Seismotectonic deformations related to the 2010 Maule earthquake at different stages of the seismic cycle from satellite geodetic observations

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 nonstationar...

Description
Summary: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.
