More on Earthquakes

Last month I noted the attention that several earthquakes in NE Texas in the Barnett Shale region had drawn from the media. I read an article in yesterday's New Orleans Times Picayune that the LA Department of Natural Resources is looking into it the possibility that drilling might have a seismographic impact on the region (link to article, link to print version in case previous link expires).

The issue is only beginning to be addressed, so there's no indication whether or not it will be a problem. To truly understand the potential impacts of drilling, specifically hydraulic fracturing, on the geophysics of the Haynesville Shale region will require lots of monitoring and time. There's not much you can do on the front end, and it is not a reasonable expectation for drillers to take it into consideration at this point.
