The scope of this research is to present the types of geological hazards, including the area coverage that influenced them. Starting with studying the geological conditions of the Sirenja area, then identifying and mapping the types of hazards that occur. Five types of geological hazards hit the Sirenja area at that time, namely due to surface rupture faults, earthquake shocks, liquefaction effects, tidal flood inundation, and tsunami. Thus, September 28, 2018, is a time that marks the Sirenja area is prone to several geological hazards, and at any time or without knowing when a natural disaster like this will occur again.
