This document is a map (geotiff) representing the Critical Points (CP) mapped in the Magic1 project and their hierarchy (performed in the Magic2 project). In particular, this map shows the sector of the eastern Tyrrhenian Sea, the southern Adriatic Sea and the central-northern Ionian Sea. By hierarchy we mean the subdivision of the PCs into 5 main types in relation to the geological process to which they are associated: canyon/canal heads, landslides , tectonic features, volcanoes and fluid leakage (Pockmark). In addition to these there are two typologies represented which are PCs that cannot be classified due to lack of data and PCs that fall into other categories. It is important to underline how the hierarchy of PCs is relative in that it occurs within each category (the critical points referring to risks of different types must not be compared with each other) similarly to what happens on the ground, e.g. for the various natural risks (hydrogeological, seismic, volcanic). In the Magic Project Critical Points have been defined as one or more morpho-bathymetric elements in correspondence with which, in the interpreter's judgement, a phenomenon capable of causing damage could be generated to surrounding coastal infrastructure and/or communities. The definition of PCs takes into account all types of data available (historical, seismic, modeling) and is also based on the specific knowledge of the interpreters in the various areas. All this implies that the identification of the PCs is extremely subjective and related to previous knowledge and data available to the interpreter. For a complete understanding of the product, read the reference methodological document.
