Baribis Fault

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

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

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

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]
