JPEG file comment | Star Trails and Lava Plume on Mount Etna February 2021 Stack Nel pomeriggio del 16 febbraio l'Etna ha iniziato una fase eruttiva estremamente intensa. Per giorni i suoi crateri sommitali, tra cui soprattutto il nuovo cratere di sud-est, hanno mostrato un'importante attività eruttiva che si è manifestata principalmente con il rilascio di polvere e sporadiche esplosioni di carattere stromboliano accompagnate da fontane di lava. Verso le 17 una importantissima colonna di ceneri si è levata dal nuovo cratere di sud-est accompagnata da un altrettanto importante aumento della scossa vulcanica (vedi file allegato). Insieme alla nuvola, che nel frattempo si era estesa a tal punto da raggiungere la provincia di Siracusa, il cratere ha riversato un'estesa colata lavica che, in breve tempo, ha raggiunto la valle del Bove (bue) scorrendo sul suo piste. Le fontane di lava erano così alte e intense da essere visibili anche da lontano e alla luce del sole. Vedendo cosa stava succedendo, mi sono diretto verso il vulcano nella speranza di fotografare il cielo notturno e il flusso di lava. I primi scatti sono stati effettuati in località Piano Vetore e mostrano l'attività in corso presso il nuovo cratere di sud-est ripresa con un forte ingrandimento. Dietro la coltre di polvere è possibile vedere le stelle che, durante la mostra, hanno tracciato una scia di stelle. Successivamente mi sono spostato sul Monte Zoccolaro raggiungendo il limite della Valle del Bove. Da lì ho fotografato la colata lavica che, scorrendo, aveva disegnato una stella a 5 punte quasi a riflettere la bellezza del cielo stellato sulla terra. Durante gli scatti, una brillante meteora ha solcato il campo inquadrato per finire la sua corsa proprio sopra il cratere in eruzione (è possibile notare la variazione di colore dal verde al rosso). I paesaggi sono caratterizzati da strisce di lava nera (la sciara) mista a polvere nera e neve. La serata si è conclusa con altre due riprese. Il primo mostra la bellezza delle fontane di lava e delle rocce che si depositano sulla sommità del cratere. La lava insieme alle stelle hanno tracciato nel cielo tracce luminose in un caso di fuoco e nell'altro di luce stellare a testimoniare l'energia che pervade il cosmo! L'ultima inquadratura mostra invece un'altra meteora, non brillante come la prima, sopra il paesaggio vulcanico attraversato da una lingua di fuoco della colata lavica. During the afternoon of February 16th, Etna began an extremely intense eruptive phase. For days, its summit craters, including most of all the new south-east crater, showed an important eruptive activity that mainly manifested itself with the release of dust and sporadic explosions of a Strombolian character accompanied by lava fountains. At about 5 pm a very important column of ashes rose from the new south-east crater accompanied by an equally important increase in volcanic tremor (see the attached file). Together with the cloud, which in the meantime had extended to such an extent as to reach the province of Syracuse, the crater poured out an extensive lava flow which, in a short time, reached the valley of the Bove (ox) flowing on its slopes. The lava fountains were so tall and intense that they were visible even from a distance and in sunlight. Seeing what was happening, I headed for the volcano in hopes of photographing the night sky and the lava flow. The first shots were taken at the Piano Vetore locality and show the activity in progress at the new south-east crater taken with a strong magnification. Behind the blanket of dust it is possible to see the stars that, during the exhibition, have drawn a star trail. Later I moved to Monte Zoccolaro reaching the edge of the Bove Valley. From there I photographed the lava flow that, flowing, had drawn a 5-pointed star as if to reflect the beauty of the starry sky on earth. During the shots, a brilliant meteor plowed through the framed field to finish its run right above the erupting crater (it is possible to notice the color variation from green to red). The landscapes is characterized by stripes of black lava (the sciara) mixed with black dust and snow. The evening ended with two more takes. The first shows the beauty of the lava fountains and the rocks that settle on the top of the crater. The lava together with the stars have drawn luminous traces in the sky in one case of fire and in the other case of starlight to bear witness to the energy that pervades the cosmos! The last shot instead shows another meteor, not as bright as the first, above the volcanic landscape crossed by a tongue of fire of the lava flow. https://www.instagram.com/dariogiannobile/ FB: @dariogiannobile Canon 6d, Canon 70-200mm, f/2.8, Iso 640, 30 sec, 8 shots |
