摘要
本文利用穿透1906年沙湾8.0级地震震源区及其附近地区的8条石油人工地震反射剖面资料,对大震震源附近地区进行了分层速度反演,并分别计算了部分地层的层速度,对大震震源附近地区浅层速度分布特征作了较为深入的探讨。所得结果表明,大震震源附近地区的浅部地壳速度明显低于其外围地区。
This paper reported the stratified velocity inversion on the areas around the large earthquake source computed the interval velocity of part of strata respectively, and discussed thoroughly the distributive features of the shallow velocity around the large earthquake source by using the data of 8 petroleum man-made seismic reflection profiles cross the focal region of the 1906 Shawan earthquake MS = 8.0 and its vicinity. The results obtained show that the velocity in the shallow crust in the vicinity of the large earthquake source is obviously lower than that in its outer zone.
