Description:
We present GEOFIM (GEOphysical Forward/Inverse Modeling), a WebGIS application for
integrated interpretation of multiparametric geophysical observations. It has been developed to
jointly interpret scalar and vector magnetic data, gravity data, as well as geodetic data, from GPS,
tiltmeter, strainmeter and InSAR observations, recorded in active volcanic areas. GEOFIM gathers
a library of analytical solutions, which provides an estimate of the geophysical signals due to
perturbations in the thermal and stress state of the volcano. The integrated geophysical modeling
can be performed by a simple trial and errors forward modeling or by an inversion procedure based
on NSGA-II algorithm. The software capability was tested on the multiparametric data set recorded
during the 2008-2009 Etna flank eruption onset. The results encourage to exploit this approach to
develop a near-real-time warning system for a quantitative model-based assessment of geophysical
observations in areas where different parameters are routinely monitored.
