Short summary

Recovering from major earthquakes is a challenge due to a destablized environment. Over 11 years, we monitored a region hit by the Wenchuan earthquake, finding the loss caused by postseismic hazards was more than that caused by the earthquake. The main reason was a rush in reconstruction without proper hazard and risk assessment. It was concluded that postseismic recovery should consider not only spatial but also temporal dynamics of hazards as well as possible interaction among hazards.
