The Great Sumatran fault, also known as Semangko fault, is a large strike-slip fault running the entire length of the island of Sumatra.This Indonesian island is located in a highly seismic area of the world, including a subduction zone off the west coast of the island.
The tectonics processes in Indonesia formed major structures in Indonesia. The most prominent fault in the west of Indonesia is the Semangko Fault or the Great Sumatran Fault, a dextral strike-slip fault along Sumatra Island (about 1,900 km). The formation of this fault zone is related to the subduction zone in the west of Sumatra.
Indonesia is a country located close to tectonic plate boundaries which causes it to have many active faults and is prone to earthquakes, [1]
The Great Sumatran fault is a 1,900 km (1,200 mi) strike-slip fault system located on the island of Sumatra. The fault is divided into about 20 segments. [6] The Great Sumatran fault was the source of the 1994 Liwa and 1995 Kerinci earthquakes. It produced its largest earthquake during the 1943 Alahan Panjang sequence; measuring M s 7.8. [7]
Mount Besar (Indonesian: Gunung Besar, means: Big Mountain) is a stratovolcano in the southeast of Sumatra, Indonesia.A minor sulfur deposit can be found in the crater.A big solfatara field called Marga Bayur is located along its north–south-west flanks or the Semangko fault system.
The island of Sumatra lies on the convergent plate boundary between the Indo-Australian plate and the Eurasian plate.The convergence between these plates is highly oblique near Sumatra, with the displacement being accommodated by near pure dip-slip faulting along the subduction zone, known as the Sunda megathrust, and near pure strike-slip faulting along the Great Sumatran fault.
