Abstract
The source of the earthquake and tsunami in the Indian Ocean, particularly in South Java, is needed for mitigation purposes that are beneficial to life on the expanding south coast of Java. Cilacap City is one of the important cities in driving development in south coast of Java. This study aims to perform a tsunami simulation with the study area of Cilacap City. The simulations are carried out with software which is based on the shallow water equations. The epicenter varies in the form of coordinate points in the megathrust segment of west-central Java. The simulation results show that Cilacap City is prone to tsunami disasters because the tsunami amplitude on the coast can reach 10.7 m and the arrival time of the tsunami is between 10 and 20 min. These results may complement previous data assessing the potential for tsunamis along the Sumatran Java Ring of Fire.
