Tectonic plates - Eqrthquate - Tsunami
http://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake
The crust of our planet is cracked into seven large and many other smaller slabs of rock called plates, averaging about 50 miles thick. As they move (only inches per year), and depending on the direction of that movement, they collide, forming deep ocean trenches, mountains, volcanoes, and generating earthquakes.
