Make no mistake — the Chilean earthquake was massive. It was over 500 times stronger than the eathquake that hit Haiti — the salient difference being that it hit out in the ocean, near — but not in 00 a region that has earthquake preparedness (building codes, etc).
How massive was the Chilean quake?
Well, it threw the Earth off its axis.
By about 3 inches. Making the day about 1.26 microseconds shorter (1 microsecond = 1 millionth of a second).
Still, it's not as bad as the 2004 earthquake that created the tsunami in the Indian Ocean. That shortened the day by 6.8 microseconds.
