The author has written this book with the purpose to make a general work on natural hazards that synthesizes it in an accessible and sufficiently comprehensive form. He has tried to transcend the boundaries of disciplines while describing the, in essence very multidisciplinary, nature of geophysical and hydrological hazards.
It is always the difficult dilemma with books on natural hazards. Should it focus on certain aspects of the hazard (its probability of occurrence, its damage potential, the effectiveness of mitigation measures and building codes, its human behaviour and injury causation during the catastrophe, etc), or should the book be presented as a complete entity which involves physical, technological, economic and social realities? The author has chosen for the second option, although he does present now and then parts of the first option.
Many books on natural hazards too often fall to an anecdotal level of 'horror stories' lacking a serious academic treatment of the subject. Although the author includes many case studies in his book, he describes them in a very accurate and objective way. Alexander holds professorships in Massachusetts and in Italy (Siena and Urbino), and therefore many studies from Italy are presented in the book.
The author finishes his book with a chapter on international strategies against disasters. He reviews the national policies, which vary from disaster relief, to technological adjustments, to comprehensive damage reduction, to multiple hazard management. Also the worldwide strategies of the UN (resolution 42/169 of 1987) adopting the IDNDR of the 90s (International Decade for Natural Disaster Reduction) are highlighted.
The sections on risk analysis in the book are interesting, although a bit outdated. Since the publication of the book in 1993 there has been a major step forward in the risk assessments of structures subject to extreme environmental loads.
