用折射波S_n走时反演渭河断陷及邻近地区的莫霍面速度

SEISMIC VELOCITY IMAGE OF MOHO DISCONTINUITY BENEATH THE WEIHE FAULT DEPRESSION AND ITS ADJACENT AREAS OBTAINED BY INVERSION OF TRAVEL-TIME DATA OF S_n WAVES

根据陕西及邻近省区地震台网的地震记录，利用莫霍面折射波Sn的走时资 料，重建了渭河断陷及邻近地区莫霍间断面的速度图像，并对方法的稳定性及结果的 可靠性进行了探讨。

By inversion of travel-time data of S_n waves from natural earthquakes recorded by local seis- mic network in Shaanxi Province and adjacent areas, the velocity image of Moho discontinuity be- neath the Weihe fault depression and adjacent areas is obtained. Then stability of the used method and reliability of the results are discussed
