In the wee hours of Sunday morning, there was a M 2.4 earthquake in Arlington. There was also a water main break and sinkhole. You can see a video of the water main break on Facebook.
Looking on the Texas Railroad Commission GIS map, I did not find any injection disposal wells in the immediate area. Please remember that injection is injection and disposal well injection, enhanced recovery injection and fracking injection all can and have caused earthquakes. Keeping that in mind, look at the maps below that show the approximate epicenter, according to the USGS, marked in gray. Notice the intense areas of fracking just just to the south and west of the epicenter.
