Nevado del Huila , at 5,365 metres (17,602 ft), is the highest volcano in Colombia.
After being dormant for more than 500 years, the volcano showed heavy signs of activity in 2007 and 2008.
As of February 20, 2007, there were more than 7000 "minor" seismic events, and a high state of alert was
in place for the departments of Cauca, Huila, Caldas and Valle del Cauca.
The volcano erupted twice in April 2007, once in April 2008 and again in November 2008.
Any eruption would affect the small villages around the volcano, mostly Paez, Cauca, where their inhabitants
still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero.
