Interesting Fact - Volcanoes

Life on Earth could be at threat from a catastrophic "supervolcano".

(Two massive piles of rock, the size of continents, are crashing together as they shift at the bottom of Earth's mantle, 1,800 miles (2,900km) beneath the Pacific Ocean.

Seismologists believe is due to erupt in between 100 and 200 million years' time.  Phew!)
