The U.S.G.S reports that an earthquake registering 3.5 on the Richter scale struck in Irving Texas and was felt in downtown Dallas.

Local news sites took to twitter to report...

Some think it could be from "Fracking" projects in the region? Here is an interesting piece on "Why Earthquakes Happen".

Seismologists set up earthquake-monitoring devices in Irving, Texas this week after a series of tremors shook the site of the former Dallas Cowboys football stadium. Irving was hit by a 2.4-magnitude earthquake on New Year’s Day, the 17th recorded in the city since September. The seismic series has raised questions about the cause in the area that has seen an uptick in quakes over the last several years. Some residents believe the implosion of Texas Stadium in 2010 may have exacerbated problems. There is also speculation the quakes might be related to hydraulic fracturing, or "fracking," an energy extraction technique that has a long history in north Texas.
