摘要
研究区域地壳速度模型是地震学研究中的经典问题,而震中位置和震源深度的准确确定与地壳速度模型密切相关。论述了中国各区域测震台网速度模型的现状,并分别以福建和内蒙古地壳速度模型的地震定位结果为例,说明合适的地壳速度模型对于准确测定地震参数的重要性。
How to get the appropriate crustal velocity model is a classical problem in seismology research.And the accurate determination of the epicenter and the focal depth is closely related to the velocity model.This paper briefly introduces the present situation of the velocity model of the seismic network in China,and selects earthquakes took place in Fujian and Inner Mongolia as examples to explain the importance of the appropriate velocity model for the accurate determination of earthquakes.
