Etna volcano (Italy): 17th paroxysm of New SE crater on 23 OctSunday Oct 23, 2011 22:31 PM |
Another paroxysmal eruption (the 17th in 2011) is in progress at Etna's New SE crater at the time of writing. The volcanic tremor recorded by INGV has risen sharply to 50 times above background levels, and strong strombolian activity and/or lava fountains, as well as a lava flow into the Valle del Bove are visible from various webcams. This eruption comes more than 15 days after the previous one on 8 Oct, which marks the longest so far interval between paroxysms, and might be a sign of exhaustion of the magma reservoir and the dynamics feeding this exceptional serious of eruptions.

 The lava fountains from the lower part of the SE fissure at the beginning of the 16th paroxysm of Etna's New SE crater, ca. 15h30, 8 Oct 2011 Tom Pfeiffer and his group of VolcanoDiscovery's Stromboli to Etna tour were lucky to be able to witness the eruption from close range. The activity started a slow gradual increase of volcanic tremor visible since around 9am, and with increasing and noisy strombolian explosions from one and later several vents inside the crater fissure of the New SE cone at around 1h00 pm; a lava flow emerged from the narrow SE directed channel aroud 3 pm, accompanied by a row of low liquid lava fountains just outside the gap of the crater, aligned on the SE trending fissure dividing it. Heavy fog, hail, very cold temperatures and strong winds prohibited detailed observations of the main phase of the eruption between ca. 3 and 4 pm, when taller lava fountains could be heard. A dense column of ash was sometimes seen rising above the clouds and drifting east. The eruption was over by around 5pm, by which time, the summit area again cleared. By then, the lava flow had descended the steep wall of the Valle del Bove and reached its base.

The 14th paroxysm of Etna's New SE crater is in progress at the time of writing. Bad weather conditions hide the eruption, but the seismic signals of INGV Catania show that a major eruptive episode is occurring. Since 9am, volcanic tremor has been gradually increasing to (at the moment) 30+ times background levels, and is still rising. Most likely, lava fountains are being ejected from vents inside the crater and lava flows descending into Valle del Bove if the new episode is similar to the previous ones. ...

The 13th paroxysm from Etna's New SE crater occurred this morning between ca. 8 and 10am, following a steep increase in tremor and a short period of rapidply increasing strombolian activity from several vents inside the new crater. The eruption intensified into lava fountains generating a tall ash plume drifting SSE and showering a narrow sector south of Etna with ash. ...

Another powerful eruption with an intense peak activity of tall lava fountains - a so-called paroxysm - occurred at Etna volcano's New SE crater earlier today. This marks the 12th event of the series in 2011 so far. The main phase of the eruption lasted between around 5 and 7 am local time. ...

The 11st paroxysm of Etna's New SE crater is taking place. Strombolian activity and increased degassing started late during the night and early morning. The activity increased into lava fountains producing a tall ash column probably between 8 and 9 am. A lava flow is emitted that descends into the Valle del Bove.
