Residents have been urged to abandon their homes in a scattering of towns in the western departments of Cauca and Huila as officials put a yellow alert in effect in expectation of the eruption of Volcano Nevado del Huila.
As many as 108 seismic events are occuring daily, up from between 80 and 89 in the last week of August, Adriana Agudelo Restrepo, technical coordinator of the Colombian Institute of Geology and Minerology in Popayán, told El Pais.
In the last eight days, 761 seismic events have been registered, including 197 relating to fluid dynamics inside volcanoes, and the most powerful have registered up to 4.6 on the Ritcher scale. If this level of activity continues, the alert level will rise to orange, reported El Pais.
April of last year, the alert in the area rose to red and inhabitants of the municipality of Paéz-Belalcázar, Cauca, had to evacuate in the middle of the night.
In 1994, more than 1,000 people were killed when an avalanche provoked an eruption of Volcano Nevado del Huila.
