Nevado del Huila'(in English (IPA) /nv.do dl wi:.la/), at , is the highest volcano in Colombia, located in Huila Department. 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 habitants still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero.
On April 18, 2007, the volcano erupted twice causing avalanches into the Paez River; this event caused water levels to rise along the Magdalena River. More than 4,000 people were evacuated with no casualties reported.
2008 activity and eruption
Nevado del Huila became active again in March 2008. After a multitude of earthquakes inside the volcano, Colombian authorities declared a state of yellow alert on March 18. The state of alert was increased to orange on March 29, meaning an eruption could be expected within days or weeks. Hundreds of people were evacuated. On April 14, 2008 at 11:08 pm, an ash eruption took place, prompting the government to issue a red alert and evacuate 13,000 to 15,000 people from around the mountain. The state of red alert was again lowered to orange on April 16, following diminished activity.
November 2008 eruption
On November 20, 2008, the volcano erupted at 0245 GMT (at 2145 on November 20 local time) according to Colombian Institute of Geology and Mining. An immediate mass-scale evacuation was put in motion by the Colombian authorities, which the inhabitants of some towns reportedly refused. There were no injured reported at the time. On November 23, 2008, BBC News'', citing Colombian authorities, announced that the eruption had claimed ten lives, with 12,000 nearby residents being evacuated and emergency services unable to reach many of the more remote locations. The eruption had triggered an avalanche of earth and debris that damaged houses, bridges and crops on plantations. The three small towns of Paicol, La Plata and Belalcazar along the Paez River were affected by this eruption.
President Alvaro Uribe flew over the affected area after the volcano erupted. Extensive instrumentation of the volcano, put in place by the existing national system for prevention and care of disasters, which includes training of local inhabitants in high-risk regions and deployment of alarms in nearby towns, reportedly prevented large scale deaths. President Alvaro Uribe ordered the Air Force of Colombia to create an "air bridge" to provide supplies for cut off towns along the Paez River.
