6.0 Earthquake

So around 1:40am on July 4th we experienced the ripple effect of a 6.0 earthquake about 90miles from us! Most of us woke up to it, it shook the ground fairly good for about 2 seconds or so. Its the first earthquake I have ever felt, so I'll admit it was kind of cool. It did no damage to my knowledge which is great! Some of the people in my team slept right through it, those heavy sleepers!
