I ve just used EM-DAT* to check the disaster trends by continents.
The number of disasters
The number of death
The cost

You can see the general trends. This clearly shows Asia is the most vulnerable continent.
As mentioned before, there are no disasters if there are no people. Also, we can notice that
disasters change from human sufferings to economic damages with the development process
of the countries.
