Nevado del Huila, cu 5 365 metri, este cel mai înalt vulcan din Columbia,[1] Stratovulcanul, care este situat în departamentul Huila, a fost acoperit de cantităţi de zăpadă din ce în ce mai reduse, de-a lungul ultimelor decenii. După o perioadă de circa 500 ani, în care vulcanul a dormitat, în 2007 a început să manifeste semne de activitate.
As of February 20, 2007, there were more than 7000 "minor" seismic events, and a high state of alert is currently in place for the departments of Cauca, Huila, Caldas and Valle del Cauca.[2] An eruption could result in a tragedy for 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.

[modifică] Erupţie din 2007
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. Some 4,000 people were evacuated with no casualties reported.[3][4]
[modifică] Activitatea şi erupţia din 2008
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.[5] 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.[6] 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.[7] The state of red alert was again lowered to orange on April 16, following diminished activity.[8]
[modifică] Erupţia din noiembrie 2008
On November 21, 2008, the volcano erupted at 0245 GMT (at 2145 on November 20 local time) according to Colombian Institute of Geology and Mining.[9] An immediate mass-scale evacuation was put in motion by the Colombian authorities, which the inhabitants of some towns reportedly refused. There were no wounded reported at the time. [10] 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. [11] The eruption had triggered an avalanche of earth and debris that damaged houses, bridges and crops on plantations.[12] The three small towns of Paicol, La Plata and Belalcázar along the Paez River were affected by this eruption.[13]
President Álvaro 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,[14] which includes training of local inhabitants in high-risk regions and deployment of alarms in nearby towns, reportedly prevented large scale deaths.[9] President Álvaro Uribe ordered the Air Force of Colombia to create an "air bridge" to provide supplies for cut off towns along the Paez River.[15]
