S1·E4 Ocean of Volcanoes

Witness the birth, growth and death of an island in the greatest ocean on Earth. Millions of years are condensed into an hour revealing unforgettable images of an erupting underwater volcano; rivers of lava exploding below the waves; roads and houses buried by molten rivers of rock. From these violent beginnings emerge coral reefs of unparalleled richness supporting large groups of grey reef sharks and giant manta rays.
