摘要： 根据陕西省及邻省地震台网的地震记录,利用地震及工矿爆破的首波走时,采用地震层析技术,重建了渭河断陷及邻近地区的莫霍界面速度图象。并对速度横向不均匀性及其与地质构造、地震活动的关系进行了探讨。
关键词: 首波, 地震层析成象, 莫霍间断面, 波速构造
Abstract: In this paper,using travel time data of head waves from natural earthquake and industrialexplosion recorded by local seismic network in Shaanxi Province and adjacent areas,the velocitvimage of Moho discontinuity beneath Weihe fault depression and adjacent areas is obtained bymeans of seismic tomographic technique.Then the relationship between the lateral velocity het-erogeneity and geological structures and seismicity is discussed.
Key words: Head wave, Seismic tomography, Moho discontinuity, Velocity structure
