Tremor centered here
Many Lawrence County residents were startled awake in the early morning hours on Monday by a series of micro earthquakes that began at approximately 1:38 a.m. The United States Geological Survey reported that the three earthquake’s epicenter was in the Walnut Ridge and Hoxie area.
The first tremor measured 2.0 on seismic equipment, the second tremor and the strongest of the three occurred at 4:52 and measured 2.9. The last tremor measured 2.2 and occurred shortly after 5 a.m.
The micro earthquakes were felt as far away as Illinois and the United States Geological Survey reported over 70 responses to the "did you feel it survey"F on their website. Many of the reports were from Lawrence County, but reports of feeling the earthquake also came in from as far south as Greenbrier in central Arkansas, and as far north as Carbondale, Ill.
Although there were many reports of shaking, the tremors were not strong enough to cause structural damage. The Arkansas Department of Emergency Management has taken the opportunity to remind residents that while earthquakes that are felt in the area are typically minor, an earthquake of a greater magnitude could result in significant damage. The ADEM recommends that families have an emergency plan should a major earthquake occur.
