The continent would have been a dangerous place, covered in volcanoes and exposed to regular earthquakes.'Mauritia acted as a buffer zone between the western Indian subcontinent and eastern Madagascar, and was fragmented by numerous tectonic and volcanic events that occurred in that region since the early Cretaceous,' the authors said.It is thought Mauritia separated from the rest of the continent around 60 million years ago.
It materializes in varying degrees of intensity for the same two weeks every year.
Volcanoes can also form where there is stretching and thinning of the crust's plates, e.g., in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America.
