The Tungurahua Volcano Erupts
The Tungurahua Volcano erupts as seen from the town of Juive Grande, Ecuador, on November 28, 2011. Authorities in Ecuador upgraded a possible eruption warning from yellow to orange, as the activity of the volcano raised suddenly.
Tungurahua (5,023 m) is located in the Cordillera Oriental of the Andes of central Ecuador, 140 kilometres (87 mi) south of the capital Quito. Nearby notable mountains are Chimborazo (6,267 m) and El Altar (5,319 m). It rises above the small thermal springs town of Baños de Agua Santa (1,800 m) which is located at its foot 8 km to the north. Other nearby towns are Ambato (30 km to the northwest) and Riobamba (30 km to the southwest). Tungurahua is part of the Sangay National Park.
Recent volcanic activity
In 1999, after a long period of quiescence, the volcano entered an eruptive phase that continues to this day (as of December 2011).
The renewed activity in October 1999 produced major ashfall and led to the temporary evacuation of more than 25,000 inhabitants from Baños and the surrounding area (El Comercio 1999). Activity continued at a medium level until May 2006, when activity increased dramatically, culminating in violent eruptions on 14 July 2006 and 16 August 2006. The 16 August 2006 eruption has been the most violent since activity commenced in 1999. This eruption was accompanied by a 10 km high ash plume which spread over an area of 740 by 180 km (IG-EPN 2006, [4]), depositing ash and tephra to the southwest of the volcano. Several pyroclastic flows were generated that killed seven people, and destroyed a number of hamlets and roads on the eastern and northwestern slopes of the volcano (El Comercio 2006). The seven people who died were a family of five and two scientists.
A further eruption and evacuation occurred on 4 December 2010. Ecuador's National Agency of Risk Control issued a "red alert", later downgraded to orange. The Ecuadorean Institute for Geophysics reported a rapid increase in seismic activity, a number of explosions and an ash cloud reaching 2 kilometres (1.2 mi) in height. Article source: wikipedia
