Finally, around 03 h in the morning on 12 May (local time = GMT+2), the fourth lava fountain of Etna in the year 2011 burst into the night sky. For many hours, there had been increasingly vigorous Strombolian activity and a small lava flow, and the amplitude of volcanic tremor was rising.
The fountain lasted for a couple of hours and ended at daybreak. The last stages of the paroxysm occurred in the most beautiful light and colors; by 06 h it wa essentially over.
This photo was taken from Monte Fontane, on the east- northeastern flank of Etna, with a Nikon L110
