Eruptive activity has started at the volcano in the form of abundant ash emissions from the volcano's summit crater since yesterday.
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.

SO2 plume from Nevado del Ruiz volcano (NOAA)
Monday, Jan 13, 2014
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]

Seismic signal from Nevado del Ruiz today (OLL station, INGEOMINAS)
Monday, Oct 07, 2013
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]
