Hengduanshan Mountain Range Situated at the juncture of Tibet, Sichuan and Yunnan in the southeast of the Qinghai-Tibet Plateau, it has an average elevation of 2,000 to 6,000 meters (click here). Its highest peak, Gonggashan, is 7,556 meters above sea level.
That is just the mountain range elevations and doesn't account for the continental crust below the range where the friction point was that caused the epicenter to be defined.
