Subject: Weekly Bulletin activity of volcano Nevado del Huila.
The level of activity of the volcano continues to LEVEL YELLOW (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 11 and 17 November 2015, the Servicio Colombiano Geológico – Observatorio Vulcanológico y Sismológico de Popayán reports:
During the period evaluated, , including 104 were related to rock fracturing process (type VT) and 94 with fluid dynamics in volcanic conduits. Among these, 89 events were classified as long-period type (LP), three events associated with processes involving both fracture mechanisms such as fluid movements (HB type) and two pulses of volcanic tremors with a low energy level (TR).
The images taken by the webcam Caloto and La Palma, showed a degassing process of the volcanic system.
The sensors for monitoring soil deformation, acoustic sensors and magnetic field sensors recorded no changes associated with 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).
