How did tectonic plate movement cause the Indian ocean tsunami?

Answer:
Two plates, the Indian plate and the burma plate (a section of the eurasian plate), slipped, forcing the Indian plate underneath the burma plate, as the Indian plate had a thiner crust and less buoyancy (floatation) than the burma plate. This caused the burma plate to move upward pushing vast amounts of water up, causing the tsunami.
