Madagascar plate - Wikipedia
The Madagascar plate or Madagascar block is a tectonic plate holding the island of Madagascar. It was once attached to the Gondwana supercontinent and later the Indo-Australian plate. Rifting in the Somali Basin began at the end of the Carboniferous 300 million years ago, as a part of the Karoo rift system.

Madagascar Plate - African/Arabian Tectonic Plates
Madagascar was once a part of the supercontinent Gondwana but between 160-117 Ma, it began separating - rifting southward over 1000 km away from the Africa plate. This displacement occurred along the currently inactive Davie Ridge transform fault off the west coast of Madagascar running through the middle of the Mozambique Channel (Witt et al ...

2016年11月28日 · Madagascar, the big island off the east coast of Africa with the lemurs and baobabs, is thought to be sitting in the middle of an old tectonic plate, and so, by the rules of plate tectonics, should be tectonically quiet: few earthquakes and no volcanoes. But it’s not.

East African Rift System is slowly breaking away, with Madagascar ...
2020年11月20日 · The region of distributed extension is about 600 kilometers (372 miles) wide, spanning from Eastern Africa to whole parts of Madagascar. More precisely, Madagascar is actively breaking up with southern Madagascar moving with the Lwandle microplate — a small tectonic block — and a piece of central Madagascar is moving with the Somalian plate.
Study on the East African Rift System: Madagascar will split into ...
Preceding surveys suggest that the system consists of narrow zones in microplates that experience extension and deform separately from the major tectonic plates. The research team collected data from seismic stations situated in Madagascar, Eastern Africa and in other islands to derive the characteristics of the complex rift system.
