It has been a year since the devastating Wenchuan earthquake struck Sichuan Province, China on May 12,2008,which caused tremendous casualties,geological disasters and economic losses.With a deep feeling of grief at the sight of the shattered world in quake-stricken areas,geologists and geophysicists once again profoundly felt their heavy responsibilities for geo-hazard prevention and reduction,and resolved to make their due contributions-what we,as scientists,could do for the quake relief efforts and post-quake reconstruction and what scientific explanations we could offer to the public for the occurrence of the devastating natural disaster.
