Although the tsunamis had a force of hundreds of megatons of TNT, this is somewhat small when it is up against the momentum of the Earth's rotation, the Earth will not come to a screeching halt, but a leap second in atomic time (UTC) might be necessary sooner than expected. It will be interesting to see what the results from the International Earth Rotation and Reference Systems Service (IERS)(http://www.iers.org) published each Thursday.
