Tungurahua Volcano — Ecuador's Throat of Fire & UNESCO Geopark

Geography PRELIMS World Geography UNESCO Global Geopark
PRELIMS Geography · World Geography · UNESCO Global Geopark
Tungurahua Volcano — meaning "Throat of Fire" in the Quichua (Kichwa) language — is a highly active stratovolcano located in the Cordillera Oriental of the central Andes, Ecuador, rising to 5,023 m above sea level. On 10 April 2025, the UNESCO Executive Board officially designated the surrounding territory as a UNESCO Global Geopark, making it one of 16 new geoparks that expanded the global network to 229 sites in 50 countries. This question appeared directly in UPSC Prelims 2026 (GS Paper I, Q.21) — making it one of the most important geography current affairs of the 2025–26 cycle. The geopark spans 2,397 km² across Tungurahua and Chimborazo provinces, preserving over 417 million years of geological history.

Current network (2025)229 geoparks in 50 countries · ~855,000 km² total area

Tungurahua — Etymology & Basic Identity

Name, Language & Type Classification
ParameterDetail
NameTungurahua
Language of OriginQuichua (Kichwa) — the language of the Incas, still spoken by the Salasaca & Puruhá peoples
EtymologyTunguri = Throat / Rahua = Fire → "Throat of Fire"
Informal name"Mama" (by local communities)
Volcano TypeStratovolcano (also called composite volcano)
StatusActive — ongoing since 1999; last eruption 2016
UNESCO Geopark YearApril 2025 (Executive Board designation; official welcome ceremony June 2, 2025 at UNESCO HQ, Paris)
Geological History SpanOver 417 million years
📌 Micro-Fact

The UNESCO Global Geopark designation is UNESCO's third and newest natural designation — created in 2015, it joins World Heritage Sites (1972) and Biosphere Reserves (MAB Programme, 1971).

💡 Exam Tip

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.

Core One-Liner: Tungurahua = "Throat of Fire" in Quichua · Active stratovolcano in Ecuador's Cordillera Oriental · UNESCO Global Geopark designated April 2025 · 229th in the global network.

Geological & Scientific Details

Stratovolcano — Structure & Type

Volcanic Classification & Scientific Profile
ParameterDetail
Volcano TypeStratovolcano / Composite Volcano
Rock TypeAndesitic to dacitic (andesite–dacite)
Eruption StyleStrombolian to Vulcanian (explosive) · also pyroclastic flows + lava flows
Tectonic SettingSubduction zone — Nazca Plate (oceanic) subducting beneath South American Plate (continental) at ~5–7 cm/year
Tectonic ZonePacific Ring of Fire (eastern Andean belt)
Summit glacierSmall summit glacier (now largely melted due to increased volcanic activity post-1999)
Total volume (remaining edifice)~110 km³
Last eruption1999–2017 (continuous); last major episode 26 Feb – 16 Mar 2016
Largest known eruption~1010 BC — sub-Plinian, VEI 4

Tectonic Setting — Nazca Plate & Ring of Fire

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.

Key Hazard Types from Tungurahua Eruptions
Hazard TypeDescriptionThreat Level
LaharsMeltwater + ash + debris flows racing down valleys at up to 50 km/hrHighest — threatens Baños directly
Pyroclastic FlowsFast-moving hot gas + volcanic material; dense & deadlyHigh on steep flanks
Tephra / Ash FallsFine volcanic ash deposited over wide areasDisrupts agriculture & air travel
Lava FlowsGenerally stop within a few km of the ventModerate (localised)
Sector CollapseCatastrophic flank failure (like ~3,000 years ago); debris up to 15 kmLow frequency but high impact
📌 Micro-Fact

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.

Three Volcanic Edifices (Tungurahua I, II, III)

Construction History — Three Successive Edifices
EdificeBuilt (approx.)Key Fact
Tungurahua I~293–79 ka (mid-Pleistocene)~125 km³ andesitic to dacitic stratocone; ~14 km wide; collapsed (reason unclear)
Tungurahua IIPast ~14,000 yearsBuilt 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 – presentModern glacier-capped cone built inside II's landslide scarp; ~50% of pre-collapse size; rebuilt from ~3 km³ of erupted products
💡 Exam Tip

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.

Science Hook: Tungurahua = active stratovolcano · Nazca Plate subduction → Andean NVZ · Three edifices built over 300,000 years · Lahars = primary hazard · Sector collapse 3,000 years ago left horseshoe caldera.

Historical Evolution

Eruption Timeline — Key Historical Events

~1010 BC
Largest known eruption — sub-Plinian, VEI 4; ash plume spread over 740 × 180 km.
~3,000 years ago
Sector collapse of Tungurahua II → horseshoe-shaped caldera; debris avalanche traveled 15 km to the west; modern Tungurahua III cone began building within the scar.
1640–1646
First well-documented major eruptive episode since European settlement (1532). Villages near the flanks severely affected.
1773–1781
Major eruption produced large debris flow descending Vazcún valley toward Baños. Pastaza River temporarily dammed. "Belching fire, lightning, sand, ash" recorded (23 April 1773).
1797 & 1949
Major earthquakes (not eruptions) devastated towns of Guano, Pelileo, and Patate — both towns now within the geopark's area.
1886–1888
Second recorded major historical eruption; pyroclastic flows reached populated areas at the volcano's base.
1916–1918
Third major historical eruption; minor activity continued until 1925. Preceded by ~80 years of dormancy before 1999 reactivation.
1999–2017
Long-term reactivation beginning 19 August 1999; forced temporary evacuation of 25,000 people from Baños; continuous activity for 17+ years; lahars up to 3×/week at peak. Baños recognised as a global model for volcanic resilience.
2016 (Last major episode)
26 Feb – 16 Mar 2016: Ash plumes 3–8 km high; pyroclastic flows in ravines; incandescent blocks ejected 1,500 m down flanks; significant SO₂ emissions. Currently dormant (monitoring continues).
2024 (Baños Landslide)
16 June 2024: Landslide (not eruption) struck highway in Baños due to heavy rainfall → 8 deaths, 11 missing. Underlines ongoing geo-hazard risk in the area.
10 April 2025
UNESCO Executive Board officially designates Tungurahua Volcano as a UNESCO Global Geopark — one of 16 new geoparks; network reaches 229 sites in 50 countries.
2 June 2025
UNESCO hosts welcome ceremony at UNESCO HQ (Paris) for all 16 new geoparks. Coordinator Myriam Piray Quezada represents the Tungurahua Geopark.
📌 Micro-Fact

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.

History Hook: Key eruptions: 1640–46 · 1773–81 · 1886–88 · 1916–18 · 1999–2017 · Earthquakes 1797 & 1949. UNESCO Geopark designated April 10, 2025.

⚠ Common Trap

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.

Statement True/False Traps Table

Common Statement-Based Trap Questions on Tungurahua & UNESCO Geoparks
Statement✅/❌Reason
Tungurahua means "Throat of Fire" in QuichuaTunguri (throat) + Rahua (fire) = Throat of Fire; correct etymology
Tungurahua is an extinct volcanoIt is highly ACTIVE; last erupted 2016; reactivated 1999 after 80 years' dormancy
Tungurahua Geopark was designated in 2024Designation was 10 April 2025, not 2024
Tungurahua is located in Cordillera Occidental of EcuadorIt is in Cordillera ORIENTAL (Eastern Cordillera); not Occidental (Western)
The UNESCO Global Geopark designation was established in 2004GGN was founded in 2004 as a non-UNESCO body; UNESCO designation (IGGP) was established in 2015
India has 2 UNESCO Global Geoparks as of 2025India has ZERO UNESCO Global Geoparks
Geopark designation is permanent once grantedDesignation 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 areaSangay NP = UNESCO Natural WHS (1983); it overlaps with Tungurahua Geopark area (separate designation)
Tungurahua Geopark spans across 5 countriesIt is entirely within Ecuador, spanning only 2 provinces (Tungurahua + Chimborazo)
Lahars from Tungurahua can travel at 50 km/hrVerified — lahars (meltwater + ash + debris) race down narrow valleys at up to 50 km/hr
⚠ Trap 1 — GGN Founded (2004) ≠ UNESCO Designation (2015)

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.

⚠ Trap 2 — Cordillera Oriental vs Occidental

Tungurahua is in Cordillera Oriental (Eastern Range), NOT Cordillera Occidental (Western Range). The two cordilleras form Ecuador's Andean spine — many students confuse them.

⚠ Trap 3 — Ecuador had TWO new Geoparks in 2025

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.

⚠ Trap 4 — Geopark ≠ World Heritage Site

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.

⚠ Trap 5 — Total Geoparks: 229 (April 2025) → potentially 241 (2026)

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.

PYQ Verdict: Tungurahua appeared in UPSC Prelims 2026 Q.21 — Ecuador is the answer. Know: Cordillera Oriental · Active (not extinct) · IGGP 2015 · 4-year revalidation · India = 0 Geoparks.

MCQ Practice
1Tungurahua Volcano, which was designated a UNESCO Global Geopark in 2025, is located in which of the following mountain ranges?
Correct: (b) Cordillera Oriental, Ecuador

Tungurahua is located in the Cordillera Oriental (Eastern Cordillera) of the Ecuadorian Andes — NOT the Occidental (Western) range. Cordillera Blanca is Peru's and Cordillera Real is Bolivia's. Key memory: ORIENT(AL) = EAST = Ecuador's volcanic belt where Tungurahua sits, roughly 120 km south of Quito.
2Consider the following statements about UNESCO Global Geoparks:
1. The designation was established by UNESCO in 2015 under the International Geoscience and Geoparks Programme (IGGP).
2. Designation is permanent once granted, with no periodic review.
3. India has no UNESCO Global Geopark as of 2025.
Which of the above statements is/are correct?
Correct: (c) 1 and 3 only

Statement 1 ✅: IGGP (UNESCO) was adopted on 17 November 2015 at the 38th UNESCO General Conference. Statement 2 ❌: Designation is NOT permanent — it is for 4 years and subject to revalidation (Green/Yellow/Red card system). Statement 3 ✅: India has ZERO UNESCO Global Geoparks despite tentative lists maintained by GSI. The Geological Survey of India + UNESCO held India's first Geopark training workshop in September 2024.
3With reference to the April 2025 batch of UNESCO Global Geoparks, which two countries joined the UNESCO Global Geoparks Network for the FIRST TIME?
Correct: (c) North Korea and Saudi Arabia

The April 2025 batch of 16 new geoparks across 11 countries included the FIRST-EVER geoparks for DPRK (Mt Paektu — site of the famous Millennium Eruption ~1000 CE) and Saudi Arabia (North Riyadh + Salma). Ecuador, Indonesia, Vietnam, Norway, Italy, and Spain already had geoparks and received additional new ones in this batch.
4Tungurahua Volcano is formed due to the subduction of which tectonic plate beneath the South American Plate?
Correct: (c) Nazca Plate

All of Ecuador's Andean volcanoes — including Tungurahua, Cotopaxi, Sangay, and Cayambe — are formed by the subduction of the oceanic Nazca Plate beneath the continental South American Plate along the Pacific Ring of Fire. The Cocos Plate drives volcanism in Central America; the Caribbean Plate is to Ecuador's north. The Pacific Plate itself does not directly subduct under South America here — the Nazca Plate is the intermediary oceanic plate.
5Consider the following pairs — Geopark and its Country (all from the April 2025 UNESCO batch):
1. Tungurahua Volcano — Ecuador
2. Napo Sumaco — Colombia
3. Mt Paektu — Democratic People's Republic of Korea
4. Kanbula — China
Which of the pairs is/are correctly matched?
Correct: (d) 1, 3 and 4 only — i.e., Pairs 1, 3 and 4 are correct.

Pair 1 ✅: Tungurahua Volcano — Ecuador. Pair 2 ❌: Napo Sumaco is in ECUADOR (not Colombia) — both Ecuador geoparks are from the same April 2025 batch. Pair 3 ✅: Mt Paektu — DPRK (North Korea), famous for the Millennium Eruption ~1000 CE. Pair 4 ✅: Kanbula — China (on the Qinghai-Tibet Plateau, features ancient Maixiu volcanoes and the Yellow River). Note that this matches option (b) as well — but (d) is the intended correct framing since pair 2 is wrong.
MCQ Pattern: Expect location questions (Ecuador vs others) · statement true/false combos · pair-matching of geopark and country · tectonic plate identification · IGGP 2015 date · India's zero-geopark status.
