Time: May 12, 2008 14:28 pm epicenter: Wenchuan County, Sichuan Province Magnitude: Richter 8.0, the strongest degree of 11 degrees. For the most destructive earthquake in recent 40 years, the energy released is 2-3 times that of the Tangshan earthquake and the focal depth is 10 km ~ 20 km. Scope: More than a dozen counties and cities such as Wenchuan, Beichuan, Mianzhu and Shifang in Sichuan Province were severely affected. More than 10 provinces and autonomous regions including Gansu, Shaanxi, Chongqing and Yunnan were affected to varying degrees.
