The Lembang Fault is a large active fault situated less than 10 km from the major population centre of Bandung. Geological evidence has suggested that large earthquakes have occurred on this fault in the past, and therefore may occur in the future. This map shows a simulation of what scientists believe is the largest earthquake that could occur on the fault. It is clear that this event would cause widespread damage but it is still not known how likely such an event would be. One of the aims of the Indonesian Earthquake Hazard Map is to improve the understanding of the likelihood of events like this.
