Your editorial of Jan. 16 stated that "To our knowledge there have been no credible reports linking such facilities (injection wells) with earthquakes."
However, the Charleston Daily Mail on Jan. 12, 2012 reported that W.Va. Department of Environmental Protection spokeswoman Kathy Cosco stated that when the amount of fluid being injected was reduced, the Braxton County earthquakes stopped in 2010. On January 10, 2012, a 2.8 magnitude earthquake was recorded. Coincidentally, the amount of water being injected into the well was increased. Ms. Cosco said, "It makes it appear there's some type of connection."
The New York Times on Feb. 5, 2011 reported that an Arkansas Geological Survey researcher stated there is "strong temporal and spatial evidence for a relationship between these quakes (in Arkansas) and the injection wells." The same article refers to hundreds of earthquakes recorded in Colorado a few years after the Army began injecting fluids into a disposal well near the Rocky Mountain Arsenal. (1966).
Just look at the injection well located near the Dallas-Ft. Worth Airport. Over 175 earthquakes occurred in 2008 and 2009. Activity at the well has stopped and so have the earthquakes.
I just think there are credible reports out there.
