Importance of rheological heterogeneity for interpreting viscoelastic relaxation at a subduction earthquake

Guest post by Hisashi Suito Postseismic deformation is commonly observed following large earthquake. This postseismic deformation is thought to be caused by three mechanisms: afterslip, viscoelastic relaxation, and poroelastic rebound. Short-term deformation near the rupture zone is considered to be caused mainly by the afterslip or, at times, poroelastic rebound. It is commonly interpreted that… Read more »
