• This is the 4th AstroGeo Seminar. In the continuation of the last talk of Dick Peltier, we have now the presentation of Giorgio Spada, on

Love numbers, the “sea-level equation” and the glacial isostatic adjustment problem by Giorgio Spada

Dipartimento di Fisica e Astronomia (DIFA), Settore Geofisica, Università di Bologna, Bologna, Italia.

Giorgio has made publicly available several tools for the computation of the Love numbers and the resolution of the Sea Level Equation. Here are the links to these tools :

Free computer programs for the simulation of GIA are all based on the assumption of spherical symmetry: •

• Love numbers calculators ALMA, the alternative Love numbers calculator (v. 2.2): Spada, 2008.

Surface loading solvers (and Love numbers calculators)
