Sunda Plate
Type Minor

Speed1 11–14 mm/year
Features Southeast Asia, Borneo, Sumatra, South China Sea
1Relative to the African Plate

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 GPS measurements have confirmed its independent movement at 10 mm/yr eastward relative to Eurasia.[2]

Extent

The Sunda Plate 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 Celebes in Indonesia, plus the south-western Philippines islands of Palawan and the Sulu Archipelago.

The Sunda is bounded in the east by the Philippine Mobile Belt, Molucca Sea Collision Zone, Molucca Sea Plate, Banda Sea Plate and Timor Plate; to the south and west by the Australian Plate; and to the north by the Burma Plate, Eurasian Plate; and Yangtze Plate. The Indo-Australian Plate dips beneath the Sunda Plate along the Sunda Trench, which generates frequent earthquakes.[1]

The eastern, southern, and western boundaries of the Sunda Plate are tectonically complex and seismically active. Only the northern boundary is relatively quiescent.
