequate • No agreed false warning rate

  5. Gaps in Knowledge & Capacity • Systems for rapid dissemination of warnings are inadequate • Public awareness of earthquake and tsunami risk in Australia very low • Preparedness of emergency authorities to catastrophic sudden impact disasters unclear

  6. Contribution to Region • Lead in building systems for exchange of seismic and sea-level data • Install seismic and sea-level stations on our territory. Install seismic and sea-level stations in IO countries. • Has expertise to operate IOTEWS • Has expertise in undertaking historical and paleo tsunami studies in IO • Build framework for deploying scientists to effected regions

  7. Contribution to Region • Assist IO countries in developing appropriate education material • Assist IO countries in developing education programs • Provide training to emergency management agencies to build capacity • Provide scientists to the region
