Abstract
Recent occurrences of catastrophic events of coupled ground motions and tsunami waves have raised concerns about the need for comprehensive tsunami mitigation planning. In this field, the quantification of tsunami waves, which can be obtained from tsunami hazard assessment, is an important data. The results of tsunami hazard assessments show the intensity of the impact on a coastal area versus its return period. This study performs probabilistic tsunami hazard assessment (PTHA) in Lhoknga coastline, Aceh, Indonesia. PTHA employs information about earthquake-caused tsunami faults and their return period. The generation, propagation, and inundation of tsunami waves on the coastline are simulated using available tsunami numerical simulation. In addition, smoothed particle hydrodynamic (SPH) method is used to observe the spread of tsunami flood on the dry land. This open new opportunity to assess tsunami flooding hazard within a probabilistic environment.
