I want to know the answer to the following question:
What was the magnitude of the Sichuan earthquake?
All the background I'm provided with is that "As a result of the magnitude 7.9 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes" behind the blockages; these massive amounts of water were pooling up at a very high rate behind the natural landslide dams and it was feared that the blockages would eventually crumble under the weight of the ever-increasing water mass, potentially endangering the lives of millions of people living downstream.". Is that enough to answer the question?
Answer: yes
