Introduction
Every year, more than 500 disasters are estimated to strike our planet, killing around 75,000 people and impacting more than 200 million others. In 2012 thirty nine ‘disasters’ have already happened (January to April), killing almost 702 people and affecting thousands of people all over the world[1]. The economic and human impact of the disasters in the last 12 years (2000-2011) is: 1.1 million people have been killed, 2.7 people have been affected and there was 1.3 trillion (USD) damage in the economic area. The numbers show the effects of natural disasters such as earthquakes, floods, and hurricanes, as well as manmade disasters such as chemical accidents[2].
