“…Measurements for calibration of these products are taken using GNSS and total station. After the change is identified using field verification, InSAR images are again used to verify and assess the extent of the damage to the cultural heritage site [22]. The methodology is presented in figure 2.…”

“…The network consists of a reference point and additional nodes, established at specific points of interest (i.e. points on peaks or ridges that may indicate/warn of a potential hazard) [20,22]. Network points are measured regularly using satellite (GNSS) and ground measurements (via high precision total stations and levels) to estimate the potential relative motion with respect to the network reference point, during the life-span of the monitoring activity.…”

“…The number of points is a function of site vulnerability parameters as indicated by geology specialists. The network nodes (or control points) need to be incorporated into the site and placed in such way as to ensure mutual visibility with the total station setup at the reference point [20,22].…”

Currently, assessing geo-hazards in cultural heritage sites takes place after the geo-hazard has occurred. The long-term vulnerability of cultural heritage is commonly focused on the site itself, in response to environmental risks, without fully considering or understanding the entire geological and geotechnical context. However, the high costs of maintenance of cultural heritage sites directly enforce the prioritisation of the monitoring and conservation policies to ensure sustainable conservation. Monitoring the deformation of structures as well as their surroundings facilitates the early recognition of potential risks and enables effective conservation planning. This paper will present the results of the case study of the UNESCO World Heritage Site of Choirokoitia, Cyprus, where long-term low-impact monitoring systems such as UAVs and geodetic techniques were used to monitor and assess the risk from natural hazards on the archaeological site to evaluate potential geo-hazards.

“…A complete analysis involves geotechnical, structural, and engineering issues and can lead to the design of adequate countermeasures (Fanti et al 2013). In literature, there are many examples of integrated approaches based on different survey and monitoring techniques for the study and conservation of cultural heritage sites affected by geohydrological hazards (Margottini and Spizzichino 2014;De Finis et al 2017;Themistocleous et al 2018). In particular, remote-sensing technologies are increasingly becoming useful tools for the onsite preservation of cultural heritage and are used to constantly update the condition report of a monument (Tapete et al 2013;Themistocleous et al 2015;Chen et al 2018).…”

On May 25, 2016, an artificial riverbank of the Arno River collapsed just upstream from the famous Ponte Vecchio bridge in the city of Florence, Italy, a UNESCO World Heritage Site. An analysis of the failure was performed to identify the damage condition of the involved structures, to define the causes of the failure, and preserve the site. This study was based on borehole integration and geotechnical characterization, terrestrial laser scanner (TLS) and digital photogrammetry (DP), bathymetric and geophysical surveys, riverbank stability analysis, and wall seismic vibrations assessment. The TLS survey results were used to characterize the three-dimensional (3D) wall deformations pattern, the landslide geometry, and to define the involved volumes. The riverbank stability analysis demonstrates that the lower safety factor was obtained in the case of complete saturation of filling materials and low river level in accordance with the major cause of collapse being attributed to the loss of water from subterranean pipes.

“…To reach a broad group of recipients, a comprehensive system needs to be built which will ensure the acquisition of data from satellites, their collection in a user-friendly database, and the possibility of rapid data processing that leads to beneficial decision making. 6 Primarily, the database should be accessible not only for public administration, including crisis management, but also for the scientific community, enterprises, and regular citizens. It is worth noting that citizens possess very diverse needs within recognized citizen advocacy associations or foundations, which must be taken into account; 7 these include concerns that directly impact mortality and morbidity outcomes at the local level.…”

Considering climate change, the risk of natural disasters requires a comprehensive approach on the part of all entities dealing with crisis management. Despite the advanced technologies available to predict weather phenomena, it is often unmanageable to take remedial measures, and the best solution is to suitably prepare for, and efficiently operate after, the occurrence of any given crisis. Nevertheless, it is imperative to implement the latest techniques and solutions which will allow for better preparation and responsiveness in the event of natural disasters. This manuscript presents results of initial analysis concerning the currently tested project, which is aimed at, among other things, improving safety in the event of natural disasters in Poland. There were two reasons for creating the manuscript. First, to present the potential of the system currently being built in Poland, which aims to reduce the risks associated with natural disasters and minimize the problems related to crisis management in Poland. And second, to open discussions and create grounds for information exchange between countries implementing similar solutions, especially neighboring countries, with which joint actions could be taken in the event of disasters in border areas.
