Introduction
摘要
Probabilistic tsunami hazard and risk assessment methods have evolved quickly over the past 10 to 15 years. While earthquake risk, which has been treated by probabilistic methods since the 1960s, can be represented by a single workflow, tsunami risk is characterized by several different and cascading workflows, and it is much more dependent on numerical simulations. Given the rapidly evolving research landscape, there is a need to establish best practices for probabilistic tsunami hazard and risk assessment (abbreviated PTHA and PTRA, respectively) to improve reliability, comparability and reproducibility of studies applying such methods. More than 50 tsunami scientists have joined forces to develop this so-called cookbook providing recommendations and workflows for both PTHA and PTRA.
