SUMMARY REPORT OF 2nd
The 2nd meeting of the SWPIO TWS Working Group was convened from to ,
Dr. Phil Cummins,
Dr. Laura Kong,
Dr. Stuart Weinstein, PTWC
The following Terms of Reference were discussed and actions reported on:
A presentation entitled “Feasibility Study for a Tsunami Warning System in the SW Pacific”
was given in the “Tsunami Training: Warning Guidance” session by Phil R. Cummins of Geoscience
A tsunami warning system for the SW Pacific would likely involve establishment of a regional center capable of acquiring and rapidly analysing both seismic and sea level data. This would require a reliable high-bandwidth internet connection as well as highly-trained staff, and would likely take several years to develop. However, a proposal was put forward for a simple feasibility study that would, for a limited time, use earthquake alerts already produced by international agencies. A regional office would monitor only the sea level data from the SPSLCMP tide gauge network to verify whether a tsunami has actually occurred. This would have the advantage that the process of monitoring earthquake alerts and sea level data could be initiated at relatively modest cost, and potential for reliable and timely tsunami warnings could be assessed. If the results of the study were positive, suggesting that reliable warnings could be issued quickly, this may provide support for the establishment of a permanent tsunami warning system.
5. The proposal generated much interest and was followed on Day 3 of the SPTAW by a discussion session which recommended the formation of a South Pacific Working Group and endorsed the proposal to investigate the feasibility for tsunami warning services. These recommendations were further elaborated upon to formulate SPTAW Recommendations (Objectives, Outcomes, Activities) by the Tsunami Hazard & Risk Identification Working Group in the session that followed. The Workshop Recommendations are being presented for further discussion at the SOPAC
The Tsunami Session currently consists of at least about 8-9 papers, including the following:
Summary of SPTAW (SOPAC,
Historical Database (GTDB/ITDB, Gaye Downes & Hugh Cowans)
SWPIO TWS Feasibility Study/SPTAW Feasibility Study (Cummins & Kaluwin)
PTWC (Chip McCreery)

Recommendation ITSU-XIX.4: Working Group on the Tsunami Warning System in the Southwest Pacific and Indian Ocean [endoresed by the IOC Executive Council at its 37th Session in June 2004]
WORKING GROUP ON THE TSUNAMI WARNING SYSTEM IN THE SOUTHWEST PACIFIC AND INDIAN OCEAN
The International Co-ordination Group for the Tsunami Warning System in the Pacific,
Recognizing that the Southwest Pacific and Indian Ocean has a significant threat from both local and distant tsunamis;
Further recognizing that some areas of this region are not covered by the PTWC;
Noting the interest of Member States in the Indian Ocean and Southwest Pacific regions to enhance their tsunami warning services;
Acknowledges that Indonesia has decided to develop its National Tsunami Warning System with already existing and planned upgrades to seismic and sea-level networks and that the PTWC provides distant tsunami warnings for the Southwest Pacific;
Further acknowledging that there may be mutual benefits to these regions and to the Tsunami Warning System in the Pacific from the establishment of this system;
Decides to establish an intersessional Working Group on the Southwest Pacific and Indian Ocean with the following Terms of Reference:
- to evaluate capabilities of countries in these regions for providing tsunami warning services;
- to ascertain requirements from countries in the Southwest Pacific and Indian Ocean for the tsunami warning services.
Requests Australia and ITIC to prepare a draft prior to the next SOPAC meeting for consideration by the Working Group.
Recommends that the Group be composed of representatives from Indonesia, Australia, Fiji, New Zealand, Japan, Observer from Papua New Guinea and the Directors of ITIC and PTWC and Chaired by the Representative of Indonesia.
Acknowledges that ITSU is the Co-ordination Body for the Tsunami Warning System in the Pacific (TWSP) and encourages non-ITSU Member States to contact the IOC Secretariat to request membership of the ICG/ITSU.
