The strombolian and effusive activity marking the NSEC of Etna stopped on December 8 in the morning. Boris Behncke noted that on December 7th in the afternoon and evening, the new southeast crater had two different active eruptive vents , one on the eastern flank of the cone, the other in the eastern part of the NSEC only sporadically active.

The main lava flow spread over approximately 4 km, and stopped near the cone Monte Centenari.
