Through which measures can cost benefits be gained? In that example benefits are gained through three different actions. First through the implementation of a risk management, second through a risk transfer to insurance companies and third to rehabilitation and compensatory component.

Chart shows the cost benefits through mitigation measures on the example of a landslide. It shows that only a certain effort in mitigation measures gain cost benefits. If to less measures are taken, the frequency and the impact of the events are still too high and a better optimum can be found. If too many measures are taken, the cost of mitigation and management will outnumber the gained benefits!

The actual risk for a country to suffer in a long term from a natural disaster depends on the actual exposure but also on the vulnerability of a society (how can they cope and adapt to the event). Central America as well as big parts of Africa and Asia are at high risk to suffer for a long term from natural disasters.

The chart compares 2 earthquakes and their different results for the countries. The number of deaths for Haiti is far higher (higher population density and a lesser standard of living, worse conditions after the event). However, the material loss for Chile was higher due to a bigger economy but the actual impact of the economy was far less due to a higher GDP, quicker response and better measures after the event. Different factors of a country decide about the long-term impact of a natural disaster .

The grafic shows the economic impacts for different countries. Even so that a lot of disasters hit the US the economic loss is insignificant. South Americas well as the Asian Regions, Africa and India are far more vulnerable for such events.

Earthquake and Tsunami in Japan 2011 on the first place with a total damage of about 230 billion dollars. Equal cost damage of natural disaster have different impacts on economies depending on their economic power (GDP)!

The frequency and the costs of natural disaster, which are linked to the climate change are constantly increasing (storms, extreme temperature, droughts, floods...) . The global loss reached 375 billion dollars in 2011, which equals about 0.5% of the global world product.

As well as the number as the damage amounts increased in the last 30 year. Reaching a total damage of 200 billion dollars in 2011 (about 1.3% of the US gross domestic product)

Most of the shown natural disaster happened on islands, near the sea and at tectonic borders.  Overall loss ranges from 8 - 125 billion USD. Damage partly insured. Earthquakes, Tsunamis and Hurricane have the biggest potential to destroy facilities.
