1 Dr. Laura S. L. Kong, Director International Tsunami Information Centre HISTORY Regional TWS 1997: ITSU XVI noted need for due to high seismic hazard, destructive tsunami history 1989: TWSP Master Plan (1 st ed) 1987: ITSU X recommendation 1985: ITSU X noted 2003: Krakatau 120-year Memorial ws recommends est Indonesia TWS 1992 With later expansion Indonesia TWC could serve as regional TWC; support volunteered by Australia

5 2 TSUNAMI THREATS LOCAL / REGIONAL TSUNAMI: Generated nearby Strikes shore quickly (w/i minutes) => NO TIME for official evacuation Highest Runups Damage only to limited area Arop, PNG, 1998 DISTANT / PACIFIC-WIDE TSUNAMI: Generated far away (Pacific Rim) Strikes shore later (5+ hours, 14 hrs Chile to Tonga) => TIME for official evacuation Widespread Damage SPTAW Workshop GOALS: Raise Awareness, Education ID National, Regional Priorities & Actions PARTICIPANTS: American Samoa, Cook Islands, Fiji Islands, Papua New Guinea, Samoa, Solomon Islands, Tonga, and Vanuatu RESOURCE SPEAKERS: ITIC, PTWC, Japan, Russia USA, New Zealand, Australia, Indonesia, Pacific Disaster Center ORGANIZERS/SPONSORS: SOPAC, UNESCO/IOC ICG/ITSU 5

6 SPTAW Strategic Recommendations for Addressing Tsunami Risks EMERGING THEMES - MEASURES OF SUCCESS: Involve all countries and national stakeholders to build capacity and develop human resources to support the data information needs in tsunami risk reduction. Establish partnerships to integrate regional risk management tasks within the CHARM framework. Build international and intra-regional cooperative relationships to support tsunami risk reduction activities (modeling, risk assessments, best management practices, data sharing, warning systems etc.). Advocate to ensure Information Technology and Communication (ITC) infrastructure sufficiently supports regional and national requirements for tsunami warning services SPTAW User Survey: : Emerging Statements National Tsunami Contacts: Countries have designated contact points Tsunamis recognized as national threat want mitigation Not all manned 24hr-7days Intl Tsu Warnings received through various media Need back-up Warning Systems: Regional & Local Warnings No or inadequate EWS exists Need to support strengthen monitoring Intl Tsu Warnings communicated to the public Varying levels of timeliness and effectiveness Locally generated tsunamis Most countries guided by general emergency procedures, only PNG has Local Warning System 6

7 SPTAW User Survey: Emerging Statements Hazard, Risks & Modelling: High Risk In All Countries Need to map levels of vulnerability Modeling concept embraced in all countries Need more work to improve topo and bathymetry maps Tsunami Preparedness: Varying levels of Public education awareness programmes through NDMO Need to update material Need to evaluate School training thru established curriculum Need to update SPTAW Workshop Priority Actions PRIORITY ACTIONS: SOPAC Tsunami Working Group Regional Tsunami Warning Alerts National Tsunami Response Plans 7
