North Texas Dallas Nine Earthquakes - Nine earthquakes which ranged from magnitudes 1.6 to 3.6 rattled North Texas in less than 24 hours. The North Texas Dallas nine earthquakes late Tuesday and early Wednesday had experts turning to seismic data to help determine the reason for the cluster of quakes, with fracking suspected as one of them.

The U.S. Geological Survey recorded the North Texas Dallas nine earthquakes in Irving, a Dallas suburb, according to Fox News.

The first of the North Texas Dallas nine earthquakes was recorded to be a magnitude 2.3. It reportedly hit around 7:37 a.m. local time Tuesday, centered near the former site of Texas Stadium, the former home of the Dallas Cowboys.

Around 3:10 p.m., the second of the North Texas Dallas nine earthquakes was reported by KDFW viewers in Irving, Dallas, Mesquite, Arlington and Coppell. This time it was stronger and recorded at a magnitude 3.5

The third quake, reported to be the strongest in the area in recent weeks, followed just minutes before 7 p.m. and with a magnitude 3.6

The fourth temblor of the North Texas Dallas nine earthquakes was a magnitude 2.9. It hit at 8:11 p.m., while the fifth, of a magnitude 2.7, happened just a minute later at 8:12 p.m.

They were followed by the sixth of the North Texas Dallas nine earthquakes. This one was of a magnitude 1.7 quake and occurred at 9:54 p.m.

The seventh was a magnitude 2.4 at 10:05 p.m., and the eighth a magnitude 1.6 at 11:02 p.m.

The last of the North Texas Dallas nine earthquakes was confirmed occurred at 12:59 a.m. Wednesday with a magnitude 3.1.

All of the temblors were reported to be centered in Irving, except the sixth one.

According to Irving police, there were no reports of injuries or major damage in the 11 earthquakes that hit since Tuesday. However, they have requested the public to stop 911 calls just to report the shaking, unless someone was hurt or there was another emergency, reports the Associated Press.

On Monday, Southern Methodist University seismologists started installation of equipment to monitor the recent quakes.

Before 2008, there had been only one reported earthquake in the Fort Worth Basin, but as 2008 came, there were a reported more than 100 quakes in North Texas. This high number of frequency in earthquakes in the area has led some to wonder if increase in fracking was a cause for the cluster of quakes.

A seismologist from SMU, Dr. Brian Stump, told KDFW that fracking is not yet part of the discussion as to the cause of the North Texas Dallas nine earthquakes. However, disposed wastewater is not being ruled out.

"When they recover the oil and gas, there's fluids with ... there's water with that, and they have to separate the water, and then they have to dispose of the water," said Stump. "Historically, it has shown that in some places that they've triggered small to moderate earthquakes." 

The North Texas Dallas nine earthquakes has left residents on edge, wondering if the situation could only get worse, according to Mail Online. Small earthquakes have reportedly become more common in Texas and Oklahoma. In October, Texas officials have amended rules for disposal well operators as high-pressure injections related to hydraulic fracturing, or fracking, can trigger earthquakes, has caused much concern.
