usually an earthquake is caused by techtonic plates shifting either up or down. when the plates shift down, the water rushes in to fill the gap created. This water then comes back in a steady motion and blankets whole cities.

Actually, the water recedes before a tsunami, just as it does before any other ocean wave. If you have ever been to the ocean, even with small waves, you notice that as a wave is nearing the shore, the water recedes just before the wave breaks on the shore. Generally, how much the water recedes is a function of two things, the slope of the surface leading to the shore and the size of the wave. Since a tsunami is a HUGE wave, the water recedes a GREAT amount.
