On February 4 around 12h , a modest but continuous ash emission was noticed in New crater southeast , and the issuance of a lava flow at the start of one of the vents at the easthern base of the cone NSEC . The flow traveled about 1,000 meters on the east wall of the Valle del Bove .
By early evening , the frequency of ash emission is 5-10 by hour separated by a passive vapor emissions. They are accompanied by incandescent material . These bursts stop around 19h GMT, while lava continues to flow.

February 6 , ash emissions continue at the first time . The eruptive activity is characterized by small strombolian explosions , expelling incandescent pyroclastic material at 50-100 m. above the edge of the crater , and lava emission from two vents at the base of NSEC . The lava flow is now ahead of a flat portion at the base of the east wall of the Valle del Bove, north of the Monte Centenari .
During these three days , the average amplitude of tremor remained at a low level, without major changes .

On 7 February, the Strombolian explosions succeed more quickly in the morning , with the emission of lava from the two mouths at the base of the cone.
A note : the average amplitude of tremor increased slightly since the beginning of the

To 20h , explosions succeed at a rate of 10-12 per minute, with glowing expulsions to a maximum of 150 meters above the crater rim and a few bombs falling on the flanks of the cone. The lava flow reached the altitude 2300.
On 8 February, in the afternoon , the tremor rises again, and the explosions of ash multiply ... Etna " is doing like a train" , with a succession of puffs.
