Description:
A pilot GIS-based system has been implemented for the assessment and analysis of hazard related to active
faults affecting the eastern and southern flanks of Mt. Etna. The system structure was developed in ArcGis®
environment and consists of different thematic datasets that include spatially-referenced arc-features and associated
database. Arc-type features, georeferenced into WGS84 Ellipsoid UTM zone 33 Projection, represent
the five main fault systems that develop in the analysed region. The backbone of the GIS-based system is constituted
by the large amount of information which was collected from the literature and then stored and
properly geocoded in a digital database. This consists of thirty five alpha-numeric fields which include all
fault parameters available from literature such us location, kinematics, landform, slip rate, etc.
Although the system has been implemented according to the most common procedures used by GIS developer,
the architecture and content of the database represent a pilot backbone for digital storing of fault parameters,
providing a powerful tool in modelling hazard related to the active tectonics of Mt. Etna. The database
collects, organises and shares all scientific currently available information about the active faults of the
volcano. Furthermore, thanks to the strong effort spent on defining the fields of the database, the structure
proposed in this paper is open to the collection of further data coming from future improvements in the
knowledge of the fault systems. By layering additional user-specific geographic information and managing
the proposed database (topological querying) a great diversity of hazard and vulnerability maps can be produced
by the user. This is a proposal of a backbone for a comprehensive geographical database of fault
systems, universally applicable to other sites.
