I’m already hearing people suggest that the terrible earthquake in China was unprecedented and one idiot is passing around false information stating that there are no fault lines in the area. In fact, I heard someone say they “heard on NPR” that there hadn’t been an earthquake there in 1500 years! Folks, I’ve gotta tell you - the area is certainly tectonically active, and anyone that tells you different is itching for a fight. An earthquake killed almost 10,000 people in nearly the same exact place in 1933! Most of the area is prone to mudslides and these may be obscuring some of the evidence of faults in the ancient past, but here’s a map of historic seismicity in the area since 1990. You can compare that with NY which has a relatively low amount of seismic activity since 1990 here.
