There is a technical term for these earthquakes, "induced seismicity” or man made earthquakes. It would be better to use the proper terminology rather than categorize these particular quakes with all others. They aren't the same and quite frankly, over time, these are more dangerous to human health. They carry a category that relates to human health differently than just the ground shaking. This is about chemicals as well as ultimately liquefaction.
There is a quality of any legitimate geological study in securing the understanding of water sources. In the case of "Induced Seismicity" there are human health imperitives that result in compromised ground water sources. Use the words, it matters. "Induced Seismicity" has an entirely different value system than the 'normal' earthquake. It is more than tremors. Tremors aren't chemically or hydraulically (water pressure) induced.
RENO (Texas) (CBSDFW.COM) – There have been more than 300 earthquakes (click here) reported in Parker County since December, according to just-published research conducted by an earthquake study team.
In preliminary findings released Wednesday, the team reported that the quakes show a complex fault system in the area near Reno and Azle, which started experiencing quakes for the first time in November.
The progress report from the SMU North Texas Earthquake Study said the relation of the quakes to two nearby waste-water injection wells remains a major question. Preliminary locations for the earthquakes show them occurring within one to two kilometers of the well sites.
The U.S. Geological Survey has stated wastewater disposal into deep geologic formations is a likely contributing factor to an increase in quakes. The USGS issued a joint earthquake advisory with the Oklahoma Geological Survey Tuesday, because of hundreds of temblors there....
These quakes are minor in magnitude, however, they are numerous. The more and more cracks there are can lead to greater instability. Once there is a larger magnitude the entire area could result in damage in a chain reaction to these smaller cracks.

PARKER COUNTY — Remember (click here) the images of Parker County residents whose water wells catch on fire? Now they say their problem has gone from bad to explosive.
They also say they have the test results to back up their assertions.
A handful of Parker County residents said it all started around 2009 when their tap water started to bubble and stink.
Their curiosity flowed into suspicion.
Their suspicion evolved into disgust.
Their water wells were filling with volumes of methane gas. Logic told them two newly drilled natural gas wells near their homes were to blame....
