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.

Large numbers of earthquakes of smaller magnitude occur very regularly due to the meeting of major tectonic plates in the region. Based on the records of the USGS, Indonesia has had more than 150 earthquakes with magnitude > 7 in the period 1901–2019.
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 islands of Indonesia constitute an island arc that is one of the world's most seismically active regions, with high velocity plate movement at the Sunda Trench (up to 60 mm (2.4 in) per year), and considerable threats from earthquakes, volcanic eruptions, and tsunami throughout.
With an area of 60,000 km 2, and depths up to 15 km, the Kutai is the largest and deepest Tertiary age basin in Indonesia. [1] Plate tectonic evolution in the Indonesian region of SE Asia has produced a diverse array of basins in the Cenozoic. [2] The Kutai is an extensional basin in a general foreland setting.
Indonesia has relatively high tectonic and volcanic activities. It lies on the convergence between the Eurasian , Indo-Australian , Pacific , and Philippine Sea plate . The Sunda megathrust is a 5,500 km long fault located off southern coasts of Sumatra, Java and Lesser Sunda Islands, where the Indo-Australian Plate is thrusting northeastward ...
Banda Arc tectonic map. The Banda Arc (main arc, Inner, and Outer) is a dual chain of islands in eastern Indonesia that is around 2,300 km long. It is the result of the collision of a continent and an intra-oceanic island arc.
