They danced around many caveats to be correct regarding waste-water injection and I almost misread it as THE largest: The largest human-induced quake was the 8.0 Sichuan China May 2008 "pre-Olympic"--quake caused by the water loading on a fault running beneath a hydro-electric dam: A dam and reservoir built specifically to collect carbon-exchange credits. Whats 90k dead in exchange for all those carbo-dollars which will flow in from the liberal Western governments? The weight of the water was not calculated until after the quake--equivalent to several dozens of cubic kilometers of ice.

Strong Earthquake Caused By Human Actions Say Researchers
Posted: Mar 23, 2014
A large November 2011 earthquake near Prague has been linked to human activity according to a USGS press release.
The 5.7 magnitude earthquake is thought to be the largest human-caused earthquake associated with wastewater injection.
Scientists had previously drawn a link between wastewater injection and a 5.0 magnitude quake that occurred on November 5, 2011 near active injection wells.
Now they suggest that the 5.0 quake caused a 5.7 magnitude quake less than 24 hours later which ruptured part of the Wilzetta fault system.
The first one is thought to have increased stresses in the fault system and the second to have set the stage for thousands of aftershocks.
