Simulating intensity shake maps given the parameters on the location and the intensity of an earthquake for the Etna volcano area

This Addendum Report is given as documentation and guidelines for the use of the software implemented to simulate intensity shake maps given the parameters on the location and the intensity of an earthquake for the Etna volcano area. The software is delivered as executable codes (compiled in FORTRAN) for PC environment with some examples for training in the use. The software has to be intended as a research tool and used by expert users. There are two modules to accomplish the chain of the computation. For the presentation of final refined maps GIS tools have to be used.This work was funded by the Italian Dipartimento della Protezione Civile in the frame of the 2007-2009 Agreement with Istituto Nazionale di Geofisica e Vulcanologia (INGV) - Project V4 FLANK Volcanology.Unpublished4.1.
