A tsunami is a system of ocean gravity waves formed as a result a large-scale disturbance of the sea that occurs in a relatively short duration of time. This impulsive disturbance causes vertical displacement of the water column. In the process of the sea water returning to an equilibrium position, a series of oscillations takes place, both above and below sea level, and waves, which propagate outwards from the source region, are generated.
Two days before Tsunami
This is a satellite image of the tsunami just before it hit the beach in Sri Lanka with an enlargement to show the seawater being sucked off the beach into the gathering wave.

The last picture! There are people who believe in God, there're others who don't believe, but we must understand that we're small when nature hits... This picture was taken on the banks of Sumatra Island (the height of waves was of aprox. 32m=105ft). It was found saved in a digital camera, 1 1/2 yrs after the disaster. We can't know for sure, but very likely the one who took the picture isn't alive any more (it was just a matter of sec). Today we can see the last image he/she saw before ending life on Earth!
