| Abstract: | 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 precision by giving much more accurate P-wave differential travel-time measurements than those obtained from ... |
