The current episode of BBC R4 "Inside Science" spends about 30% of its alloted 30 minutes on the subject of Human Induced Earthquakes" the biggest of which (alledged) is the 7.9 one in Wenchuan, 3 Km from the newly built and filled large dam. I think nature can outdo a lake.

They point to the the Human-Induced Earthquake Database that collates "peer-reviewed articles" for inclusion. Interestingly at physics.org they say:

"The more important trend is that between hydraulically fractured boreholes and unusually large earthquakes, most likely related to the reactivation of pre-existing geological faults."
