SO2 plume from Nevado del Ruiz on 29 Dec
An SO2 plume drifting from the volcano shows ongoing intense degassing. INGEOMINAS reported occasional steam and ash venting. Small earthquakes and occasional low-level volcanic tremor pulses can be seen on the seismic recordings.

Seismic recording on 18 Dec on OLL station (INGEOMINAS)
An episode of small pulsating volcanic earthquakes occurred today.
Mon, 17 Dec 2012, 19:11
Low-energy seismic activity associated mainly with rock fracturing within the volcanic edifice continued, located primarily in the northeastern and southeastern areas below Arenas crater, at depths ranging between 1.5 and 6 km. The maximum magnitude recorded was 1.2 on the Richter scale. ...more [read all]

SO2 plume from Ruiz on 19 Nov 2012 (NOAA)
A significant SO2 plume is visible on the current NOAA satellite image and seismic activity shows an increased number of small quakes and long-period events.

A small eruption might have occurred at Nevado del Ruiz prior to 14:47 GMT yesterday 15 Nov. As a precaution for aviation, Washington VAAC issued an alert of possible ash in the atmosphere. The report itself was based on the detection of a small hot spot on satellite imagery and seismic data. No ash could be identified on satellite images due to cloud cover and darkness, and the local volcano observatory has not (yet) confirmed any new eruption.
Thu, 15 Nov 2012, 07:40
During the past week, Nevado del Ruiz showed in increase in seismic activity with more frequent small quakes. They were mostly located N and NW of the Arenas crater at depths between 4 and 10 km. The largest was a magnitude 2.2 event on 5 Nov at 01:38 local time.

Seismic recording from 00-06 am GMT today on OLL station (INGEOMINAS)
Seismic activity has remained generally calm with the exception of a small regional quake earlier today and an elevated number of small earthquakes visible on today's seismic recordings.
Sat, 10 Nov 2012, 08:36
Seismic activity has calmed down considerably, but few weak quakes and emission signals remain visible.
