Doesn't say anything about the axis of the earth off by 6 degrees, or the days being shorter.
Their detecting a wobble, but that will probably steadily drop off after a few months or years and the earth will return to a normal orbit. Perhaps the quake did change the orbit in some way permanently, but I don't think it was enough to impact the days by 15 minutes, or change anything we'll ever notice.[/quote:8d781]

However, due to tidal effects of the Moon, the length of a day increases by 15 µs every year, so any rotational speedup due to the earthquake will be quickly lost. Similarly, the natural Chandler wobble of the Earth can be up to 15 m (50 ft).

I've read the 1 inch measurement elsewhere too.
