The first photography represents a flood creates by strong pluies.we can observ that there is water on part of the street because it is not right. It there be a person with medium of water I think that it be leave of to it because its house be full of water. This flood with been able to be caused by thaws out it ices in mountain and when the ground water overflows. For me there should be more effective system of prevention to envisage the floods in order to warn the inhabitants so that they can prepare or evacuate. The cities should be equipped with system of pumping to evacuate water most quickly. The second photography represents a beach where took place a violent tidal wave because one can observe in the second plan water overflowing on villages.

Natural disasters like the creates flood and tidal wave the death of many people in the world what involves diseases. They are creates because of the climatic change and the effect of greenhouse. from 1980 to 2000 there was an increase in these catastrophe due to the climatic change and with the effect of serre.Il tidal wave and of flood has more and more there as we can noted the ave the tsunami in Indonesie. I am afraid of these catastrtophes natural because one does not know when they arrive and that creates many human losses.
