Probabilistic Tsunami Hazard Assessment (PTHA) and tsunami inundation modeling have been identified by the five partner countries of the North-West Indian Ocean (NWIO) region (India, Iran and Pakistan with funding from the project; Oman and United Arab Emirates (UAE) through self-funding), as priority topics to be addressed in in order to improve community awareness, risk assessment, inundation mapping, and evacuation planning in support of tsunami preparedness.

The UNESCAP TTF-31 project is supporting the finalisation of a Probabilistic Tsunami Hazard Assessment (PTHA (V1.0)), including training of NWIO experts in its architecture and use. This includes a scientific exchange workshop to share the PTHA results with the region for adoption, as well as report on the latest regional/international studies on the tsunami hazard in the Makran Subduction Zone (MSZ). The project has also supported the establishment of a NWIO Regional Working Group on Tsunami Inundation Modelling and Mapping (NWIO RWG-TIMM) with membership from the five countries participating in the project and with input from international experts, to foster ongoing regional cooperation and exchange of knowledge on inundation modelling and mapping. The project will provide information on existing approaches, methodologies and input data for tsunami inundation modelling and mapping. The NWIO RWG-TIMM will develop a unified approach for tsunami inundation modeling in order to assure inter-comparable results throughout the region.

By this the participating countries can develop a solid foundation that will help achieving the goals of the UN Ocean Decade Tsunami Programme to make all communities highly at risk prepared for and resilient to tsunamis by 2030.

Through this scientific exchange workshop, it is intended to distribute, report, and discuss the recent results of an extensive PTHA for the NWIO and to discuss the utilisation of the outcomes for tsunami inundation modelling and mapping for evacuation planning and risk assessment in the region. The workshop has the following objectives:

• Provide background information on the TTF-31 project and related initiatives, such as the UN Ocean Decade Tsunami Programme.
• Report the outcomes and results of the Probabilistic Tsunami Hazard Assessment (PTHA) for the North-West Indian Ocean (NWIO) region under guidance of GFZ and INGV.
• Discuss future development and possible extension of the PTHA to include complex tsunami sources in the NWIO region.
• Examine potential uses of the results of the PTHA in developing community awareness and risk management.
• Discuss the utilisation of the PTHA for inundation modeling and mapping in the NWIO.
• Explore further activities to be undertaken under the framework of the project, including next steps towards a joint strategy for implementing tsunami inundation modelling in the region and nationally.
• Discuss and plan possible future realisations of inundation mapping in the region in the project Pilot Areas, as part of possible future phases of the project.
