A swarm of earthquakes rattled Arkansas early Monday, June 6, according to the U.S. Geological Survey. At least six quakes were detected within the same northeastern region, with the first kicking off just seconds after 2 a.m., USGS data show.

The first was a 2.4-magnitude earthquake, followed by a 2.3 about two minutes later, and a 1.9 after that — all 5 miles or less southeast of Williford. Around 2:06 a.m., geologists detected a 1.7-magnitude quake, then a 2.1 magnitude southwest of Ravenden, by roughly 4 miles.

Everything was quiet for a little over four hours, until a final 2.0-magnitude earthquake started at 6:30 a.m., 5 miles southeast of Williford, data show. Though the quakes were not particularly strong, several people reported feeling “weak” and “light” shaking to the USGS.

According to the Observer, Some residents took to Twitter to see if others felt anything. “We heard them and felt them in Cherokee Village,” one user wrote. “I was just woken up by my bed shaking,” wrote another, claiming they felt the tremors all the way in Fayetteville. “Was that an earthquake???” No damage was reported.
