Abstract

This study is motivated by the tsunami event caused by Mount Anak Krakatau flank collapse on 22nd December 2018 which affected vital areas in Southern Sumatera and Western Java. A tsunami simulation will be carried out by using a 2D Non-Linear Shallow Water Equation Model to estimate the volume of the initial source as well as their tsunami mode at shores. Various scenarios of initial water volume replicating the tsunami source were applied, where the tsunami heights and their periods reach shores are validated with mareogram data at four Stations. The fact that the remaining materials of Mount Anak Krakatau after the 2018 event are still potential to generate a hazardous tsunami in the future and threaten the coastal infrastructures along the coastal Sunda Strait area. In this study, the validated parameters resulting from the 2018 event above are applied to model of the plausible worst scenario where the entire of the flank of Mount Anak Krakatau potentially collapses in the future. The study is important to estimate the tsunami hazard potential in the future that obviously influencing major activities and life's in vital industrial-urban area in Southern Sumatera and Western Java.
