Arkansas Earthquake Strongest Since 1969
According to the U.S. Geological Survey, more than 700 earthquakes have hit the region in the past six months. Scientists aren't entirely sure why, but leading theories include the impact of natural gas drilling and a naturally occurring "swarm" or cluster of earthquakes that take place within a short span of time.
Despite the ongoing pattern of small tremors, Sunday's shaker was the biggest recorded in Arkansas since 1969. Several smaller aftershocks followed, and the event was felt throughout the state, as well as in Oklahoma, Tennessee, Missouri and Mississippi.
