With the most recent earthquake in Chile, the world has again been shaken by news of a terrible tragedy, another that defies our ability to grasp its enormity. In Haiti, 170,000 are estimated to have died, with another 300,000 injured. Though it's far too early to estimate casualties in Chile, we are informed by scientists that the 8.8 (formerly Richter scale, now designated MW or Moment Magnitude scale) earthquake is the 7th strongest in recorded history and may have caused a shortening of the earth's day by about 1.26 milliseconds!
