Abstract
New Zealand is vulnerable to tsunami from many sources, and some parts of the coast are more vulnerable than others. The New Zealand National Tsunami Hazard Model (NTHM) provides a nationwide calculation of the level of tsunami hazard, permitting evaluation and comparison of tsunami hazard for the whole coast of New Zealand. The NTHM was originally released in 2013 and subsequently revised in 2021. This report presents results from the 2021 NTHM. This report contains tsunami hazard curves and deaggregation pie charts for 268 sections of the New Zealand coast, each of which is approximately 20 km long. The results are calculated using the methodology described in the report The 2021 update to New Zealand’s National Tsunami Hazard Model (Power et al. 2022). (The authors)
