Inversion of Moho Depth in China Mainland from EGM2008 Gravity Data
Key Laboratory of Earthquake Geodesy, Institute of Seismology, CEA, 40 Hongshance Road, Wuhan 430071, China
Abstract 〗In this paper, the Bouguer gravity anomaly computed from EGM2008 gravity data and the varying density contrast extracted from CRUST1.0 model are used to determine the Moho depth in mainland China using gravity inversion. The results are consistent with with previous studies of Moho depth in China.
