Comparison of Early Aftershock Forecasting for the 2008 Wenchuan MS8.0 Earthquake

Wenchuan earthquake of May 12, 2008 in Sichuan province is most destructive, the most widely spread, the most difficultly to disaster relief in recent decades in China. The earthquake relief and reconstruction work is also the fastest, to mobilize the widest range of input power in an action, creating a miracle of the world's earthquake relief and reconstruction. Those successful practices provided a valuable experience reference to other areas for fight against natural disasters and rebuild their homes. This article describes the damage of housing, roads, bridges and other engineering structures and landslides mudslides, dammed lakes and other geological hazards triggered by earthquakes; Outlines the effort of the rescue operation, including personnel search and rescue, road rehabilitation, caring for the wounded, people placement and soon; Summarizes the reconstruction strategies and policies, including with Chinese characteristics” counterpart support” reconstruction mode which means a province to help a county. In the end, the article discusses the earthquake relief and reconstruction experience and inspiration.

Wenchuan Ms8.0 Earthquake

We use the movement velocities of GPS stations in western Sichuan province, China, to determine the distribution of horizontal strain accumulation before the 2008 Wenchuan Ms8.0 earthquake with a piecewise approximation approach and the coseismic displacements to determine the fault slips of the earthquake with an inversion analysis method. The results show that the distribution of the principal strain rates is strongly related to the active faults in the region, but along Longmenshan fault where the earthquake occurred, the strain rates are much lower than the others. The fault slip distribution shows mainly a thrusting with dextral striking, and the fault slips in the upper parts of the fault plane are in general bigger. Using the current strain accumulation rate and the released energy by the earthquake, we predict such a big earthquake in Longmenshan fault zone will happen in 460 to 1380 years.
