| Abstract: | Taking Manila trench subduction zone as an example,this paper has a research on the gravity anomaly of subduction zone with wavelet analysis.Through Symlet wavelet multiscale analysis of the data of gravity anomaly and topography around the subduction zone we have found that there is a close relationship between gravity anomaly and topography in the fourth or the fifth scale of high frequency,and surmised that the seawater influences mainly in the second and the third scale of the high frequency of gravity ... |
