- [Narrator] 252 million years ago, a catastrophe killed nearly all life on earth.
- This is the closest our planet has ever been to going back to square one.
- As many as 90% of species across the earth died.
(tense music) - This extinction was much greater than the one that ended the age of the dinosaurs.
- [Narrator] But an asteroid wasn't to blame.
The culprit was lurking just beneath the surface.
Deep beneath Northern Pangaea, (tense music) superheated liquid rock, magma, is rising.
It pushes up against the Earth's rigid upper layer, the crust, until it can take no more.
The crust splits open.
Within hours, the local landscape is torn apart.
Cracks grow, forming great curtains of fire.
As lava floods onto the surface, the insides of Earth spew out.
