Abstract:

Sunda Strait Tsunami took place on 22 December 2018. Two days later a post survey was conducted in the area surrounding the strait, along the coast of the Banten and the coast of Lampung. The results of 28 measurement points revealed that the tsunami height varied from 0.75-6.22 m. The maximum height was measured at the area of Carita in Banten, based on a tsunami trace which left broken tree branches. Tsunami height measurements took the tide level into consideration. In some areas the distance of tsunami inundation was investigated by means of the post tsunami survey. In general the average of inundation distance was approximately 200 m from the coastline to inland. The Krakatau Volcano tsunami modeling was simulated to reconstruct the tsunami propagation and to verify tsunami modeling method. The model was generated considering a flank collapse of the Volcano. Based on the eyewitness interviews no earthquake shaking was felt before the tsunami.
