Abstract

The interpretation of multiannual satellite geodetic observations after the 2010 Maule earthquake is given on the basis of the keyboard concept of the subduction region structure. It is shown that this concept, combined with the models of viscoelastic relaxation in the asthenosphere and nonstationary convection system in the upper mantle, completely explains the surface displacements observed.
