The Eruption That Nearly Wiped Out Humanity: Toba, 74,000 Years Ago | Documentary for Deep Sleep

Seventy-four thousand years ago, the largest eruption our species has ever lived through dusted a continent in ash and dimmed the sun for years — and for decades, it was blamed for nearly wiping us out. The truth the rock keeps is stranger, and a great deal quieter. A slow, careful telling of the Toba super-eruption, made for a long night. We follow it from the magma gathering beneath Sumatra and the afternoon it let go, through the ash, the sulphur veil, and the uneven winter that followed, to the people who walked through it half a world apart — and the famous near-extinction that, on the evidence we can actually dig up, never quite happened. Mechanism over melodrama, in a voice pitched just above a whisper.
