Nevado De Huila , Colombie : 318 seismic events were recorded .

Subject: A weekly activity of the volcano Nevado del Huila
The level of activity of the volcano continues: LEVEL YELLOW (III): behavioral changes in volcanic activity.

Analysis and evaluation of information obtained by the monitoring network volcano Nevado del Huila, during the week between 13 and 19 January 2016.

The Colombian Geological Service – Volcanological and Seismological Observatory of Popayán reports:
During the period evaluated, 318 seismic events were recorded, of which 141 were related to rock fracturing process (type VT), and 177 to the fluid dynamics inside the volcanic conduits. Of these, 161 were classified as long term events (LP), five (5) as hybrid events which have been associated with both the fracturing mechanisms and a fluid transit (type HB) and 11 volcanic tremor pulses of low amplitude (TR).

During the week, it was possible to obtain images from webcams from Tafxnú, Maravillas, Caloto and La Palma, in which the volcanic system degassing process were evident, showing a white steam column.
The technical sensors for monitoring ground deformation, acoustic sensors and magnetic field sensors recording the variations associated with volcanic activity did not record changes.

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 monitor and report on appropriate changes that may occur.
