This film contains information about four categories of natural disaster: fire, flood, volcano and earthquake. What are the causes and effects of these natural hazards and the human response to them? This film defines each category and states that while natural disasters cannot be prevented, awareness and common sense can reduce the risks. Specifically, we look at: * Earthquakes, volcanoes, floods & bush fires. * The nature, causes and effects of these natural hazards and human responses to them. * The global distribution of earthquakes and volcanoes and their relationship with the boundaries of the crustal plates. * A case study of Wellington, New Zealand, preparing for a major earthquake.
