汶川大地震同震新构造活动特征和地震破坏程度的初步调查与认识

Coseismic Neotectonism and Seismic Failure during the Wenchuan Major Earthquake

汶川Ms8.0级特大地震波及半个亚洲,震撼整个中国。本文通过在灾区的实地初步调查,对龙门山同震新构造活动、发震断裂构造和地表破裂的分布、产状、强度、继承性复活与新生特征、新构造活动与地震地质灾害的关系等进行了初步总结,并探讨了同震新构造活动对地震破坏程度的控制与影响。

The Wenchuan major earthquake affected a half of Asia and shook almost the whole of China. This paper deals with coseismic neotectonism, causative fault and distribution, occurrence, intensity, inherited reactivation and rejuvenation of the surface rupture as well as relation of neotectonism with seismic damage during the Wenchuan major earthquake, and makes an approach to control of the seismic damage by coseismic neotectonism.
