SEVERE VOLCANISM

INTENSE TECTONICS

Osiric explosion

As the major plates are all converging into each other over the Centralia and Osiric hostpots, great pressure is suddenly released and a great deal of fresh material is quickly ejected out into the surface to form new land mass and completely disrupt the climate, triggering mass-exinctions and therefore the end of the Primazoic and the beginning of the Mesozoic.
