Tourists (including me) climb Bocca Nuova (one of Etna's summit craters) in July 1979, after being taken by all-terrain vehicles to a car park at the base of the cone.
Just two months later, on 12 September 1979, a sudden explosion happened in the Bocca Nuova. Lava blocks were ejected, killing 9 tourists and injuring 22. This tragedy put an abrupt end to the mass tourism that had been practised there until then.
