Study: Connection between quakes, gas drilling
FORT WORTH, TX
The dozen minor quakes were reported in a few Dallas suburbs
from the fall of 2008 through last spring -- and another dozen too
small to be felt were detected by equipment. The largest was a
3.3-magnitude quake, and no major injuries or damage were reported.
The Southern Methodist University and University of Texas study
says the quakes occurred during the time wastewater from the gas
extraction process was injected into a deep disposal well near the
quake sites.
The study does not include information about last summer's
series of quakes in Cleburne, about 50 miles southwest of Dallas.
