Lately, the scientific community is then giving greater attention to the monitoring of these infrastructures and their close surroundings to predict and to survey potential damage and consequences, particularly structural ones, in case of natural hazard. A quick rising method to conduct such studies is based on fixed wings unmanned aerial vehicles (FW-UAV) because of their quick deployment and speed in collecting high quality data, their range of operativity, the guaranteed safety for operators and the wide range of sensors they can carry on. A very interesting feature is that, when a pre-event survey is available, FW-UAV can be used to accurately estimate seismic and earthquake- induced landslides’ structural vulnerability through data driven models and artificial intelligence creating 3D interactive maps in a relatively short time. These models, taken on a regular basis, are also very useful to support infrastructural maintenance, emergency operations and their strategical planning. Despite its potential, this technology is still not widespread and few examples are available in a country with a complicated orography and seismic vulnerability such as Italy, so this study aims to organically summarize existing literature to explore all possible future developments and give a possible methodology with a hands-on case study concerning a transportation infrastructure to point out the significant opportunities to improve prevention, response and resilience given by FW-UAV.
