Thrust fault in the Qilian Shan, China.The older (left, blue, and red) thrust over the younger (right, brown). The Glencoul Thrust at Aird da Loch, Assynt in Scotland. The irregular grey mass of rock is formed of Archaean or Paleoproterozoic Lewisian gneisses thrust over well-bedded Cambrian quartzite, along the top of the younger unit.
The Flores back-arc thrust fault is a major system of west–east trending thrust faults that extend eastwards from west of Lombok just south of where Sunda Shelf ends at Bali Sea, towards the islands of Sumbawa, Flores, and Alor, with a total length of at least 800 km., [1] entering the Weber Basin and Aru Basin adjacent Sahul Shelf of the Australian plate.
However, seismologists also attribute the earthquake to shallow crustal faulting associated with a back-arc thrust fault running along the island. The Barbiris Fault which runs east–west south of Batavia (present-day Jakarta) may have been the source of the earthquake, with a magnitude of 7.0 to 8.0.
A thrust fault is a type of reverse fault, in which the rock above the fault is displaced upwards relative to the rock below the fault. This distinguishes reverse faults from normal faults , where the rock above the fault is displaced downwards, or strike-slip faults , where the rock on one side of the fault is displaced horizontally with ...
Off the north coast of Bali is the Flores back-arc thrust fault, located in the back-arc region. It formed due to the convergence between the Sunda and Australian plates, accommodating compression. The two plates converge northward at a rate of 80 mm (3.1 in)/yr, in which the Sunda megathrust takes 70 mm (2.8 in)/yr of the movement.
A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults.

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.
