During recent weeks, the volcano has shown a significant increase in earthquakes associated with rock fracturing and the movement of fluids inside the volcano, located at depths between zero and four kilometers in relation to the surface.
Likewise, the data telemetry systems collected by the surveillance network show that the volcano building continues to gradually deform and that there is a small magmatic body, located 2 kilometers deep, which is migrating to the surface.
“With the current level of activity of the Puracé, the country must be prepared and take the necessary preventive actions,” said the director of the Geothreats technical area of the SGC, John Makario Londoño.
The Puracé volcano is located 27 kilometers from Popayán, the departmental capital of Cauca, and mainly indigenous and peasant communities live in its area of influence.
