Earthquake Axis Shift
The 8.8 earthquake in Santiago, which killed hundreds and affected millions across Chile, may have also resulted in a Pole Shift, NASA scientist believe. The cause of the axis shift is due to the fact that epicenter of the quake was located in the Earth's mid-latitudes and the fault which caused the quake cuts through the Earth at a steep angle. This resulted in a vertical slip of the Earth's mass, creating a move in the Earth's axis by 8 inches or 3 cm, and a day which is now 1.26 milliseconds shorter.
