Well, the earth's gravity is a function of its overall mass, right? The tsunami was caused by a techtonic shift (a massive earthquake) which displaces a great deal of water. However, the water was not destroyed, and the overall gravitational pull of the earth is still constant (9.8 m/s^2 baby!).

Gravity is based on mass. The more massive an object is the more gravity it has. The Moon is 1/6 the size of the Earth, so its gravity is 1/6 that of the Earth. The Thailand tsunami did not effect Earth's mass, therefore gravity is unchanged.

Yes, the increase and decrease in the depth of water as the tsunami passed over a point would have a very small effect on the measured gravity at that point.

Hi. Yes, it changed the density locally. This can be measured by how a satellite behaves as it orbits. Higher concentrations of density cause the satellite to speed up a tiny bit. It also effects the speed and rotational axis of the Earth.
