Natural hazards - AQAHazard risks and consequences
The two main types of natural hazards are tectonic and climatic. Natural hazards can have economic, social and environmental consequences. The risks of these occurring can vary greatly.
Hazard risks - economic, social and environmental consequences
Hazards can have economic, social and environmental consequences. For each hazard event the risks, or probability, of a particular consequence occurring can vary greatly.
This depends on certain factors. For example in a developing country, the death toll tends to be high but the short-term economic costs are often relatively low, whereas in a developed country, the death toll tends to be low but the short-term economic costs can be extremely high.
The long-term situation is more complex. Developing countries can be slower to repair damage to roads and buildings. This can lead to a reduction in tourists and therefore a long-term loss of valuable income.
Hazard risks are increasing due to population growth, urbanisationA growth in the urban population, usually resulting in the extension of towns or cities., pressure on marginal landLand that is difficult to develop and yields little profit. and changes to the natural environment.
