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.
