We carry out checks and real-time monitoring of natural and anthropogenic phenomena such as earthquakes and structural failures, through the measurement of physical-mechanical parameters it is possible to describe the interaction between the environment and the state variables of the structure intends to study. When the crack pattern of a structure (eg cracks on masonry, cracks, foundation collapses or structural collapses) is evolving, it is necessary to prepare a specific structural monitoring with deformometric measurements of active movements and rotations to delineate the origin, the entity and the evolutionary laws of the phenomenon, in order to define the type of intervention and to check the results.
