Battelle has a report about Injection- Induced Earthquakes
ISSUES RELATED TO SEISMIC ACTIVITY INDUCED BY THE INJECTION OF CO2 IN DEEP SALINE AQUIFERS - it says the Anna fault earthquakes happen at 10 kilometers or deeper - this link also talks about the effect of supercritical CO2 on geology
This next link to the OhioSeis site (The Ohio Seismic Network ) - it says earthquakes in Ohio happen at a depth of 3 - 6 miles ...... which is much closer to the depth of the proposed injection well for our area.
