Tsunami hazard and risk assessment

This document is the second in a series of hazard-specific risk assessment modules, compiled as part of the Words into Action Guidelines on National Disaster Risk Assessment by UNISDR. This section provides a general introduction on the assessment of tsunami hazard through probabilistic tsunami hazard analysis (PTHA), with alternate models used to better quantify uncertainty. The document also describes exposure and vulnerability assessments and the use of these different risk assessments for long-term disaster risk reduction.
