Abstract

Bali Island is an area that is flanked by two zones of earthquake potential to cause a tsunami. In this study produced the estimated tsunami heights (run up) and the tsunami arrival times (ETA) by simulating a tsunami with some magnitude variety of the earthquake using software called TOAST. The estimation is obtained by making a scenario of earthquake from parameters of earthquakes that have occurred and raised tsunami on the Bali Island as a reference. The observation area is in some coastal areas of Bali Island. The maximum value of run up is between 21.16 m to 55.6 m with tsunami arrival time is between 120 minutes to less than 15 minutes after an earthquake with 9.6 SR of magnitude. The area around Kuta Beach Badung is an area with high potential for run up.
