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.
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 ...
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 .
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.
Molucca Sea Collision Zone modified by Zhang et al. [3] using GeoMapApp The Molucca Sea plate is one of many tectonic features that compose the Molucca Sea Collision Complex, which refers to the tectonic relationship of the Sangihe plate, Halmahera plate, and the Molucca Sea plate, in addition to the volcanic Halmahera and Sangihe Arcs.
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)
The tectonic setting of the Molucca Sea region is unique. It is the only global example of an active arc-arc collision consuming an oceanic basin via subduction in two directions. The Molucca Sea plate has been subsumed by tectonic microplates, the Halmahera plate and the Sangihe 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.
