Yesterday earthquakes were the two of the most powerful earthquakes that the region has felt since 1976. There were no instant reports of injuries, casualties or major damage associated with the earthquake. Shaking lasted for around 2 seconds and a small crack was caused in 1 police officer's wall and another officer’s television was knocked as per dispatchers in Greenbrier. Several people who felt earthquake but did not have any damage call 911. On the website of the survey over 2,300 people reported feeling 4.7 quake.

Greenbrier felt dozens of quakes over the past 6 months or more. In southern Missouri and northwest Mississippi there was at least 1 report of it being felt. Geologists are searching whether the recent series of quakes is led by pressurized liquid injected into the ground by natural gas drillers or if it is a natural occurrence. Last week, other earthquakes were also recorded by U.S. Geological Survey but they were not felt by residents. On Friday, scientists recorded at least 10 quakes starting with one registering at 1:10 a.m. of 2.4 magnitude.
