    Etna Volcano at Night

       Stelle e fuoco sull'Etna (1)   
      
      Photographer:  Teresa Molinaro   
      Summary Author:  Teresa Molinaro   
      
      Shown above is the glowing skyscape I observed as  Mt Etna (Sicily,   
      Italy) was erupting on a starry night earlier this year. This   
       stratovolcano is the most active in Europe. In fact, it's erupted   
      so often the past two years that  new volcanic material has added to   
      its height by approximately 100 ft (30 m). A larger eruption had   
      occurred several days before ( late May 2022), but when I arrived   
      weak explosive activity was still in progress -- emission of volcanic   
      sand from Etna's South-East crater. I was on the opposite side of the   
      mountain at the time and was intent on capturing both the starry sky   
      and  Montebello's lingering flames. Photo taken on June 2, 2022, at   
      10:00 p.m. local time.   
      
      Photo details: Nikon D7500 camera; F/3.5; 30 second exposure; ISO 800;   
      18 mm Nikkor lens.
