Magic2 Methodology used for the hierarchisation of Criticity Points (PCs). (DCAT-AP IT)

This document explains the methodology used by researchers belonging to the entities participating in the Magic2 Project, for the hierarchisation of Criticity Points (PC). Hierarchisation means the division of PCs into 5 main types in relation to the geological process to which they are associated: canyon/channel heads, landslides, tectonic features, volcanoes and pockmarks and the attribution to each PC of a numerical value obtained from the application of the criteria defined in the document itself. It is important to underline that the hierarchisation of PCs is relative as it occurs within each category (not to be compared with each other critical points referring to risks of different types) similar to what happens on the ground e.g. for the different natural hazards (hydrogeological, seismic, volcanic). In the Magic Project, Criticism Points have been defined one or more morpho-batimetric elements at which, in the opinion of the interpreter, a phenomenon could be generated that could cause damage to the surrounding infrastructures and/or coastal communities. The definition of PCs takes into account all available data types (historical, seismic, modeling) and is also based on the specific knowledge of the interpreters in the different areas. All this implies that the identification of PCs is extremely subjective and related to the previous knowledge and data available to the interpreter.
