The review of the geological disaster of Bandung Basin subsurface: perspective from geological approach

Abstract

The basin area is at risk of geological disaster. The Bandung Basin is a crucial part of the country’s political, economic, and social. The Indonesian Disaster Risk Index show average value of 153.85 in 2015–2020 indicates that this region is extremely susceptible to natural disasters because may disaster event happened in this location. The Bandung Basin Region is a crucial economic and political hub for Indonesia. However, its natural environment and the region’s importance as a national strategic sector are at odds with one another. Geological subsurface conditions and vulnerability content must be understood to provide an overall picture of the situation in this location. The main goal of this research is to summarize how underground conditions affect natural disasters, which is the main factor of this event. Earthquakes, landslides, and liquefaction are only a few geological disasters strongly linked to conditions below ground. Due to the Holocene sedimentary layer, the stability of the basin is threatened. All these things happen naturally: liquefaction, subsidence caused by an intercalated sand layer, and structural failure by settlement. Considering the area’s capacity and population growth, more research related to mitigation and laboratory analysis is needed to decide if this area needs to be turned into a strategic city.
