Oklahoma earthquakes - Article Photos 1/10

Graduate student Gabriel Mattei digs beneath a box held up by Katie Keranen, an assistant professor at the OU School of Geology and Geophysics, as the two place a seismometer and this recording device into the ground on the property of Joseph and Mary Reneau Saturday afternoon, Nov. 5. , 2011. The pair are accompanied by Austin Holland, left, a research seismologist with the Oklahoma Geological Survey. They are placing the devices on the Reneau property after an earthquake rattled the area in the area in the early morning hours Saturday. The Reneaus were awakened around 2:15 a.m. when their house shook and items began falling off the walls and form shelves and cabinets inside their two-story brick ranch-style home in rural Lincoln County, about six miles northwest of Prague. Holland placed the quake's epicenter within two to three miles of the Reneau home. Photo by Jim Beckel, The Oklahoman
