The next period of the revitalization of the volcano Tungurahua, located in the Central Andes, south of the capital of Ecuador, which began last Wednesday, affect the direction of air traffic in the country. A column of ash ejected from the crater of the volcano, is 12 km in altitude, and it forced the Civil Aviation Administration re-route departing from the capital to the south of the country. Aircraft on the route Quito-Cuenca, to deviate from a straight line to the coast or in the direction of the Amazon. In addition, as reported by the Secretary Emergency Maria del Pilar Cornejo, all air terminals are working in normal mode, none of the flights so far has not been canceled or postponed.
As the head of the National Geophysical Institute Hugo Yépez, currently registered ejection of ash and rocks from the entire surface of the crater, and the amount involved is of volcanic material as nothing compared with what remains inside the colossus. He told a press conference that, given this fact, this activity may persist for weeks. Volcanologists not preclude the new powerful eruption, bigger than the one that was registered in 2006. Marked expansion of the volcanic cone, which proves that the movement of magma to the hot surface. Another important point that distinguishes the current activity — increased emitted volcanic gases containing large amounts of ash, and more than a thousand tons a day. According Yépez, the situation is similar to that observed in August 2001, when the slopes of Tungurahua and the surrounding area has dropped so much ash that broke beneath the trees. Do not rule out active emissions pyroclastic jets.
Progressively increasing the current active Tungurahua registered from 20 April 2011. Publ.21.04 "Volcano Tungurahua like about yourself." The ash cloud is moving to the west and north-west. Authorities decided to cancel at least two days school work in settlements close to the volcano, where the situation is declared high-risk, which means a voluntary evacuation and the use of public funds for this purpose. Already evacuated 240 families housed in temporary shelters. A large number of ejected from the crater of the colossus of ash damaging plantations and pastures that troublesome residents Mocha, Tisaleo, Cevallos and Ambato (province of Tungurahua), Guano, Penipe and Riobamba (province of Chimborazo).
Volcano periodically revived in 1999, periods of activity followed by periods of relative calm, and in July and August 2006, Mama Tungurahua eruption left four dead, two missing and thousands of residents were evacuated, not to mention the damage caused by the death of livestock and plantations in several mountain provinces of Ecuador.
