Aerial Views Of Volcano Mount Etna

CATANIA, ITALY - OCTOBER 11: The summit craters of Etna volcano seen from the helicopter of the Italian Coast Guard. The helicopter flew over to over 4000 meters of height to give chance to volcanologists of INGV (National Institute of Geophysics and Volcanology) of Catania to monitor from above the craters and do the reliefs on magma rising with thermal cameras. The volcano in recent weeks has given signs of activity with rumbles, explosions and seismic activity in increase, signals of a likely imminent eruptive activity, on October 11, 2018 in Catania, Italy.
