Picogeo researchers have analysed Etna’s most powerful eruption in 2021
Picogeo researchers publish a paper on the Etna Eruption of the 12th of March 2021
“Anatomy of a Paroxysmal Lava Fountain at Etna Volcano: The Case of the 12 March 2021 Episode” is a paper by Picogeo researchers S. Calvari, A. Bonaccorso and G. Ganci dedicated to their work on the Etna Eruption of March 2021. Thanks to a combined data from the ground, satellites and a high precision borehole stainmeter, researchers were able to analyse the Etna’s largest eruptive episode in 2021 so far. Here is a passage from the Abstract of the article that we encourage you to read fully here
On 13 December 2020, Etna volcano entered a new eruptive phase, giving rise to a number of paroxysmal episodes involving increased Strombolian activity from the summit craters, lava fountains feeding several-km high eruptive columns and ash plumes, as well as lava flows. As of 2 August 2021, 57 such episodes have occurred in 2021, all of them from the New Southeast Crater (NSEC). Each paroxysmal episode lasted a few hours and was sometimes preceded (but more often followed) by lava flow output from the crater rim lasting a few hours. In this paper, the researchers use remote sensing data from the ground and satellite, integrated with ground deformation data recorded by a high precision borehole strainmeter to characterize the 12 March 2021 eruptive episode, which was one of the most powerful (and best recorded) among that occurred since 13 December 2020.
