that specific quake wasnt a prophecy. altho the bilble does talk about an uprise in earthquakes and an uprise of natural disasters in "the time of the end". do some research. in all of humanities history we have NEVER seen as many disasters as we have in the last 50-100 years..... NOT EVEN CLOSE!!!!
Every time the earth shakes someone comes out of the woodwork and says that the conditions for the end times are at hands. Earthquakes, war, famine, rumors of war. It describes every year leading up to now. How many times before have been the supposed end times? Even Jesus Christ said that some people present would not taste death before the kingdom of heaven came. The real question is, what will motivate you to do good without an impending apocalypse, or a god.
Don't forget the earthquake that killed over 150,000 people in Haiti. And the one that hit Argentina around the same time as Chile. Weird! All I know is I'm ready if the time comes.
