Description
The history of earthquakes in the southern region of Java Island has seen large earthquakes with Mw above 7.0, including earthquake and tsunami events in 1921 (Mw 7.6), 1994 (Mw 7.6), 2006 (Mw 7.7) and 2009 (Mw 7.3) which occurred along the Java subduction. The location of the tsunami modeling study with coordinates 6,750 LS - 7,499 LS and 106,249 BT - 106,750 BT. The study was conducted through a tsunami scenario modelling simulation generated by the potential of earthquakes in the bay area, the landslides and the combination scenario. The M6.7 and M7.3 earthquake scenarios in the direction of the Cimandiri fault with a thrust fault mechanism will drag three landslide blocks along the bay and cause a tsunami. Based on estimates, the highest tsunami is 3.8 meters in Cisolok District and the calculation of tsunami inundation to the farthest land on Pelabuhan Ratu Beach is 516 meters. Based on the worst case scenario, the tsunami level in Pelabuhan Ratu District was recorded at 2.8 m and 3.8 m in Cisolok District. The height of the tsunami based on the model scenario is classified as dangerous and very dangerous with the estimated tsunami waves arrival time around 1 minute.
