Co-seismic deformation and gravity field changes caused by the 2011 Mw6.8 Myanmar and Mw6.9 India-Nepal earthquakes are calculated with a finite-element model and an average-slip model,respectively,based on the multi-layered elastic half-space dislocation theory.The calculated maximum horizontal displacement of the Myanmar earthquake is 36 cm,which is larger than the value of 9.5 cm for the India-Nepal earthquake.This difference is attributed to their different focal depths and our use of different models.Except certain differences in the near field,both models give similar deformation and gravity results for the Myanmar event.
