I want to know the answer to the following question:
How did the USGS rate the earthquake?
All the background I'm provided with is that "The map of earthquake intensity published by CEA after surveying 500,000 km2 of the affected area shows a maximum liedu of XI on the China Seismic Intensity Scale (CSIS), described as "very destructive" on the European Macroseismic Scale (EMS) from which CSIS drew reference.". Is that enough to answer the question?
Answer: no
