A simplified map of the geological structures of Indonesia. The tectonics of Indonesia are very complex, as it is a meeting point of several tectonic plates.Indonesia is located between two continental plates: the Sahul Shelf and the Sunda Plate; and between two oceanic plates: the Pacific Plate and the Philippine Sea Plate.

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 plate itself features an asymmetrical morphology, configured in an inverted U-shape. The arc-arc collision zone of the Molucca Sea plate is characterized as a thick, low velocity layer, which is highly variable in density. [3] [6] The variable in density of the Molucca Sea plate led to different subduction velocities on the two sides. [3]
The Molucca Sea plate has been subsumed by tectonic microplates, the Halmahera plate and the Sangihe plate. The whole complexity is now known as the Molucca Sea Collision Zone. The existence of Halmahera as a tectonic plate separate from the Molucca Sea plate is not yet entirely agreed upon by paleogeologists. Some see Halmahera as an eastern ...
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
Tectonic - Indo-Australian Plate and Eurasia Plate Major Volcanoes - Merapi , Krakatoa , Mount Sinabung , Semeru The Sunda Arc is a volcanic arc that produced the volcanoes that form the topographic spine of the islands of Sumatra , Nusa Tenggara , Java , the Sunda Strait , and the Lesser Sunda Islands .
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
