Experts Looking At Whether Fracking A Factor In Texas Quakes

Jan 9, 2015

Geophysicists are looking at whether hydraulic fracturing, generally known as fracking, might be one of the factors responsible for a number of quakes to hit Texas earlier this week. Fracking is a process through which liquid — generally chemicals and sand suspended in water — at very high pressure is blasted into wellbores to fracture the shale rock layers and release natural gas. Also this week, a study from the Bulletin of the Seismological Society of America linked dozens of earthquakes in Ohio in March 2014 to fracking in the area. A previous study in Oklahoma had linked the wastewater shot into deep disposal wells to a surge in quakes there.

People felt two small but noticeable earthquakes in the Dallas area Tuesday, with reports of shaking buildings and flickering lights. Some residents said they felt nothing; some worried about fracking; others joked about it all.

The first quake was measured at 3.5 magnitude, according to the U.S. Geological Survey, and the second was measured at 3.6. Both of them were centered about 3.5 miles east-northeast of Irving, just outside of Dallas.

As the legislative year begins, a major watchdog group for the Edwards Aquifer has claimed some successes for 2014 and said it would be keeping a close eye on what lawmakers did this year.

The Greater Edwards Aquifer Alliance, a coalition of 51 community, religious, environmental and business organizations that want to create a more impactful voice for the environment and the aquifer, has stated that it would be following state legislation carefully to make sure the coalition retains its ability to advocate for the environment.

If it's getting close to Christmas, it's also getting nearer to the year's worst allergy season for San Antonio and the Texas Hill Country.

Copious amounts of cedar pollen are expected to blow in on the first cold front, draping yellow blankets of the dusty stuff on cars and other surfaces.

It’s been over 4 years since the Deepwater Horizon explosion and BP oil spill. The underwater gusher pumped crude into the Gulf of Mexico for 87 days and is considered the worst maritime oil disaster in history. The US Government estimated the total discharge at 5 million barrels. But that number is uncertain and there are some reports that the well site continues to leak oil into the Gulf.

In November 2012, BP and the Department of Justice reached a settlement and in part agreed to a record-setting $4 and a half billion dollars in fines and other payments.
