Induced Seismicity

As is the case elsewhere in the world, there is evidence that some central and eastern North America earthquakes have been triggered or caused by human activities that have altered the stress conditions in earth’s crust sufficiently to induce faulting. Activities that have induced felt earthquakes in some geologic environments have included

• Impoundment of water behind dams, 
• Injection of fluid into the earth’s crust,
• Extraction of fluid or gas, and
• Removal of rock in mining or quarrying operations.

In much of eastern and central North America, the number of earthquakes suspected of having been induced is much smaller than the number of natural earthquakes, but in some regions, such as the south-central states of the U.S., a significant majority of recent earthquakes are thought by many seismologists to have been human-induced. Even within areas with many human-induced earthquakes, however, the activity that seems to induce seismicity at one location may be taking place at many other locations without inducing felt earthquakes. In addition, regions with frequent induced earthquakes may also be subject to damaging earthquakes that would have occurred independently of human activity. […] —USGS

Two More Quakes Strike North Texas

STAY TUNED for Important Announcements Concerning the State of Texas Starting Late 2014

18 Earthquakes strike North Texas in 23 Days

16 of the quakes measure greater than M2.5 with the largest two recorded as magnitude 3.6Mw.

More than 80 minor shocks have occurred in the built-up areas of Johnson, Ellis and Parker counties in the last five years.

In May 2001, after a 3.3Mw shock occurred in Northern Texas, FIRE-EARTH Blog said: Texas quake likely caused by oil and natural gas drilling activities

Texas and Fracking

Oil and gas drilling rigs are moving ever closer to populated areas in Texas, causing air quality problems for the residents. “Today there are over 12,000 gas wells in the Barnett Shale surrounding the Dallas-Fort Worth area. In addition to the wells, infrastructure such as compressor stations are springing up near the drill sites, adding to air quality problems. In towns like DISH, TX – where 11 high-pressure gas pipelines and their associated compressor stations all converge – residents have reported serious health impacts and severely degraded air quality.” —EarthJustice
