Seismologist John Armbruster • Discussing the recent string of earthquakes in Ohio. If you live in that state, you might have noticed up to a dozen small earthquakes since last spring. There hasn’t been a measured earthquake in the area ever until last March. Apparently, the disposing of waste water into the ground (during a energy-releasing process called “fracking”) may have flowed into an earthquake fault line. This same problem has happened in Oklahoma, Texas and Arkansas. In Arkansas alone, 1,000 mini-quakes were measured. source(via • follow)
