News from Nevado del Huila volcano:
Wed, 22 Jan 2014, 09:25
A small increase in volcanic-tectonic earthquakes was noted by INGEOMINAS' volcano observatory in Popayán. A total of 138 seismic events were recorded over the past week, out of 112 were volcanic-tectonic quakes and the remaining 26 events related to fluid movements inside the conduits (long-period quakes and one tremor pulse). ...more

Following a nearby magnitude 4.5 earthquake at 06:07 local time on 9 Jan, a swarm of volcanic-tectonic quakes was detected at 12-16 km distance NE of the volcano and at approx 10 km depth. During the first day, more than 600 small quakes were recorded. The swarm decreased over the past days and no other (visual, deformation etc.) changes at the volcano were observed.

No significant changes in the volcano's activity of degassing and small earthquakes have occurred during the past months. INGEOMINAS' alert level remains yellow.
Thu, 16 May 2013, 08:57
The large volcano has remained calm with little variations in activity (degassing, 100-150 small earthquakes / week).
Thu, 31 Jan 2013, 06:56
Activity during the past week has not changed, characterized by degassing accompanied by normal levels of seismic activity (124 events of low energy).

Steaming and weak seismic unrest continue with little changes. During the past week, a total of 56 seismic events were recorded, including 22 volcanic quakes of rock fracturing and 34 reflecting fluid movements.

A total of 87 seismic events were registered during the past 7 days. 27 of these were related to rock fracturing and 60 with the fluid dynamics within volcanic conduits. Of these, 52 were classified as long-period events, 7 events such as hybrid and a pulse energy of low-level tremor.

A total of 110 seismic events were recorded. 33 were related to rock fracturing and 77 with fluid dynamics in volcanic conduits. Of these, 65 were long-period events, seven (7) hybrid and five (5) tremor pulses of low energy level.
