An M_W6.3 earthquake occurred in oft-com:office:smarttags" />Damxung, Tibet, on October 6th, 2008. The authors determined the fault parameters using a descending coseismic interferogram from ENVISAT ASAR images. In addition，  examined the uncertainties in the InSAR-derived source parameters using the variance-covariance matrix of InSAR data points estimated with a 1-D semivariogram function. The inverted results showed that the earthquake occurred on a secondary fault in the eastern margin of the Yangyi Basin, with a strike of 178°, a dip of 58° and dipping to west, which was normal faulting with a little of right-lateral strike slipping.
