The volcano had been under increased vigilance since 3 Dec, when seismic activity started to pick up and suggest important internal changes.
It is impossible to say whether the new activity is or will become a magmatic eruption and how it will continue. For now, the Manizales observatory maintains alert level 3 (yellow) unchanged.

No major changes have occurred over the past week. The volcano produces intense degassing, with steam/gas plumes rising up to 2.5 km above the crater. Seismic activity has remained similar to past weeks at fluctuating low to medium levels. ... [more]

Over the past weeks, the volcano continued to have rather low seismic activity, mainly in the "usual" area S and SE of the Arenas crater at approx 8 km depth. At the surface, the volcano produces intense degassing with a plume sometimes reaching 1.5 km height. [more]

Volcanic activity at the surface (degassing) and inside (earthquakes) has remained comparably low. ... [more]

An earthquake swarm affected the volcano on 7 Oct, including a volcanic-tectonic quake of magnitude 2.7 at 3.2 km depth northeast of the Arenas crater. This could indicate that new magma has been rising into the shallow volcano's conduit, which might (or not) lead to new eruptive activity. [more]
