چکیده

Abstract

The Wenchuan earthquake is a natural disaster. Its occurrence and aftermath have demonstrated the critical roles of seismology and earthquake engineering in reducing seismic hazards and damages. However, their existing limitations should also be underscored. This article summarized and reviewed the current scientific understanding of earthquake ruptures, and new insights gained since the Wenchuan event. This study focused on the related challenges to seismology and earthquake engineering as follows: (1) The under-estimation of earthquake risks before occurrences; (2) The current limited data regarding large earthquakes in continental thrust fault systems; (3) The causal relationship between the Wenchuan earthquake and the reservoir impoundment in its vicinity; (4) The identification of low-velocity zone in the crust and its seismogenical role; and (5) The casualties and economic losses from a cascade of diverse natural hazards triggered by the ruptures, and the excellent earthquake resistance associated with tunnels in mountainous terrain.

6. Conclusions

In observance of its 10-year anniversary, there are many lessons which can be learned from the Wenchuan earthquake event of 2008. A broader context of understanding of continental dynamics is still required in order to gain correct assessment results of earthquake risks, as well as to effectively mitigate seismic hazards. The existing huge earthquake-related fault structures and underground low-velocity zones need to be revisited for the purpose of recognizing their roles in seismic activities. A new reasonable hazard assessment model which focuses on both direct and secondary hazards should also be established. Moreover, the relationships between human activities and earthquake events still require effective resolutions. Also, the generalizations of better building codes and transportation methods in the mountainous terrain need to be given sufficient attention. These all definitely will present scientific challenges for seismology and earthquake engineering in the future.
