I want to know the answer to the following question:
Who published a Seismic Risk Analysis Study?
All the background I'm provided with is that "In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region.". Is that enough to answer the question?
