Earthquake in Christchurch, New Zealand

Quite recently, a 6.3 earthquake has struck the city, Christchurch. The aftershocks were counted as 5.5 and 5.6. Hundreds of victims are injured and some are still stuck in the rubble of the aftermath. This terrible disaster occured early afternoon at Tuesday, just before 1 P.M. Multiples of fatalities occured, such as the Anglican Cathedral collapsing.

For one of the questions, it says to say how the earthquake occured. Since we're learning about Greek mythology, I'm going to explain about it in a mythologic way. :) Atlas, the strongest of the all the Titans, was sent (after being defeated by Zeus and his family) to carry the vault of the sky on his shoulders. Whenever Atlas was tired, and shifted the sky onto the other shoulder, it apparently creates a earthquake. Now, in 5th grade, I remember reading this book, and it says whenever the plates of the Earth shift and overlap eachother, it creates in earthquake. :)
