C'mon - can fraccing really cause an earth quake? Earth quakes are movements of the earth structures.

There is a huge difference between fracing and injection for water flooding or thermal recovery. Fracing (for stimulation) is a short duration (few hours or days), relatively low volume (3-30 thousand barrels) event. Long term injection in waterfloods, disposal wells and geothermal projects have a duration of months to years and high volumes per well in the range of 1 million to tens of million barrels. There were a series of earthquakes here in Denver during the 60's associated with radioactive water disposal from the Rocky Flats facility that lubricated a fault. The earthquakes stopped as soon as injection stopped. 30 miles to the east of Rocky Flats is the DJ Basin field with 10s of thousands of wells, all fraced. No earthquakes. see the last section tulane.edu
