Privileged documentary observations of surveying of “fragile heritage” in emergency conditions: the case studies of Pomarico landslide and of Montescaglioso abbey

In the survey activities that supervise the knowledge paths necessary for the acquisition of useful data for the subsequent intervention phases, we often come across emergency conditions, where the timeliness of operations is essential for the protection of the assets on which we are working. Where there is a degenerative process that evolves in slow or rapid times, it becomes essential to "photograph" and monitor the situation until the definition of the interventions that will be carried out to remedy the problem. The unpredictability of the possible evolution of events that cause emergency conditions requires rapid actions both in the detection phase and in the subsequent phases of problem analysis and definition of interventions. This contribution intends to document two experiences carried out on "fragile heritage", which in-volved the research group of the University of Basilicata, in support of local institutions to carry out surveys in the field in "extraordinary conditions".
