Etna volcano: paroxysm of SE crater on 9 July 2011

The large pit crater at the SE base of the SE crater has been the site of the last eruptions of Etna volcano, including several violent paroxyms (4 in 2011 until May). It has almost grown itself to a new crater, sometimes now called "New SE crater". (Photo: Tom Pfeiffer)

At around 13h00, a lava flow starts to emerge slowly from the gap (the "gate") of the pit crater. We now are almost certain that the eruption is headed towards a paroxysm. (Photo: Tom Pfeiffer)

Jetting fountains start and a column of dark tephra (ash, lapilli and bombs) starts rising. On the other side not visible from here, a lava flow increased dramatically its output down into the Valle del Bove. (Photo: Tom Pfeiffer)
