| Natural hazards cost Australian taxpayers an average of $1 billion per year. By far, water-related disasters are the most expensive with floods, severe storms and cyclones being responsible for over 75% of the annual cost of natural disasters. Natural hazards are also responsible for significant fatalities (10 per years in average in Australia) and injuries. Compared to Australia, Australia's neighbors, from the South Asian nations to New Zealand are far more exposed to earthquakes, volcanoes, cyclones and tsunamis with severe socio-economic consequences. Risk evaluation is a pre-requisite for the implementation of measures and policies aiming at reducing the impact of natural hazards on our societies. This exercise can only be done with a robust scientific knowledge of the natural hazards, a detailed evaluation of what is exposed and how vulnerable it is. |
