Earths rotational velocity? It has been said the Tsunami caused the Earths rotational velocity to speed up untill the moons tidal forces will slow it back down. Also, The tilt has been changed untill the next great quake and tsunami. No one has said if the Earths rotational velocity about the sun has slowed down or increased about the sun. Have they taken into account for this for the comet 2004 MN4 that is coming near us on April 13 2029?

I don't think that the earthquake would change the Earth's orbital path around the sun.
The Earth is very, very, very heavy. It would take more then that to have any signifigant effect.

Well if it made it spin more and tilt on its axis more then it must be powerfull enough to change the orbit somewhat. It had enough power to move all that mass.

The earthquake didn't and can't impart a change of velocity on the Earth. It merely buried a lot of mass deeper underground causing the world to spin faster -- like an ice skater pulling her arms in. The center of mass is still moving around the sun at the same rate. It would take a huge volcano shooting lava faster than escape velocity to change Earth's orbit. Lava shot out at orbital velocity wouldn't even be enough since it and the Earth would still be bound by gravity.
Now what they need to calculate is how all the asteroids that hit Earth or fly through its gravity well affect its orbit. I'm sure they are negligible but these encounters do HAVE TO have an effect on Earth's velocity.
