There are more and more floods every decades. The increase of floods could also be caused by the increase of the sea level due to climate change

map of people impacted by geological disasters such as earthquakes. The most country affected are Japan, India, Africa, South America, Middle East. This also relates to the previous images, which shows along these countries the strongest seismic activities.

Earthquake which can cause tsunami as well.  We can see that the strongest are located near Japan, Indonesia, and Andes. Mainly earthquakes happen where different plates crash. You can see that in the image, where the red dots occur.

Repartition of Tropical depression in the world, we can see the most impacted area like Japan or the Gulf of Mexico. The map shows the past 150 years of hurricanes on earth until 2005. As you can see, the most powerful hurricanes of category five appear in the area around Japan. This is due to the high sea temperature in this region

Increase of natural disasters in Europe (European Economic Area) during the same period.  In average, there seem to me more meteorological as well as hydrological events. This can be for example floods or storms. 

Evolution of natural disasters in the United States about 1980 to 2008. The number of events more than doubled since 1980. We can see that the Meteorological and climatological disasters are maybe coordinate with the climate change. This disasters are for example storms, which is shown in green, or extreme temperatures, which is shown in yellow.

This image should visualize that natural disasters will not decrease and it is important to start adapting measurements.

The image shows a risk map of India, which was developed using a geoinformation software. The map uses historical data to visualize the past storm areas.

Remote Sensing can be used in various ways to develop emergency plans as well as mitigation plans before a disaster happens.

This image shows an example of a Disaster Alert with historical as well as real time data. It is possible to receive an update as soon as there is a warning for a disaster.
