Geologist Susie Beiersdorfer has discussed the connection between Youngstown earthquakes and the nearby injection well. She has said the brine toxic waste injected into the well reactivated an ancient fault by acting as a lubricant and reducing friction between layers of the shale, thereby causing earthquakes, meeting organizers said.
The situation in the Youngstown area has attracted extensive national and local media attention.
The Dec. 31, 2011, earthquake shook Youngstown and reportedly was felt in several states and as far away as Ontario, Canada.
The earthquake may have awakened many more citizens to the serious health and safety issues reported by those living near fracking and injection wells and to reports of drinking-water source contamination, meeting organizers said.
