Document Summary
How to mitigate a (geological) hazard- minimize damage and loss of life/injuries. Similar approach used for all types of risks. Scenario: the government of ontario proposes to build a nuclear reactor on the shore of. Our task: carry out a risk analysis and risk management study for the government, focused on seismic risk. Hazard: something which may cause harm to people (death/injury/property damage) Water- drinking water, hydroelectricity (resource) or flooding, ice storm (hazard) Damage threshold: when a resource becomes a hazard. Partly by empirical observations and scientific studies. Ultimately by societal preferences (i. e. choices) o consider pollution. The very notion of pollution is culturally dependent. We define what is or is not pollution. Over time, there may be changes in human tolerance/sensitivity to the hazard. Snow (within threshold) + wind (within threshold) = blizzard (hazard) Each on its own might be a resource an no problem, but together produce a hazard.
