The science on whether there's a link between oil and gas activity and a surge in earthquakes in Texas isn't clear-cut, says the new seismologist for the agency that regulates the industry here.

Over the last several years, scientists, including those at the U.S. Geological Survey and the Environmental Protection Agency, have linked an increase in earthquakes in Texas to oil and gas activity. But, industry and Texas state regulators remain reluctant to publicly acknowledge it.  Now, a study that looks at the quakes from space might put more pressure on them to do so.

Some parts of Oklahoma and Texas now have about the same risk of an earthquake as parts of California, according to the U.S. Geological Survey.

The big difference is, the quakes in Oklahoma and Texas are "induced" — they're caused by oil and gas operations that pump wastewater down into underground wells.

The shake, rattle and roll of a dozen earthquakes this week in Irving has highway crews checking bridges and homeowners inspecting homes. While there hasn’t been any significant damage to homes, some are wondering about earthquake insurance.

People in Dallas were surprised by a swarm of small earthquakes that started shaking the city a couple of days ago. There have been 11 by last count.  And the quakes, though new to the Dallas area, are just the most recent in a major upsurge in earthquakes in Texas over the last few years.

Earthquakes were pretty much unheard of in the Dallas area until 2008. Since then there have been a lot of these swarms of quakes. In Irving, Texas, where this new cluster is located, there have been more than 50 in the last several years, according to the city manager. This current swarm started around September.
