Abstract
We present the first national probabilistic tsunami hazard assessment (PTHA) for Indonesia. This assessment considers tsunami generated from earthquakes near-field sources around Indonesia as well as regional and far-field sources, to define the tsunami hazard at the coastline. The methodology is based on the established monte-carlo approach to probabilistic seismic hazard assessment (PSHA) and has been adapted to tsunami. The earthquake source information is primarily based on the recent Indonesian National Seismic Hazard Map developed by Team-9 and included a consensus-workshop with Indonesia's leading tsunami and earthquake scientists to finalise the input parameters. Results are presented in the form of tsunami hazard maps showing the expected tsunami height at the coast for a given return period (100, 500 and 2500 years) , and also as tsunami probability maps showing the probability of exceeding 0.5m and 3.0m at the coast, which define the thresholds for different tsunami warning levels in the Indonesian Tsunami Early Warning System (Ina-TEWS).
