National Tsunami Hazard Model (NTHM) 2021

This dataset defines the maximum tsunami height (maximum amplitude) expected to be exceeded once every 100, 500, 1000 and 2500 years on average at the 50th and 84th percentile of confidence, as estimated by the model described in Power et al. (2022). The dataset also defines the coastal sections that were used for this modelling. The expected maximum tsunami heights are presented for each of these coastal sections. Please note that the expected maximum tsunami height will typically only occur at one location within each coastal section. It is a conservative (pessimistic) assumption if this height is used throughout the section. DOI: https://doi.org/10.21420/C3CK-FB93 Cite data as: GNS Science. (2022).
