Was there a global flood? Or maybe he will still be? What forces could cause a global cataclysm, or is it the property of myths? This book is about disasters in the history of the Earth, about natural disasters that hit people in the past and threaten humanity in the future. In it you can find a variety of information: from the first legends about the worldwide flood to modern hypotheses and theories; about what the scale, causes, rhythms and consequences of great disasters are; about how they were imprinted on the earth's surface and in the memory of mankind.
