Earthquakes are a common act of nature, but there's just been a moderate shaker that happened in a place where quakes that are felt are not common. That begs the question why did Oklahoma get shaken by an earthquake that was reportedly felt by nearly a thousand residents?
It's been a busy year along the New Madrid Fault in Missouri. At last count, there have already been nearly 400 measurable quakes in this seismically-active region of America.
