Anatural disasteris a normal phenomenon of nature that affects the society and environment.A natural physical event that kills people (directly or indirectly) or exceeds local capacity to control damage or initiate recovery efforts
The situation or event which overwhelms local capacity, necessitating a request to national levelfor external or international assistance. "
This means that the situation or event overflows the capacity locally, showing that not only the In the case of the United States, assistance for extreme events is linked by law to the disaster declaration issued by the president.
Current situations are presented in the last partof the century and no doubt can help to interpret the number of disasters has increased.
Floods and flash floods should be avoided completely while overflows can be accepted if the payback period is high.
Mass movements
Most mass movements affecting limited areas can be avoided if the threat is identified in advance. Other affecting large areas or entire valleys, so try to avoid the threat is costly.
Active faults
The risk is local, so the known faults should be taken into account in territorial planning.
Tsunami
Because the risk affects only the lower coastal area, in many places is relatively easy to move investments to higher ground.
High volcanic risk
The slopes of active volcanoes are obviously areas that should be avoided.
Adapt
You can not avoid the threats that do not vary much spatially. However, some of these can be successfully mitigated, i.e., one can adapt to the threat. Including:
Earthquakes
These can be mitigated by implementing appropriate building codes, as is often the failure of buildings that bring harm and death. Another side effect is the mass movements triggered b...

...risk contributors.
Possible areas could be setting interest rates according to the areas of risk and level of mitigation, or just to have as a condition for state loans to build housing and in approved areas with certain rules.

Natural hazard data used for the purpose of reducing the risk in two ways: either directly guiding the way to a decision, as the home buyer, builder, or indirectly influencing their decisions through regulations, standards or varying interest rates or insurance rate according to risk level. Depending on the option chosen, the data may be available free or for a price.

Sell the data to a high cost is one end of the scale. The logic of this would be that risk awareness is propagated to all citizens through the insurance prices or availability or do not pay for housing. We are not aware of an example where this has been shown to be effective.
