The volcano seems to have stabilized and this activity, termed as " persistent ", results in a low NSEC strombolian activity and lava flows out of a mouth located at the lower base of the cone inside the scar of the landslide occurred Feb. 11, 2014 . This landslide caused a dangerous pyroclastic flow ... which justified a ban on entering the valley.

Feeding cast remains variable and remain confined to the western part of the Valle del Bove, without creating problems . These days, the flow were expanded in the upper part of the west wall in overlapping .

Regarding the instability of the western slope of the new cone southeast , it has been recently observed some small rusty ash emissions  and a small thermal anomaly related to minor accidents in the area of ​​the effusive mouth.

The average amplitude of the volcanic tremor showed no significant changes , but the observations are disrupted by cloud cover.
