postseismic
1. Relating to or ocurring during the time following an earthquake.
2. Frictional afterslip or deformation following a seismic event.

After a large earthquake, postseismic deformation may result from earthquake-induced slip along the plate interface, commonly referred to as "afterslip", and as viscoelastic relaxation in the volume surrounding the fault rupture.

The well-positioned postseismic observations can probe the mechanical properties of subduction megathrusts and the media that surround them.
