There are Pwave reflection and shearwave splitting methods when active fault is investigated using seismic methods. The Pwave reflection method is according to the fact that whether bedrock fault extends up to Quaternary strata Q3 or not, while shearwave splitting method is according to anisotropy of Quaternary strata Q3 determined by the shearwave splitting in assessing activity of bedrock fault. The Pwave reflection method can be used under the conditions of large scale bedrock fault up to Quaternary strata, whereas the shear wave splitting method can be used.展开更多
