Before that the previous supercontinent was Gondwana, which formed about 600-500 million years ago, and the one before that was Rodinia, formed around a billion years ago. Sundaland, the continental core of SE Asia, is a heterogeneous collage of continental blocks and volcanic arcs bounded by narrow suture zones that represent the remnants of ancient ocean basins. The current continent and the ocean were created due to the collapse of the Pangaea and the different forces of gravity and flotation.
