Keep it in perspective, the 4.1 magnitude that hit Arkansas this morning is small and earthquakes in this part of the country are infrequent. There was one in Texas and Oklahoma recently and Arkansas is a part of the same general real estate.

There may be local damage, and yes people can die from falling off a ladder that is shaken by a quake, but all in all, this is just a normal Earth movement. Just to the north, however, is the New Madrid fault. When that puppy rolls it could be enormous, and it will someday.
