The United States Geological Survey has confirmed that a small earthquake occurred overnight just southwest of the Washington County Airport. Details are sketchy but government officials say the quake occurred just before three a.m. and registered a 2.2. magnitude. Residents in and around the area were posting on Facebook overnight that they had felt their homes shaking and some items in their homes moved. There was no damage reported and no known injuries. Earthquakes of such magnitude cause little damage and are barely felt, USGS geophysicist Julie Dutton said. If you felt it, you can go online and report the intensity to the USGS.
