"MARIETTA, Okla. -- The ground had been shaking for a week, on and off, when the biggest of the earthquakes hit. People here heard two loud booms. Then the picture frames started falling. Wendy Gillham turned to see her flat-screen television crash to the floor only a foot or so from her infant girl. Then she looked outside and saw her chimney in pieces on her driveway."
"'I was a wreck,' she said of the panicked moments that day in late September.
Suspicion in this southern Oklahoma community near the Texas border focused on a new neighbor just across Interstate 35, an injection well for disposal of oil and gas wastewater. When the well shut down a few days later, the shaking stopped."
