In his latest book "The Angry Earth. Natural Disasters", Boyko Rangelov examines the processes associated with natural disasters, mainly in the solid Earth (earthquakes) and its liquid shell (tsunamis). The materials on the potential threat of a tsunami in the Black Sea and its possible consequences, archaeoseismology studies, and the results of studying natural disasters in Antarctica are up-to-date. The latest data on earthquake hazard in Bulgaria are presented, on the specific behavioral reactions of groups of people who find themselves in extreme situations, on the microseismic zoning of Sofia - as a main tool for reducing the negative consequences of an earthquake. The recently modern early warning systems and systems for rapid assessment of the consequences of strong earthquakes are examined. The book will be useful for specialists, teachers and students, as well as for the general public interested in natural disasters.
