Geoscience Australia(GA) and the Pacific Community (SPC) partnered towards the development of a peer-reviewed guideline to assess tsunami inundation hazards in the Pacific Island region. The guideline leverages and optimizes the use of GA's 2018 Probabilistic Tsunami Hazard  Assessment (PTHA18) and aims to provide member countries, technical partners, and consultants with methodologies and tools to support hight quality standard for earthquake-generated tsunami hazard assessment across the region.

This guideline is set as a living document which should be revisited to account for future advancement in global and regional tsunami hazard and risk science.
