Shakemap 1-6-2015

Update 9:50 pm:  The neighbor who took the video you are seeing tells me: “I think it is related (to the earthquake), it happened right after the first earthquake, not 2 hours like the city told Robert Wilonsky, it is at the intersection of Hughes and Dykes Way.” He also tells me that whatever caused this break, “the city water and ATOMS gas crews are out there right now, it is still gushing”. I may go up and grab some pics. Stay tuned.

Update: that water main break is near Preston and Churchill Road.

Did you feel those two three tremors today?

Two of them were widely felt, with the first affecting just Irving. The second quake, which was around 3:10 p.m. and centered around the former site of Texas Stadium, was a 3.6 magnitude quake that was felt from East Fort Worth to East Dallas. The third, which happened at around 6:52 p.m., was a 3.6 magnitude aftershock with an epicenter just northeast of Irving. Some homeowners have reported minor damage, including cracks in drywall and gaps in moulding, while 33 City of Dallas water mains are flooding streets.

While some people will claim that these quakes could be naturally occurring due to their proximity to the Balcones Fault, there is a growing body of evidence that human-induced changes to the structure of the earth’s crust is causing these seismic shake-ups in North Texas. We’ve talked previously about fracking and disposal wells, and whether it can affect home values, but with today’s strong quakes, we’re hoping to find out whether or not this phenomenon is a lasting one.

Just this week, researchers from SMU have started placing sensors in the ground in Irving, hoping to root out the cause of the frequent earthquakes that seem centered in the Dallas suburb. According to this report, there have been 18 earthquakes in the Irving area since Nov. 1. The question is, if the cause is found to be manmade, will homeowners insurance cover the damage? And should we all invest in additional earthquake coverage now that I can feel the tremors all the way over in Casa Linda?
