Geo-engineering lessons learned from the 2008 Wenchuan earthquake in Sichuan and their significance to reconstruction
The Wenchuan earthquake of 2008 is only a memory of very recent past, but has already left lasting consequences to geo-environments. Differing from general point-quake-triggering source, the Wenchuan earthquakes quake-triggering source extended along an active fault of hundred-kilometer-long. Wide spread of mountain bodies was shaken loose during the earthquake. Consequently landslide and debris flow geohazards are dominating factors in planning postdisaster recovery and rebuild. This paper presents lessons from coping with various geohazards and disasters. We also describe geological factors in relocating disaster areas residents. We discuss necessity of establishing a national emergency management system for huge scale catastrophe, earthquake precursor identifications, town construction to keep away from active faults, town safety with high risk of seismic and geological hazards, importance of geohazard investigation and remediation for quake-loosened mountain bodies. We also describe geological factors in risk reduction in the quake disaster area, site selection for settling spots, infrastructure reconstruction, and the earthquake relic-site selection and protection.
