ICG/PTWS Working Group 1

Terms of Reference of ICG/PTWS Working Group 1: Understanding Tsunami Risk (as of ICG/PTWS-XXX)

1. Develop and promote best practice tsunami risk assessment material, programmes, standards, and tools for understanding tsunami risk, to support emergency management and early warning, including but not limited to:
   • hazard assessment and coastal inundation models and products
   • risk assessment methodology and risk forecasting
   • scenario assessments including maximum credible and most likely events to understand likely exposure, vulnerability, and event frequency
   • forecast and threat models
   • evacuation and inundation modelling
   • use of new and improved data including digital elevation modelling (DEM), GNSS and paleotsunami information

2. Work with scientific experts to support Member State tsunami risk assessment.

3. Improve best practice for assessing risk of local source and non-seismic tsunami sources.

4. Develop projects to address gaps or areas for improvement in tsunami risk assessment, this may include land-use planning, vertical evacuation or supporting early warning improvements.

The Group will be composed of members nominated by Member States, with two co-chairs, one from a science and one from a disaster risk management background, to be elected.
