From Denny: On the Richter scale this earthquake was a hugely powerful "7." What does that mean in explosive power of Mother Nature? Try 35 times more powerful than one atom bomb. The quake lasted a long full minute when most quakes last only a few seconds. This is why there is so much devastation.
There is a long lateral fault that runs through Haiti and scientists had warned the country they were at risk for a huge earthquake. It has been 200 years since the country experienced this scale of disaster and this type of magnitude quake tends to run in 200 - 250 year cycles according to geologists.
