Does the degree of earth rotation changed after tsunami?
The answer to your question is most definately no. What you are probably thinking of is the earth’s orbit around the sun which was altered (very slightly) by the large earthquake which caused the giant tsunami in the Indian Ocean in Dec. 2005. The earth’s rotational tilt is thought to have been caused by a collision with a mars sized planetesimal (not just an asteroid) sometimes called Theia or occasionally Orpheus. The collision happened about 4.53 billion years ago (the earth is thought to be about 4.6 billion years old). This collision tilted the earth’s axis to about 23.5 degrees, sped up the earth’s rotation, and spread the debris that later formed our planet’s moon. It would have been spectacular to see. Then again – it is just a theory (although a very good one that is well accepted in the scientific community).
