Description

The Tungurahua name comes from two kichwa words "tungur" (throat) and "rauray" (burning). It is a stratovolcano whose almost perfect cone rises from the city of Baños at 1820m to the elevation of its maximum summit at 5020m. This 3200 meters probably makes it the most prominent volcanic cone in Ecuador. Its base diameter is about 7.5 km and the crater 550 meters, its average slope about 35 degrees. It has two main peaks covered most of the year with ice and snowfields. It remained practically closed to tourism since 1999, year in which its current eruptive period began. Since mid-2017 its activity has declined and the authorities has once again allowed access to its summit.

Eastern Cordillera; 8.6 kilometers in a straight line southwest of Baños, Tungurahua province.

When arriving at Baños, on the right side (south) there is a paved and well signposted road that goes up to the Pondoa little town. The entrance guard to the Sangay National Park is a little further up from Pondoa, where the trek to the Tungurahua refuge begins.

Recommendations

  • Normally the city of Quito, Baños, Ambato or Riobamba is taken as a starting point.
  • It is usually required two days to climb to the summit of Tungurahua.
  • It is possible to rent pickup trucks - taxis in Baños which can take you to the Sangay National Park entrance control.
  • Admission to the park is free but you will have to fill out a responsability release form if you plan to go to the summit.
  • The ascent to the refuge has a difference of more than one thousand meters, in the middle of a warm climate and a semitropical vegetation. If you load your big backpack get ready for a hard walking and generous sweat.
  • In the rainy seasons, it is very advisable to hike this path using rubber boots.
  • You will follow a long tunnel of branches and "bamboo" practically until you reach the refuge.
  • The refuge is small and at certain times you will have to sleep even under the tables.
  • Dogs sleep outside and are not welcome in the refuge.
  • The price is US. 10.00 per person with the right to use the kitchen (which may be excessively occupied).
  • Always use the latrine and not the cozy branches around the shelter.

Volcanology

Hall et al. (1999) divide this volcano into three successive buildings, Tungurahua I, II and III, the third being the current building. The two previous buildings suffered sectoral collapses 30 and 3 thousand years ago, whose avalanche deposits crop up in the valleys of the Chambo and Patate rivers. The activity of Tungurahua III would have begun with the emission of the great lava flow of the Juntas approximately 2300 years ago (Hall et al., 1999). Since 1300 AD the Tungurahua has produced eruptions with pyroclastic flows, ash falls, lava flows and lahars, at least once per century (LePennec et al., 2008).
The current eruptive period began in 1999 and persists until now. At the beginning, the current eruption was subcontinuous, characterized by Strombolian and Vulcanian explosions; and gas and ash emissions. In July and August of 2006, for the first time in this period the volcano produced two large explosive eruptions with formation of pyroclastic flows that affected mainly the western flank and the south western flank. The fall of ash associated with these events was of a regional nature, affecting even the city of Guayaquil. Since then the volcano has maintained intermittent episodes of activity with durations from a few days to weeks and activity breaks of up to 3 months. The activity can begin with strong vulcanian explosions, as in May 2010, December 2012 and July 2013; or with strombolian explosions and continuous emission of gases and ash.
