Ecuador's Tungurahua volcano shot columns of ash miles into the air on Wednesday, as officials ordered the evacuation of 3,000 villagers living near its slopes.
Some 1,000 villagers from the western flanks of the 16,575-foot volcano fled their homes for shelters at dawn, said Roberto Rodriguez, director of Civil Defence. He said 11 families who refused to leave, fearing looters, were removed by force.

The Tungurahua Volcano, which gives name to the province of Tungurahua in central Ecuador, restarted eruptive activity and is in an ongoing period of high activity, with 30 eruptions an hour, National Geophysics Institute (IGN) reported.
The situation of the steep-sided colossus, with an almost perfect cone reaching 16,500 feet in the Eastern Cordillera of the Andes, is similar to that of July 2006, when huge explosions with potential structural collapse amounted to 30 a day and the ashes, smoke and lava were almost two miles high.

Ecuador's Tungurahua volcano spewed molten rock, ash and gases and a local mayor reported 60 people missing, as authorities on Thursday evacuated hundreds of families from the threatened area.

Tungurahua had earlier shown a sharp increase in activity in July, when hundreds of villagers living near the volcano to flee their homes.
During the early hours of Thursday residents of the tourist city of Banos, with a population of around 17,000 people, briefly left their homes. Most have already returned to the town on the south side of the volcano's crater.
Local television stations showed images of molten rock blasting from the crater and massive clouds of ash spewed by the volcano.
Flows of molten rock, ash and gas blocked several roads near the volcano.

According to the Instituto Geofísico, on 1 August a pyroclastic flow from Tungurahua travelled an unstated distance Westward and left deposits 50 m thick consisting largely of blocks and ash. On 2 August, a small lahar travelled NW caused the closing of a highway. Strombolian activity was observed at night on 3 August. Small explosions were registered during 3-7 August. On 6 August, light ash fall was reported ~8 km SW in the town of Manzano.

RESUMEN DE LA ACTIVIDAD DEL VOLCÁN
Durante el día de hoy se observó un leve aumento en la actividad sísmica, especialmente en el número de eventos de largo periodo (movimiento de fluidos al interior del volcán). El número de explosiones se redujo un poco. La actividad superficial del volcán se caracterizó por la emisión de gases con un contenido muy bajo a moderado de ceniza, algunas fuentes de lava y la expulsión de bloques que rodaron unas centenas de metros bajo la cumbre del volcán.

The Terra satellite took this picture on July 17, 2006.
The image show Tungurahua and its neighbour, Chimborazo. A gray-brown plume of volcanic ash and/or steam emanates from Tungurahua, mingling with nearby white clouds. The volcanic plume appears to spread out in all directions near the summit then generally blow westward toward Chimborazo.

Tungurahua Volcano was ejecting gas and ash for the fourth consecutive day. This burst of activity proved to be the volcano’s most powerful since 1999. Besides volcanic ash and gas, the volcano produced molten rock that set fire to local vegetation. By July 18, the volcano’s activity had blocked roads, ruined bridges, covered nearby villages in ash, killed livestock, and prompted evacuations.

The Ecuadorian President's Office said on Tuesday that the Tungurahua Volcano, currently erupting in central Ecuador, had destroyed 19,000 hectares of farmland.
Tungurahua had destroyed 12,000 hectares in Chimborazo and 7,000 in Tungurahua, the Foreign Ministry said.
The 5,029-meter-high volcano, which is showering the region with ash and burning hot lava, entered a critical phase on Friday that might last for months or years.
It has devastated villages that have maize, potato, cereal and livestock farms and affected more than 13,000 people.
The Ecuadorian government has evacuated around 1,000 families from Bilbao and Cusua, two of the badly-affected areas and is preparing to evacuate residents from Chacauca, Juive and Ponton.
Ecuador's President Alfredo Palacio has ordered the cabinet to come up with an emergency plan. The government decided on Monday to spend 4.9 million U.S. dollars to tackle the disaster, and has already spent 300,000 dollars delivering food, medicine and drinking water to refugees.
