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 complex biogeography of the Indo-Australian Archipelago is a result of its location at the merging point of four major tectonic plates and other semi-isolated microplates in combination with ancient sea levels. Those caused the isolation of different taxonomic groups on islands at present relatively close to each other. Wallace's line is ...
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]
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 .
The Sunda plate is a minor tectonic plate straddling the equator in the Eastern Hemisphere on which the majority of Southeast Asia is located. [1]The Sunda plate was formerly considered a part of the Eurasian plate, but the GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to Eurasia.

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.
