Chilean Earthquake Likely Shifted Earth's Axis

NASA geophysicist Richard Gross has some alarming facts about the recent Chilean earthquake.

  • The quake moved the Earth’s axis about 2.7 milliarcseconds (or 8 centimeters, or 3 inches)
  • Due to the quake, each day from now on will be about 1.26 microseconds (millionths of a second) shorter
  • Santa Maria Island (an island in Chile) may have been raised as much as 2 meters (6 feet) because of the quake

As I like to say, “snap crackle pop!”
