Abstract

The 2008 Wenchuan earthquake is one of the largest and deadliest events of the last century, both in terms of victims and seismically-triggered geo-environmental hazards. The combined effects resulting from the seismic activity of 2008 led to major damages in several domains of the local society, including the built environment and the social component, highlighting the extensive gap related to resilience measures aimed at both prevention and recovery in case of a disruption. Thus, it is imperative for the development of a multi-objective and comprehensive formulation for resilience combining holistically all the diverse facets of a local community. To this regard, this paper presents a wide-spectrum analysis and preliminary findings, being structured in working threads specifically addressed in the context of an ongoing project (REACH). The focus is on the built environment damage analysis following the field work which took place in December 2016 in the Wenchuan territory, involving 3D laser scanning activity of 7 high-risk areas and the related audit and preliminary structural analysis of the damage. As a result, a set of external and internal factors have been identified as possible key causes of the surveyed damages. Of these, external factors mainly relate to environmental and hazardous properties, whereas internal indicators involve structural features as well as building regulations.
