UPSC often asks: "In which country is Tungurahua Volcano located?" — Answer: Ecuador. The confusers are Peru, Bolivia, and Colombia — all Andean nations but NOT Tungurahua's home. Remember: Tungurahua → Equator → Ecuador.
| Parameter | Detail |
|---|---|
| Country | Ecuador (South America) |
| Continent | South America |
| Mountain Range | Cordillera Oriental (Eastern Cordillera) of the Andes |
| Volcanic Zone | Northern Volcanic Zone (NVZ) of the Andes |
| Coordinates | 1°28′S, 78°27′W |
| Province (Volcano Name) | Tungurahua Province (gives name to the province) |
| Geopark provinces | Tungurahua Province + Chimborazo Province |
| Five cantons covered | Baños de Agua Santa · Patate · Pelileo · Guano · Penipe |

| Distance from Quito | ~120 km south (some sources: 135–140 km) |
| Gateway town | Baños de Agua Santa (~8 km from crater; ~20,000 residents) |
| Feature | Detail |
|---|---|
| Principal Rivers | Pastaza · Chambo · Puela (encircle the volcanic cone) |
| Major River Valley | Upper Pastaza Valley (lahar corridor; Amazon tributary) |
| Protected Areas within Geopark | Llanganates National Park · Sangay National Park · Chimborazo Fauna Production Reserve · Zuñag · La Candelaria |
| Sangay NP status | UNESCO World Heritage Site (Natural, 1983); contains Tungurahua + Sangay volcanoes + El Altar (extinct) |
| Landscape features | Deep canyons · Crystal-clear rivers · Icy waterfalls · Towering rock walls · Cloud forests · Thermal hot springs |
| Thermal springs | Magma heats underground water → mineral-rich therapeutic hot springs at Baños de Agua Santa |
| Basal diameter of cone | 14 km |
| Relief (cone above base) | >3,200 m extreme relief (3 km above northern base) |
Baños de Agua Santa is famous for its thermal baths, adventure tourism (rafting on Pastaza), the "Casa del Árbol" swing overlooking the volcano, and "La Ruta de las Cascadas" — all within the geopark's tourism zone.
| Parameter | Detail |
|---|---|
| Volcano Type | Stratovolcano / Composite Volcano |
| Rock Type | Andesitic to dacitic (andesite–dacite) |
| Eruption Style | Strombolian to Vulcanian (explosive) · also pyroclastic flows + lava flows |
| Tectonic Setting | Subduction zone — Nazca Plate (oceanic) subducting beneath South American Plate (continental) at ~5–7 cm/year |
| Tectonic Zone | Pacific Ring of Fire (eastern Andean belt) |
| Summit glacier | Small summit glacier (now largely melted due to increased volcanic activity post-1999) |
| Total volume (remaining edifice) | ~110 km³ |
| Last eruption | 1999–2017 (continuous); last major episode 26 Feb – 16 Mar 2016 |
| Largest known eruption | ~1010 BC — sub-Plinian, VEI 4 |
Tungurahua sits in the Northern Volcanic Zone (NVZ) of the Andes, formed entirely by the subduction of the Nazca Plate beneath the South American Plate. As the dense oceanic Nazca Plate descends into the mantle, intense heat and pressure melt mantle rock into magma, which rises through the crust to form the Andean volcanic chain — including Tungurahua, Cotopaxi, Sangay, Antisana, and Cayambe.
| Hazard Type | Description | Threat Level |
|---|---|---|
| Lahars | Meltwater + ash + debris flows racing down valleys at up to 50 km/hr | Highest — threatens Baños directly |
| Pyroclastic Flows | Fast-moving hot gas + volcanic material; dense & deadly | High on steep flanks |
| Tephra / Ash Falls | Fine volcanic ash deposited over wide areas | Disrupts agriculture & air travel |
| Lava Flows | Generally stop within a few km of the vent | Moderate (localised) |
| Sector Collapse | Catastrophic flank failure (like ~3,000 years ago); debris up to 15 km | Low frequency but high impact |
The Agoyan hydroelectric dam on the Pastaza River — Ecuador's second most important dam — lies directly downstream and is threatened by future large eruptions of Tungurahua.
| Edifice | Built (approx.) | Key Fact |
|---|---|---|
| Tungurahua I | ~293–79 ka (mid-Pleistocene) | ~125 km³ andesitic to dacitic stratocone; ~14 km wide; collapsed (reason unclear) |
| Tungurahua II | Past ~14,000 years | Built within I's collapse scar; itself collapsed ~3,000 years ago → horseshoe caldera open to west; debris-avalanche up to 15 km |
| Tungurahua III (Current) | ~2,300 years ago – present | Modern glacier-capped cone built inside II's landslide scarp; ~50% of pre-collapse size; rebuilt from ~3 km³ of erupted products |
UPSC may ask about types of volcanic hazards. Lahars are the primary civil-protection challenge around Tungurahua — not lava flows. Lahars can travel at 50 km/hr and directly threaten the ~20,000 residents of Baños.
Since 1900, Tungurahua has had 28 eruptions and been active during 28 years out of 127 — erupting on average once every 4.5 years. Ecuador's indigenous Puruhá people historically revered the volcano as a deity; eruptions were seen as divine messages.
| Parameter | Detail |
|---|---|
| Total Area | 2,397 km² |
| Provinces | Tungurahua Province + Chimborazo Province |
| Five Municipalities (Cantons) | Baños de Agua Santa · Patate · Pelileo · Guano · Penipe |
| Governance Body | Decentralised Autonomous Provincial Governments of Tungurahua and Chimborazo + Municipal Governments of the 5 cantons |
| Geopark Coordinator | Myriam Piray Quezada |
| Framework followed | Sendai Framework for Disaster Risk Reduction (priority spheres embedded in governance) |
| Geological history span | Over 417 million years |
| Protected areas included | Llanganates NP · Sangay NP · Chimborazo Fauna Production Reserve · Zuñag · La Candelaria |
| River basins | Patate · Chambo · Pastaza (all within geopark zone) |
| Group | Location | Cultural Significance |
|---|---|---|
| Salasaca | Tungurahua Province (between Ambato & Baños) | Hand-woven tapestries on ancient looms; market at "Plaza of the Arts"; speak Quichua + Spanish |
| Puruhá | Chimborazo Province | Distinctive clothing, music, dance; ancestral storytelling; revered Tungurahua as deity |
| Kichwa (Quichua) broadly | Tungurahua + Amazon foothills | Traditional knowledge of soil, water, volcanic signs; guides reforestation; named the volcano "Mama" |
Baltazar Ushca — "The Last Iceman of Chimborazo" — was a cultural icon of the Puruhá people and ambassador of the geopark who upheld the ancestral tradition of harvesting ice from Chimborazo's glaciers. He symbolises the deep connection between people, place, and nature.
| Initiative | Description |
|---|---|
| GeoAmigo Cafeteria "Casa del Volcán" | Owned by local resident Indira Medina; volcanic-theme café using local farm ingredients; ancestral dishes with contemporary twist |
| Las Caras Tourist Complex | Petrified tree roots and carved rock faces attributed to ancestral Killuyakus people; educational tours, horseback rides, volcanic mineral mud treatments |
| Guamag Protected Forest | 207 hectares near Sangay and Llanganates NPs; guided tours, eco-friendly accommodation, environmental education |

| Disaster Resilience Model | Baños internationally recognised after 1999–2016 eruptions for effective risk management, evacuation planning, and post-eruption economic diversification |
The geopark explicitly follows the Sendai Framework for Disaster Risk Reduction in its governance — linking UNESCO's geological heritage programme to the UN's disaster risk reduction framework. This is an important inter-linkage UPSC could test.
| Parameter | UNESCO Global Geopark | World Heritage Site | Biosphere Reserve |
|---|---|---|---|
| Programme | IGGP (2015) | World Heritage Convention (1972) | Man & Biosphere (MAB, 1971) |
| Focus | Geological heritage · Geodiversity · Geotourism · Sustainable development | Conservation of outstanding universal cultural/natural value | Harmonised management of biological & cultural diversity |
| Approach | Bottom-up (community-led) | State nomination-based | State nomination-based |
| Designation Period | 4 years (renewable; revalidated) | Permanent (unless delisted) | Permanent |
| India's count (2025) | Zero — India has NO UNESCO Global Geopark | 40+ World Heritage Sites | 18 notified (12 in WNBR) |
| Legal protection | No mandatory legal regime (national laws apply) | Mandatory conservation obligations | No mandatory legal regime |
| Revenue/tourism | Explicitly promotes geotourism & local economic development | Conservation primary; tourism secondary | Sustainable use of biodiversity |
UNESCO Global Geoparks are NOT a subset of World Heritage Sites — they are a separate, third UNESCO designation. A geopark CAN overlap with a WHS but must be independently branded and justified. Sangay National Park (which includes Tungurahua) IS a UNESCO WHS — but the Tungurahua Geopark is a separate additional designation.
| Volcano | Country | Height | Key Feature |
|---|---|---|---|
| Tungurahua | Ecuador | 5,023 m | UNESCO Geopark 2025; "Throat of Fire"; active 1999–2017 |
| Cotopaxi | Ecuador | 5,897 m | World's highest active volcano; Northern Volcanic Zone |
| Sangay | Ecuador | 5,230 m | One of world's most continuously active; in Sangay NP (UNESCO WHS) |
| Mt Paektu | North Korea | 2,744 m | UNESCO Geopark 2025 (first for DPRK); Millennium Eruption ~1000 CE |
| Vesuvius | Italy | 1,281 m | Classic stratovolcano; destroyed Pompeii 79 CE |
| Mt Fuji | Japan | 3,776 m | Classic stratovolcano; UNESCO WHS 2013; last erupted 1707 |
| Barren Island | India (Andaman) | 354 m | India's only active volcano; stratovolcano; South Asia's Ring of Fire |
| Nevado del Ruiz | Colombia | 5,321 m | Active stratovolcano; 1985 eruption + lahar killed ~23,000 |
Both Tungurahua and Mt Paektu (North Korea) became UNESCO Global Geoparks in April 2025 — from the same batch of 16 new designations. This is a common pairing question UPSC may exploit.
| Card | Meaning | Consequence |
|---|---|---|
| 🟢 Green Card | Geopark meets all criteria | Designation renewed for 4 more years |
| 🟡 Yellow Card | Criteria partially met | 2-year window to address recommendations |
| 🔴 Red Card | Criteria not met within 2 years | Geopark loses UNESCO designation |
| Linked Topic | Connection to Tungurahua |
|---|---|
| Pacific Ring of Fire | Tungurahua is part of the Ring of Fire — the horseshoe-shaped belt accounting for 75% of world's volcanoes and 90% of earthquakes; Ecuador lies on its western South American arc |
| Nazca Plate Subduction | Oceanic Nazca Plate subducts under the South American Plate → generates magma → feeds Tungurahua and all Ecuadorian Andes volcanoes |
| Sangay National Park | UNESCO World Heritage Site (Natural, 1983) overlapping with the geopark area; contains Tungurahua + Sangay (active) + El Altar (extinct); altitudinal range 900–5,319 m; 327 lakes |
| UNESCO's IGGP | Geopark established under IGGP, UNESCO's flagship Earth Sciences programme (10th anniversary, March 2025); India is pursuing its first nomination under this programme |
| Sendai Framework | Geopark governance explicitly aligns with Sendai Framework priorities for disaster risk reduction — linking geohazard management to the UN's global DRR framework |
| Lahars & Volcanic Hazards | Tungurahua is a globally studied lahar-hazard case study; early warning systems developed here are models for other volcanic regions |
| Indigenous Knowledge | Kichwa/Salasaca communities' traditional knowledge of volcanic signs, soil, and water informs geopark co-management — relevant to UPSC GS III (environment + traditional knowledge) |
| Climate Change | Ecuador's glaciers shrank 54% since 1980 (2022 UN report); Tungurahua's summit glacier has melted; increased glacial melt intensifies lahars — a direct climate–volcano link |
As of April 2025, India has ZERO UNESCO Global Geoparks. India has ~100 geo-heritage sites but only 32 are declared National Geological Monuments. The Geo Heritage Sites and Geo-relics Bill, 2022 was drafted but not yet passed.
| Site | State | Geological Significance |
|---|---|---|
| Lonar Crater Lake | Maharashtra | One of world's largest basaltic impact craters; ~50,000 years old; formed by meteorite |
| St. Mary's Islands & Malpe Beach | Karnataka | Columnar basaltic lava formations |
| Siwalik Fossil Park | Himachal Pradesh | Rich Miocene–Pleistocene fossil record |
| Deccan Traps / Deccan Plateau | Deccan region | Massive flood basalt province; 65 Ma; linked to mass extinction debate |
| Dinosaur Fossil Park, Raiyoli | Gujarat | Key paleontological site; GSI actively pursuing geopark status |
| Barren Island | Andaman & Nicobar | India's only active volcano; stratovolcano; in Ring of Fire |
In September 2024, UNESCO and the Geological Survey of India jointly organised India's first-ever Training-cum-Workshop on UNESCO Global Geoparks at UNESCO House, New Delhi. India's Ministry of Mines has reaffirmed intent to nominate at least one geopark by 2028.
On 10 April 2025, the UNESCO Executive Board officially designated the Tungurahua Volcano UNESCO Global Geopark in Ecuador as part of a batch of 16 new Global Geoparks across 11 countries. The global network now comprises 229 geoparks in 50 countries, collectively spanning ~855,000 km². (Source: UNESCO Official IGGP, April 2025)
On 2 June 2025, UNESCO hosted a landmark welcome event at its Paris headquarters for the 16 newly designated Global Geoparks. The ceremony brought together managers, national delegations, and partners — many meeting in person for the first time. Myriam Piray Quezada, Coordinator of the Tungurahua Volcano UNESCO Global Geopark, attended as Ecuador's representative. North Korea and Saudi Arabia joined the Global Geoparks Network for the first time. (Source: UNESCO.org, June 2025)
The Tungurahua Volcano UNESCO Global Geopark featured directly as Q.21 in UPSC Civil Services Prelims 2026 (GS Paper I), held on 25 May 2026. The question asked in which country Tungurahua is located — options were Ecuador, Peru, Bolivia, and Colombia. Correct answer: Ecuador. This confirms the topic's highest-priority status for future aspirants as well. (Source: Multiple UPSC coaching answer keys, May 2026)
In September 2025, the UNESCO Global Geoparks Council held its 10th session at Kütralkura UNESCO Global Geopark, Chile, accepting 12 additional applications for new geopark designations. If endorsed by UNESCO's Executive Board in 2026, the network would expand to 241 sites worldwide. (Source: UNESCO.org, September 2025)
In September 2024, UNESCO and India's Geological Survey of India (Ministry of Mines) co-organised India's first-ever Training-cum-Workshop on UNESCO Global Geoparks in New Delhi — a milestone step toward India's first nomination. The Ministry of Mines reaffirmed target of nominating at least one site by 2028. India currently has no UNESCO Global Geopark, despite ~100 geo-heritage sites. (Source: UNESCO New Delhi, October 2024)
The 16 new UNESCO Global Geoparks of April 2025 are a hot topic for 2025–26 exams. Key first-timers: North Korea (Mt Paektu) and Saudi Arabia (North Riyadh + Salma). Ecuador had TWO new geoparks in this batch: Tungurahua Volcano AND Napo Sumaco. The IGGP completed its 10th anniversary in March 2025.
Question: "Tungurahua Volcano, which was declared a Global Geopark by UNESCO in 2025, is situated in which one among the following countries?"
(a) Ecuador (b) Peru (c) Bolivia (d) Colombia
Correct Answer: (a) Ecuador
| Option | Country | Verdict | Why |
|---|---|---|---|
| (a) | Ecuador | ✅ Correct | Tungurahua is in Cordillera Oriental of Ecuador; designated UNESCO Geopark April 2025 |
| (b) | Peru | ❌ Wrong | Peru shares Andes & Ring of Fire but its famous volcanoes are El Misti and Ubinas — NOT Tungurahua |
| (c) | Bolivia | ❌ Wrong | Bolivia's famous geological features: Salar de Uyuni, Sajama, Uturuncu — no Tungurahua |
| (d) | Colombia | ❌ Wrong | Colombia's stratovolcanoes: Nevado del Ruiz, Galeras — Tungurahua is south of Colombia, in Ecuador |
| Statement | ✅/❌ | Reason |
|---|---|---|
| Tungurahua means "Throat of Fire" in Quichua | ✅ | Tunguri (throat) + Rahua (fire) = Throat of Fire; correct etymology |
| Tungurahua is an extinct volcano | ❌ | It is highly ACTIVE; last erupted 2016; reactivated 1999 after 80 years' dormancy |
| Tungurahua Geopark was designated in 2024 | ❌ | Designation was 10 April 2025, not 2024 |
| Tungurahua is located in Cordillera Occidental of Ecuador | ❌ | It is in Cordillera ORIENTAL (Eastern Cordillera); not Occidental (Western) |
| The UNESCO Global Geopark designation was established in 2004 | ❌ | GGN was founded in 2004 as a non-UNESCO body; UNESCO designation (IGGP) was established in 2015 |
| India has 2 UNESCO Global Geoparks as of 2025 | ❌ | India has ZERO UNESCO Global Geoparks |
| Geopark designation is permanent once granted | ❌ | Designation is for 4 years; subject to revalidation (Green/Yellow/Red card system) |
| Sangay National Park (Ecuador) is both a UNESCO WHS and part of the Geopark area | ✅ | Sangay NP = UNESCO Natural WHS (1983); it overlaps with Tungurahua Geopark area (separate designation) |
| Tungurahua Geopark spans across 5 countries | ❌ | It is entirely within Ecuador, spanning only 2 provinces (Tungurahua + Chimborazo) |
| Lahars from Tungurahua can travel at 50 km/hr | ✅ | Verified — lahars (meltwater + ash + debris) race down narrow valleys at up to 50 km/hr |
The Global Geoparks Network (GGN) was announced at the First International Conference on Geoparks in 2004. However, UNESCO's formal programme — IGGP — was adopted only on 17 November 2015. UPSC may test this distinction.
Tungurahua is in Cordillera Oriental (Eastern Range), NOT Cordillera Occidental (Western Range). The two cordilleras form Ecuador's Andean spine — many students confuse them.
The April 2025 batch included BOTH Tungurahua Volcano Geopark AND Napo Sumaco Geopark from Ecuador. Don't confuse or conflate the two. Tungurahua = volcano + Andes. Napo Sumaco = Amazon region.
A UNESCO Global Geopark and a UNESCO World Heritage Site are two completely separate designations. Sangay NP is a UNESCO WHS — but the Tungurahua Geopark is NOT the same as Sangay NP's WHS status; it's an additional, independently branded designation.
As of April 2025 designation: 229 geoparks in 50 countries. In September 2025, the Geoparks Council approved 12 more applications — if UNESCO's Executive Board endorses them, the total reaches 241. Be careful about which year/count appears in a question.
