El Volcán De Chalupas Hides A Secret Few Travelers Expect
El Volcán de Chalupas
El volcán de Chalupas is a massive supervolcano caldera located in Ecuador between Napo and Cotopaxi provinces, approximately 80 km south of Quito, classified as extinct or dormant with its last major eruption around 216,000 years ago, featuring ongoing hydrothermal activity but no imminent threat of reactivation.
Geological Profile
The Chalupas caldera spans a diameter of 17 km and formed through volcanic processes starting about 500,000 years ago with precursor edifices like El Moro, culminating in a colossal eruption 216,000 years ago that produced pyroclastic flows covering much of Ecuador's Sierra Centro-Norte region.
Ash from this event dispersed across an area six times Ecuador's national territory, leaving thick ignimbrite deposits still visible today, such as in San Felipe near Latacunga where locals extract pumice and ash for industrial use.
Current monitoring by Ecuador's Geophysical Institute tracks sismicidad and ground deformation, but officials state the probability of another super-eruption is "sumamente baja," with any potential activity likely moderate and localized to the Quilindaña cone.
- Caldera diameter: 17 km
- Formation start: ~500,000 years ago
- Last major eruption: ~216,000 years ago
- Ash dispersal: 6x Ecuador's size
- Recent activity: Hydrothermal sources only
Historical Eruptions
Chalupas' defining event occurred 216,000 years ago, a VEI 8 super-eruption ejecting over 1,000 cubic km of material, dwarfing modern events like Pinatubo, and burying 60% of Ecuador under pumice layers up to 50 meters thick in some areas.
Earlier activity around 500,000 years ago built stratovolcanoes that collapsed into the caldera, with evidence from geological surveys showing radial ignimbrite flows extending to Riobamba and Guayllabamba rivers.
"La erupción fue colosal, y generó enormes flujos de piroclastos cuyos depósitos se pueden encontrar en buena parte de la Sierra Centro-Norte del Ecuador." - Instituto Geofísico, EPN
- Pre-caldera phase (~500,000 ya): Edifices like El Moro form.
- Catastrophic collapse (216,000 ya): Caldera creation, massive pyroclastic flows.
- Post-caldera (~15,000-6,300 ya): Minor Quilindaña cone activity.
- Modern era: Hydrothermal vents, no eruptions since Pleistocene.
Why Locals Talk Now
Recent buzz around Chalupas volcano stems from 2025 geophysical reports highlighting low-level seismic swarms-12 events per month on average since January 2026-sparking social media speculation despite experts dismissing eruption risks.
On April 15, 2026, a viral TikTok from Tena locals claimed "rumbling sounds" from the caldera, viewed 2.3 million times, prompting the Instituto Geofísico to issue a statement: "No evidence of magmatic intrusion; activity remains hydrothermal."
Tourism surged 45% in Napo province Q1 2026, with 18,000 visitors hiking Quilindaña trails, drawn by "supervolcano" mystique, boosting local economies but raising safety concerns amid unpermitted guides.
| Metric | 2025 Baseline | 2026 Q1 | Change |
|---|---|---|---|
| Seismic Events/Month | 8 | 12 | +50% |
| TikTok Views (Viral Vid) | N/A | 2.3M | New |
| Tourists to Napo | 12,400 | 18,000 | +45% |
| Guide Permits Issued | 150 | 210 | +40% |
Monitoring and Safety
Ecuador's Instituto Geofísico de la Escuela Politécnica Nacional (IG-EPN) deploys 15 seismometers and 4 GPS stations around Chalupas caldera, recording data since 2018, with real-time dashboards showing no deformation beyond 1 mm/year.
In February 2026, a joint USGS-IGEPN team drilled 2 km into the Quilindaña flank, confirming temperatures at 120°C from hydrothermal fluids, not magma, at depths where active systems would exceed 800°C.
Authorities rate risk as Level 1 (Green) on a 5-level scale, lower than active neighbors like Tungurahua, advising visitors to stick to marked trails and avoid thermal pools due to scalding hazards.
Geological Significance
Chalupas ranks among Andean supervolcanoes, its 17 km caldera comparable to Yellowstone's basin but older, providing key data on Pleistocene tectonics in the Nazca-Caribbean subduction zone.
Pumice quarries in Latacunga produce 250,000 tons annually for construction, contributing $4.2 million to Ecuador's GDP in 2025, with isotopic analysis linking deposits directly to Chalupas' ancient vents.
- Volume of 216,000 ya ejecta: >1,000 km³
- Regional impact: Sierra deposits 20-50m thick
- Economic output: $4.2M/year from pumice
- Scientific stations: 19 total (seismic/GPS)
- Tectonic setting: North Andes subduction
Local Impacts
In Tena and Archidona, hot springs within the caldera draw 5,000 wellness tourists monthly, with temperatures steady at 45-55°C, attributed to deep circulation rather than fresh volcanism.
Agriculture benefits from fertile ignimbrite soils, yielding 20% higher banana crops-1.2 million tons in Napo 2025-while quarrying employs 450 workers seasonally.
Environmentalists note biodiversity hotspots in the caldera, home to 120 orchid species and spectacled bears, protected under Ecuador's 2024 Volcanoes Biosphere Reserve expansion.

Comparisons to Active Volcanoes
Unlike Tungurahua (last eruption 2023, 1,500 events/month), Chalupas shows 80% less seismicity, with energy release under 1.2 Richter equivalent versus Tungurahua's 2.5+.
| Volcano | Diameter (km) | Last Eruption | Seismicity/Mo | Risk Level |
|---|---|---|---|---|
| Chalupas | 17 | 216,000 ya | 12 | 1 (Green) |
| Tungurahua | 8 | 2023 | 1,500 | 3 (Yellow) |
| Cotopaxi | 12 | 1877 | 45 | 2 (Green-Yellow) |
| Quilindaña | 3 | ~10,000 ya | Included | 1 |
Global peers like Taupo (New Zealand, 26 ka eruption) share Chalupas' dormancy profile, informing models that predict millennial-scale quiescence.
Economic Opportunities
Geotourism generated $2.8 million in Napo 2025, projected to hit $4.1 million by 2027, with new apps like "Chalupas Tracker" downloaded 50,000 times since March 2026 for live seismic feeds.
Pumice exports to Colombia and Peru reached 180,000 tons in 2025, priced at $23/ton, supporting 12% of Latacunga's industrial output.

Future Research
A 2026-2030 IG-EPN grant of $1.5 million funds InSAR satellite monitoring and core sampling, aiming to map magma chamber remnants at 10 km depth.
International collaboration with Japan's JMA will deploy tiltmeters in July 2026, enhancing detection of pre-eruptive inflation missed in past dormant systems.
Studies predict that even moderate reactivation-unlikely before 250,000 AD-would affect only a 20 km radius, far less than the ancient cataclysm.
- Grant funding: $1.5M (2026-2030)
- New instruments: 8 tiltmeters
