Nevado Del Huila , Colombia : 359 seismic events were recorded.

Subject: Weekly Bulletin of activity of the volcano Nevado del Huila.
The level of activity of the volcano continues:
YELLOW activity level or (III): Changes in the behavior of volcanic activity.

Analysis and evaluation of information obtained by the monitoring network of volcano Nevado del Huila, during the week between 20 and 26 January 2016.
The Colombian Geological Service – Observatorio Vulcanológico and Sismológico of Popayan reports:

During the period evaluated, 359 seismic events were recorded, of which 181 were related to rock fracturing process (VT type), and 170 with fluid dynamics in volcanic conduits. Of these, 142 events were classified as seismic events of long period (type LP), twenty-one (21) as hybrid events that have been linked to both failure mechanisms and transit of fluids (type HB) and 7 impulses of volcanic Tremor of low magnitude (TR).
During the week, it was possible to obtain images from webcams Tafxnú, Maravillas, Caloto and La Palma, in which the volcanic system degassing process were evident, showing a white steam column.

The technical sensors for the surveillance of soil deformation, acoustic sensors and variations of magnetic fields associated have not registered changes caused by volcanic activity.
Therefore, it is concluded that during the evaluation period, the volcano continued to show stable behavior. The level of activity of the Nevado del Huila volcano continues to LEVEL YELLOW (III).
The Colombian Geological Service continues to be attentive and report on the changes that can occur in a timely manner.
