History

The past. With the sea about 120 metres lower, about 80,000 square kilometres of today’s shallow seas on this plate were dry land, a sixth of its sea: the wide shelf off the mouths of the Irrawaddy, and one Andaman island about four times the size of today’s, which never reached the mainland. The land was already dry when the timeline begins; the rising sea drowned most of it between 15,566 and 8,496 years ago. The lines that stand for the shallow sea turn to the colour of land, all at once, and only across those spans.

4 million years ago: Seafloor spreading began in the Andaman Sea, splitting this plate from Sunda.
