The accelerated growth of unmanned aerial vehicles, also known as drones, and their application in various fields of action present an opportunity for their use in emergency management during a disaster. The various technologies that unmanned aerial vehicles can incorporate provide them with applications that can be very useful in disaster management, for example, they can analyze in detail (via mapping) the affected region, assist in building a network of communication between the survivors of the catastrophe and the nearest rescue teams and mobile networks, and collect all types of information and data that can be immediately transmitted to the emergency management center for decision making. Therefore, this review analyzes the potential functionalities and benefits of unmanned aerial vehicles, as technological support in emergency management, considering both the typology of disaster and its performance in the different phases of disaster development and its management.
