Parossismo di nuovo SE Etna cratere 10-11 Nov 2013: attività stromboliana

Etna had one of her largest paroxysms in recent years during 10-11 November 2013 during which she produced intense lava fountains and rivers of lava. However, being a capricious Sicilian woman, she only let people see the very beginning and the end of it, and hid herself in a large snow storm during the main phase of the eruption.

Tom and Ingrid faced strong the winds and cold from a viewpoint on Valle del Bove in order to observe the (still spectacular) strombolian activity at the New SE crater that preceded and followed the main phase of the eruption, as well as a surprise: some of the most beautiful smoke rings ever (see separate gallery).

Strong southwesterly winds push almost all bombs to the eastern side of the New SE crater. 
After this picture (taken around midnight), the summit gradually becomes hidden in a massive cloud cover, as a snowstorm approaches that lasts until the next afternoon, while Etna increases her activity until the next morning, producing huge fountains and several large lava flows.

Il pomeriggio successivo (12 novembre), le piste superiori dell'Etna sono tutto bianche di neve. La fase principale del parossismo è finita, ma le esplosioni ogni minuto o così continuare presso il NSEC. È interessante notare che, molti di loro producono vapore anelli, spesso in una riga.

Some of the eruptions are from giant gas bubbles that explode at the top of the magma column inside the vent, sending huge liquid bombs in all directions. Shock waves can be seen exiting the crater. Seconds later, a loud detonation is heard that echoes several times in the Valle del Bove. (Photo: Tom Pfeiffer)
