lava flows from the 15th paroxysm of the New SE crater of Etna volcano (webcam image from http://www.radiostudio7.it/webcam.asp)The 15th paroxysm of Etna's New SE crater occurred in the evening of 28 Sep, a few days earlier than what statistically had been expected (based on thze steady increasing intervals between the past similar events).
Bad visibility due to clouds and rain prevented detailed observations, but the activity started slowly during the afternoon, with exponentially rising levels of volcanic tremor, ash emissions and increasing strombolian activity originating from probably several vents inside the new crater.
The eruption culminated in a brief (1 hour approx) phase of lava fountaining around 9-10 pm, and produced large lava flows towards the E and ESE into the Valle del Bove. The eruption was over at around 11pm, after a peak between around 9-10pm. This marks #15 in the series of powerful eruptions of the New SE crater in 2011, and followed the previous one on 19 SSep after an interval of 9 days.
