Subject: Weekly Bulletin of volcanic activity of the volcano Nevado del Huila
The level of activity of the volcano continues at:
Amarillo activity level or (III): changes in the behavior of volcanic activity.
Analysis and evaluation of information obtained by the volcano monitoring network of Nevado del Huila, during the week between 15 and 21 June 2016, The SERVICIO Geologico COLOMBIANO–Observatorio Vulcanológico y Sismológico of Popayán informs that:
During the period, it was recorded a total of 103 seismic events, of which 49 were related to fracturing processes of the rock (type VT) and 54 with fluid dynamics in volcanic conduits. Of these, 51 were classified as long-period events (type LP), one (1) as hybrid and two (2) as pulses of low energy Volcanic Tremor (TR).
During the week, it was possible to obtain images of web cameras from Caloto, Tafxnú, Maravillas, La Palma and Verdun, in which a column of white steam was observed.
On June 21, a mobile flow measurement of SO2 was made, between the cities of Popayan (Cauca) and Mondomo (Cauca). The emission was calculated at 691t / day, with a dispersion to the northwest side of Nevado del Huila volcano.
Sensors for basic techniques of deformation , of magnetic fields and acoustic sensors, have registered no changes associated with volcanic activity.
Therefore, it is concluded that during the evaluation period, the volcano continued to show stable behavior.
The Colombian Geological Service continues to be alert and report timely to the changes that may occur.
