The volcano's New SE crater has become more and more active over the past few days, and started to show weak strombolian activity of varying intensity since yesterday morning. This activity produces occasional ash emissions which are rapidly dispersed in the summit area.

Over the past days, volcanic tremor amplitude has been showing continuous oscillations, with an overall gradually increasing trend, reaching high values during the past 24 hours. According to the volcano observatory, the source of the tremor - corresponding to the area of magma movement - is located under the SE Crater area at an elevation of 2800-2900 m above sea level, or 300-400 m below the crater rims.
No significant variations of ground deformation have been observed.
Although it has not (yet) produced another paroxysm since the last one past Friday, it might be heading towards one, or otherwise maybe shift towards a longer phase of moderate, persistent activity.
