东大别地区重大地震事件深部地壳结构特征

Deep Crustal Structure Characteristics of Major Earthquake Events in Eastern Region of the Dabie Mountains

本文应用东大别地区层析成像研究结果,对研究区重大地震事件的深部地壳结构特征进行了研究,结果表明:霍山地区的2次MS≥6.0级地震在深部地壳结构上具有一定的相似性;1970年以来的12次MS≥4.0地震在25 km深度的地壳速度结构特征比较接近。

By using results of seismic tomography,deep crustal structure characteristics of major earthquake events in Eastern region of the Dabie Mountains are analyzed.The results indicate： the deep crustal structure of the two earthquakes is similar in Huoshan region;the deep crustal structure of twelve MS≥4.0 earthquakes are similar in the depth of 25 km.
