A massive earthquake has hit off the coast of Chile. According to the United States Geological Survey (USGS), the quake hit today (April 1) around 7:46 PM EDT or around 23:46:45 UTC. The quake registered as a preliminary 8.0, but was upgraded to a 8.2. What does a 8.0 earthquake mean? It means it has so much energy that it is roughly equivalent of releasing over 6 million tons of TNT. Quakes with intensity higher than 8.0 are extremely rare, and usually occurs once a year on average.
