Seventeen, the speed of movement

Yushu: Fault sliding is much faster than Wenchuan.

Wenchuan: Faults move slowly and energy accumulates slowly. Wenchuan earthquake occurs once every thousands or tens of thousands of years.

Eighteen, plates

Yushu: Ganzi-Yushu-Fenghuoshan fault zone belongs to the southern boundary of Bayankala block.

Wenchuan: Located in the north-south seismic belt, it is the dividing line between Sichuan Basin and Qinghai-Tibet Plateau, the Longmenshan fault zone, and belongs to the southeast boundary of Bayan Kara block.

19. Foreshock
