This CD-ROM shows illustrative examples of catastrophes and includes interactive chapters. Using striking examples (Mt.St.Helen, hurricane Andrew, the earthquake in Kobe, floods along the Mississipi) and specific use of multimedia elements, the user learns everything about the causes of earthquakes, volcanism, storms, floods and erosion. The alarming scale of such incidents is shown in numerous pictures and movies. In addition interactive chapters allow the simulation of the possible dimensions of rising sea-level or shifting climate zones.
