The true-life adventure story of one of the world's leading volcano experts. In 1993, Stanley Williams was investigating Galeras, what he thought was a dormant volcano in Colombia. But it blew, killing nine members of his expedition; against all odds Williams survived. This book is both the scientific story of how human beings have tried to tame these pipelines to the centre of the earth and the terrifying tale of what it is like to be caught up in a volcanic explosion.
