The Baribis Fault (Indonesian: Sesar Baribis) is a geological feature located in the northern part of Java.[1] This fault, estimated to be 100 kilometers (62 miles) long, stretches from Purwakarta to Lebak Regency[2] and is a threat to the Jakarta metropolitan area because the fault is partially located within the metropolitan area itself.

Characteristics[edit]

The fault is estimated at 100 km long and stretches from Purwakarta to Lebak Regency, moving at a rate of 5 mm a year.[3] It is a thrust fault formed during the Pliocene era.[4] It divides into two segments.[5]

Fault activity[edit]

Half of the fault is locked[6] but it caused a large earthquake in 1834 which resulted in five deaths and serious damage in West Java.[7] It sometimes causes small earthquakes.[8]

Hazard[edit]

The fault passes through the Jakarta metropolitan area, which has a population of more than 30 million, where an earthquake could cause huge loss of life and damage.[9]
