Abstract

Active volcanic environments, such as Stromboli (Aeolian Islands, Italy), are often affected by secondary hazardous phenomena as wildfires triggered by explosive activity. Such secondary hazard are able to cause  damages in the surrounding human settlements, cultivation and  huge losses of vegetation. This study identifies and maps the burnt areas during the 2019 summer explosive activity. Between 2nd July and 5th September, two paroxysms, along with intense explosive activity, caused extensive wildfires, affecting vegetation and the inhabited Ginostra village. Landsat-8, Sentinel-2, and Pléiades satellite data have been processed to calculate the spectral indexes NDVI and NBR. Such index identified burnt areas making the difference of NDVI and NBR maps between pre- and post- paroxysm (3rd July). The 3 maps of burnt areas obtained by satellite data were compared with the burnt areas mapped  by using a very high spatial resolution drone imagery. Fire-outbreaks were also detected between 4th July and 5th September, due to the high explosive activity during such period and due to the second paroxysm occurred on 28th August. As Stromboli is a popular tourist destination, this study offers an useful tool for mitigating volcanic secondary hazards, such as wildfires.
