We relocate the spatial distribution of the devastating 12 May 2008 Wenchuan earthquake and its aftershocks. The relocation database is obtained from 89 stations deployed by the China Earthquake Administration, including 54 525 seismograms from 1 376 local earthquakes over MS3.5 between 12 May 2008 and 3 August 2008. The cross-correlation technique used in this paper has greatly improved the relocation...
We have developed a new stacking technique in ambient noise tomography to obtain high-quality dispersion curves of Rayleigh waves. This technique is used to stack the vertical components of the Estimated Green Functions (EGFs) obtained respectively from cross correlation of the ambient noise data recorded by a remote seismic station and one of the short distance seismic stations of a seismic array...
