From out of the sky, from under the earth, from far out at sea - disaster comes. We build and invent new things - and sometimes bring disaster on ourselves. Today television and the Internet mean that we can watch disasters as they happen, and see their terrible results.

From Pompeii to the Asian Tsunami, from the Great Fire of London to Chernobyl, the stories of disasters are frightening, but they have much to tell us. Disasters bring stories of fear, pain, loss, and death - but also of people whose extraordinary bravery and feeling for others will touch your heart.
