625-203 Dangerous Earth

At least one of Earth sciences 625-101, 625-102, 625-103 or 600-201 is recommended.

This subject provides an introduction to the study of natural hazards on the Earth on various spatial and temporal scales. It will cover hazards of geological and meteorological origin, as well as major catastrophes such as those produced by extraterrestrial impact and climate change. Topics will include:

• earthquakes and their consequences;

• tsunamis in the ocean basins;

• volcanoes and volcanic activity;

• land instability and mass movements;

• floods, drought and fire;

• thunderstorms and tornadoes;

• tropical cyclones;

• extraterrestrial impacts and mass extinction;

• climate change and its implications for human populations;

• managing and reducing the risks from natural hazards.

At the end of this subject, students will have acquired a detailed understanding of the nature and causes of natural hazards, be informed of the linkages between these, know the potential effects of various kinds of natural disasters for human populations and activities, and have an appreciation of what can be done to manage and minimise the dangers posed by natural environmental hazards.
