Update: Read about the Dec. 12 quake outside of Fort Worth here<\/a>.\u00a0<\/strong><\/p>\n

Another small earthquake struck outside of Fort Worth last night according to the US Geological Survey<\/a>.\u00a0 The quake was centered near Mansfield Texas, about 20 miles Southeast of Fort Worth.<\/p>\n

While it’s difficult to link any individual quake to a specific cause, North Texas has seen a significant uptick in seismic events since hydraulic fracturing technology opened up the area to widespread oil and gas drilling. Many scientific studies have linked earthquakes to disposal wells <\/a>used to store drilling liquid, including one out of UT Austin, that StateImpact Texas reported on this summer<\/a>.<\/p>\n

The seismologist uses the analogy of an air hockey table to describe what\u2019s going on. If the air is turned off, the puck won\u2019t move even if you push it. But when you pump in the air, it moves easily. With disposal wells sending fracking waste water deep underground, liquid and pressure are migrating into a \u201cstuck\u201d fault. \u201c<\/p><\/blockquote>\n

Two quakes that were strong enough to be noticed by residents struck near Dallas<\/a> in early October. No injuries or damage to property were immediately reported in the aftermath of the Mansfield tremor, reports <\/a>the Associated Press.<\/p>\n

The uptick in quakes have lead to some policy suggestions. Including surveying sites before using them for disposal wells and injection liquid into the disposal wells at a slower rate.<\/p>\n
