This book is an introduction to hazards and man-made hazards which have implications for engineering geology. It examines hazards such as seismic effects, volcanoes and floods, and with subsidence, waste disposal and ground water pollution. Geological Hazards is an essential book for professional engineers in civil, geological and planning areas worldwide.
