GROWTH is a software for determination of subsurface anomalous density structures from discrete gravity anomaly values. It works in a context of free 3D geometry of the causative bodies. From only very general assumptions, the code determines, in a nearly automatic approach, general anomalous structures described as aggregation of thousands of small rectangular prisms.


The software is provided in a executable (growth-dg.exe) with its fortran code (.FOR file) alongside with an example to test the software.

PAF software

PAF is a software package to carry out inversions of surface deformation data (any combination of InSAR, GPS, and terrestrial data, e.g., EDM, levelling) as produced by 3D free-geometry extended bodies with anomalous pressure changes. The anomalous structures are described as an aggregation of elementary cells (whose effects are estimated as coming from point sources) in an elastic half space. The linear inverse problem (considering some simple regularization conditions) is solved by means of an exploratory approach.
