Etna volcano update: Paroxysm from New SE crater ?
Sunday Jun 15, 2014 15:52 PM | BY: T
Eruption at Etna's New SE crater
A violent phase of explosive / effusive activity began over night. Strombolian activity at the New SE crater and volcanic tremor started to increase last evening. This increase continued throughout the night and this morning,- great luck for those on our current tour to Stromboli - Vulcano and Etna.
Current tremor amplitude (ESLN station, INGV Catania)
At the moment, tremor is stagnating, and it is not clear whether the current eruptive phase will culminate in a true paroxysm (lava fountaining).
Near-continuous explosions from the several vents at the summit of the NSEC occur in rapid succession and eject glowing spatter to heights of 100-200 m during in what could be described as pulsating lava fountains. A vent at the eastern part of the summit occasionally ejects dark jets of ash. Brown ash plumes rise from time to time from the northeastern rim of the crater, presumably from collapse events.
Unfortunately, heavy cloud cover, and thunderstorms around noon/early afternoon that deposited approx. 10 cm of fresh hail prevented detailed observations during most of the afternoon.
Starting from early this morning, several lava flows were effused that descended from the summit through the valley on the SE side of the crater and headed slowly towards the Valle del Bove rim.

No particular changes have occurred recently. Very sporadic and weak strombolian explosions continue at the summit vent of the New SE crater. Bocca Nuova also continues to produce sporadic ash emissions. [more]
