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 ...
Indonesia is a country located close to tectonic plate boundaries which causes it to have many active faults and is prone to earthquakes, [1]
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 .
[1] In this model, the Bird's Head and Halmahera plates are separated by the Sorong Fault, a major lateral east–west fault. An earlier model considered the area to be the Halmahera Arc, a volcanic arc of islands without a tectonic plate base. More recent studies in the 1990s and later, have displaced this theory with the Halmahera plate ...
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]
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.
