My Blogs (olelog) are mainly based on my daily reading of earth science news.
Here on whatonearth.olehnielsen.dk I try to weave some of the pieces together to a greater whole with added background info.
The Sunda Plate is located in southeast Asia and commonly considered a part of the Eurasian Plate.
The Sunda includes the South China Sea, the Andaman Sea, southern parts of Vietnam and Thailand along with Malaysia and the islands of Borneo, Sumatra, Java, and part of the Celebes in Indonesia. Also included is the seismically active western Philippine Islands. The Sunda is bounded by (clockwise from the east) the Philippine Plate, the Bird's Head microplate (western New Guinea); the Molucca Sea, Banda Sea and Timor microplates; the Australian Plate; the Burma Plate; the Eurasian Plate; and the Yangtze Plate to the north.
The eastern, southern, and western boundaries of the Sunda Plate are tectonically complex and seismically active. Only the northern boundary is relatively quiescent.
The Sumatra fault spans the entire length of Sumatra. The Sumatra fault is a strike-slip fault, where two sections of rock pass horizontally by each other in opposite directions (shown by arrows on the map).
On the landsat image to the left the Fault zone is clearly visible as a light line to the left of Lake Toba, which is filling one of the earths largest calderas - 35x100 km wide. See my post on the Toba Super-Eruption.
