An earthquake recorded in Trumbull county Sunday afternoon is once again raising questions about shale-related injection wells.

The United States Geological Survey said that a low-level 1.8 magnitude tremor was centered along DeForest Townline Road. A few people who live near the site tell 21 News they felt a bump or movement but not enough to cause any damage. The 9-11 dispatch center says it did not receive any calls related to the quake.

The epicenter is within a mile of two brine injection wells along North Main Street. YSU geology professor Dr. Ray Biersdorfer says it's a valid question to consider. “They started injecting this spring at these two injection wells about a mile away and now we've had at least the first earthquake”, said Biersdorfer.

Last March, a series of earthquakes in Poland Township resulted in a moratorium on drilling and fracturing. In 20-11 dozens of earthquakes caused a shutdown of an injection well in Youngstown. The professor says new wells are now being monitored by the Ohio Dept. Of Natural Resources.

“One of the benefits of what happened in Youngstown is they should respond in a more timely fashion, because they have four portable stations there testing before the injection began and after the injections”, said Biersdorfer.

Earlier reports said ODNR had not detected any out of the ordinary seismic activity.

 A spokesman for American Water Management Services, owner of the wells, said they did not yet have enough information to make a statement
