Residents living in northeastern Arkansas were jolted awake at 2:15 a.m. by a major earthquake. The shaking was felt as far away as New England and Canada. Scientists estimate that this event measured 7.0 to 8.0 in magnitude. This marked the first in a series of powerful earthquakes to shake the region over a three-month period.
