VISCO1D-v3 is a program package to calculate quasi-static deformation on a layered spherical Earth from a specified input source (fault plane parameters) at specified points on the surface or at depth.

It uses a spherical harmonic expansion of the global deformation field and evaluates a sum of viscoelastic normal modes in a semi-analytic computation.

Version 3 of VISCO1D-v3 is now available (updated on Jan. 29, 2007).
