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.[2]
Extent
The Sunda Plate includes the South China Sea, the Andaman Sea, southern parts of Vietnam, Myanmar, Laos and Thailand along with Malaysia, Singapore, Cambodia, southern Philippines , and the islands of Bali, Lombok, West Nusa Tenggara, Borneo, Sumatra, Java, and part of Sulawesi in Indonesia.
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 also known as Java Trench, which generates frequent earthquakes and tsunamis.[1]
The eastern, southern, and western boundaries of the Sunda Plate are tectonically complex and seismically active. Only the northern boundary is relatively quiescent.
