"But that’s not Oroville’s only problem: It is also associated with one of the largest “induced” (induced or promoted by actions of man) earthquakes ever recorded in the U.S.: A M=5.8 event in 1975 (According to the USGS). While this may sound like a foreign concept, the filling of some reservoirs has been shown to be associated with a significant increase in seismicity. Most frequently, this increase occurs within several months of a reservoir’s filling. However, at Lake Oroville, it occurred seven years after the dam’s completion (Lahr et al., 1976)."
