More information on earthquakes, injection wells

By Bob Downing Published: April 21, 2012

Numerous stories were filed this week after federal researchers presented a paper on earthhquakes and fracking-waste injection wells at a national conference in San Diego.

Researchers think increased seismic activity in the central United States including Ohio is tied to wastewater injected below ground by the oil and gas industry, said William Ellsworth of the U.S. Geological Survey.

"Something unusual is going on, and we think many of these earthquakes can be traced to industrial activity," he said.

A total of 13 small earthquakes have struck the Youngstown area in the last 13 months and are believed tied to a now-closed injection well in Mahoning County.

An abstract of the USGS study was published earlier and the full report will be released this summer.

From 1970 to 2000, there were on average 21 earthquakes a year in the U.S. mid-section.

That jumped to 50 in 2009, 87 in 2010 and 134 in 2011, accordinjg to the study.

Earthquakes were also reported in Colorado, Texas, Arkansas, New York, New Mexico and Nebraska and possibly in Oklahoma, Louisiana and Missiissippi.
