🇪🇨 Ecuador · Sierra (Andean Highlands)
Tungurahua is one of Ecuador's most active and emblematic volcanoes, an imposing cone rising 5,023 meters above the town of Baños de Agua Santa, in the central highlands. Nicknamed the 'Black Giant', it has gone through intense eruptive periods in recent decades, with explosions, ash columns and, at night, spectacular incandescent flows that turned it into a stage as feared as it is fascinating.
Its name, of Kichwa origin, is usually read as 'throat of fire' (from 'tunguri', throat, and 'rahua', fire), a very fitting description for a mountain that spits fire. The volcano is part of Sangay National Park and dominates the landscape of Baños, the lively tourist town at its foot, which lives in the shadow —and to the rhythm— of its activity.
This guide approaches Tungurahua with a practical and prudent eye: how and where to view it safely (viewpoints such as Bellavista or the Casa del Árbol, in Baños), what to bear in mind given that it is an active volcano, its relationship with life in Baños and the hot springs around it, and why the climb to its summit depends on volcanic activity.
Tungurahua is a stratovolcano with a long eruptive history, with eruptions documented in colonial and republican times that repeatedly affected Baños and its surroundings. After decades of calm, it resumed activity in 1999, forcing the evacuation of Baños, and it kept up intense eruptive episodes in the following years. For Andean peoples it is a sacred mountain, often presented as 'Mama Tungurahua'. The full version is on our history page.

Origins, formation and what the sources say.
On the night of 16 August 2006, the sky over Baños de Agua Santa turned an orange nobody would forget. At seven in the evening, Tungurahua entered its most violent eruption since it had woken in 1999: for hours it threw up ash columns kilometers high and, down its western flanks, some twenty pyroclastic flows began to descend —avalanches of gas and incandescent rock at more than 40 km/h and hundreds of degrees— destroying everything in their path. The hamlets of Palitagua, Chilibu, Choglontúz, Cusúa and Bilbao were devastated: pastures, crops, animals and houses vanished under the burning material. Seven people died, most of them in Palitagua, in an area that had been considered safe. It was the most tragic episode of an eruptive cycle that would go on until 2016.
And yet the story of Tungurahua is not only one of disaster. It is the story of a town that, season after season, evacuation after evacuation, decided to go on living at the foot of a giant of fire. It is the story of a mountain that Andean peoples venerated as a deity, that gave Baños its healing hot springs and that, even in its most furious years, drew travelers who climbed to the viewpoints at night to watch the summit burn. This is the story of how you live with an active volcano: between fear and fascination, between ash and tourism, between science and faith.
For the Andean peoples of what is now central Ecuador, Tungurahua was always much more than a mountain: a living, powerful, sacred being. In the Andean worldview, the great volcanoes are beings with will and character, often represented as male or female figures who form relationships with one another. Tungurahua is usually presented as a female figure, 'Mama Tungurahua', linked in the legends with other neighboring volcanoes of the region.
Its very name reveals how it was perceived: derived from Kichwa, it is usually read as 'throat of fire' (from 'tunguri', throat, and 'rahua', fire or ember), a precise description of a volcano that, throughout history, has spat fire, ash and incandescent rock. That fiery nature fed stories, fears and rituals among the communities living around it.
The relationship of these peoples with Tungurahua was marked, then, by a mixture of veneration and fear. The volcano was a source of fertility —its ash enriches the soil, its hot springs heal— but also of destruction. That duality, common to many Andean volcanoes, sits at the heart of the region's identity and explains why, even today, the 'Black Giant' holds such a central place in the local imagination.
Tungurahua is an explosive stratovolcano with a documented eruptive history going back centuries. During the colonial and republican periods, it went through several major eruptive episodes that repeatedly affected the settlements around it, especially the Baños area, which sits right at its foot. Eruptions in the 18th, 19th and 20th centuries left records of ashfall, flows and damage, and forged in local memory the awareness of living next to a dangerous volcano.
After a long period of relative calm through much of the 20th century, Tungurahua woke dramatically in late 1999. The reactivation forced the authorities to evacuate the town of Baños and other settlements in the face of the risk of a major eruption. That evacuation, and the later and controversial return of residents who refused to abandon their homes and livelihoods for good, deeply marked the recent history of the region.
From then on and for several years, the volcano kept up intense, intermittent activity, with explosions, ash columns that affected farming and health, dangerous pyroclastic flows in some phases and, at night, spectacular incandescent emissions that drew both unease and curiosity. Tungurahua thus became one of the most closely watched volcanoes in Ecuador and a case study in how communities live with volcanic risk.
The reactivation of Tungurahua tested the capacity of communities and of the state to live with an active volcano. A permanent monitoring system was set up, run by the Instituto Geofísico, with instruments watching seismic activity and emissions, and evacuation plans, alert systems and the organization of residents themselves —the famous community 'vigías', or lookouts— were developed to respond to danger. This experience is cited as an example of volcanic risk management with community participation.
Paradoxically, the volcano's activity also boosted tourism. Baños de Agua Santa, at its foot, consolidated its fame as a tourist destination, and the smoking mountain itself became an attraction: viewpoints such as the Casa del Árbol were born, in part, as observation posts for the volcano, and later turned into tourist icons. Watching the incandescent glow of Tungurahua at night became, in certain phases, a spectacle that drew visitors.
That tension between risk and appeal defines the relationship with Tungurahua today. The mountain is still an active volcano, part of Sangay National Park, whose activity should be checked before any ascent or close visit. But it is also the majestic backdrop of one of the liveliest tourist regions in Ecuador, where the hot springs it heats and the landscapes it dominates are a constant reminder that you live in the shadow of a giant of fire.
The reactivation of late 1999 opened one of the longest and most closely observed eruptive cycles in Ecuador's recent history. For more than fifteen years, Tungurahua alternated phases of relative calm with episodes of strong activity. The most violent came in July and August 2006: the eruption of 16–17 August, with a volcanic explosivity index (VEI) of 3, generated some twenty pyroclastic flows that raced down the ravines of the western flanks, destroyed the hamlets of Palitagua, Cusúa, Bilbao, Chilibu and Choglontúz and left seven dead, the gravest moment of the whole period. About 3,200 people were evacuated. There were further significant eruptive pulses in 2008, 2010, 2011, 2013 and 2014, each with ashfall, road closures and precautionary evacuations.
The last major eruptive episode was recorded around 2016, after which the volcano entered a phase of declining activity. Since then, the Instituto Geofísico has reported Tungurahua at low levels —as of mid-2026 it remains on white alert, with very low internal and surface activity and no forecast of reactivation in the short or medium term— without the explosions and lava flows that characterized the previous two decades, although it keeps its status as an active volcano under permanent watch.
That relative calm allowed Baños and its surroundings to rebuild their tourist life without the constant threat of ash, but the memory of the years of activity is still present. Residents and authorities live with the certainty that the 'Black Giant' can wake again, so monitoring and contingency plans remain active as part of everyday life in the region.
