The Canary Islands are one of the most active volcanic island chains in the Atlantic. They are not part of the Pacific Ring of Fire. Instead, they sit above a deep mantle hotspot that builds massive oceanic volcanoes capable of eruptions, earthquake swarms, flank collapses, and occasionally tsunami-generating landslides.
This same long-lived volcanic system continues northeast into the Atlantic through the Madeira volcanic province, forming a connected Canary–Madeira hotspot chain. This pillar is designed as your “301 home” for Canary & Madeira eruption and earthquake stories — a single reference page you can keep updating.
La Palma’s 2021 eruption proved the Canary hotspot is not “ancient geology” — it is a living system that can reshape an island in weeks.
TL;DR — Canary & Madeira in 60 seconds
- The Canaries are built by a mantle hotspot (not a plate boundary).
- La Palma and El Hierro are among the youngest, most active islands.
- Many local quakes come from magma moving underground (swarms) and dike intrusions.
- Big hazards are lava flows, ash/gas, and landslides; tsunamis are mainly linked to large collapses/underwater slides.
- The hotspot chain extends into the Atlantic as the Madeira volcanic province.
The Canary–Madeira Hotspot
Big picture: As the African Plate drifted over a deep mantle heat source, magma repeatedly punched through the oceanic crust, building islands at different times — which is why the Canaries show strong age differences from east to west, and why Madeira belongs in the same broader volcanic province.
What the next map shows: the Canary Islands + Madeira as a single volcanic province, including offshore seamounts and age patterns that hint at long-term hotspot construction.
In practical hazard terms, this structure helps explain why:
- Fuerteventura and Lanzarote are generally older and quieter historically.
- Tenerife and Gran Canaria are intermediate, with complex volcanic histories.
- La Palma and El Hierro are younger and more eruption-prone on human timescales.
- Madeira is quieter today, but still belongs to the same broader hotspot province and has a geologic record of volcanic growth and mass wasting.
How Canary & Madeira volcanoes work
Hotspot volcanism is simple in concept and brutal in consequence: heat rises, rock melts, magma accumulates. When pressure is high enough, magma intrudes upward as dikes, inflating the edifice and generating earthquakes — and sometimes it breaks through as fissure eruptions.
What the next diagram explains: the basic “engine” behind Canary volcanism — a deep mantle plume feeding magma into the African Plate. Think Hawaii but in the Atlantic Ocean.
Common “warning styles” in the Canary system include:
- Earthquake swarms (magma moving, intruding, or pressurizing)
- Ground deformation (inflation/deflation measured by GPS/InSAR)
- Gas changes (CO2, SO2, H2S anomalies)
- Coastal instability where new lava deltas and steep slopes can fail
Most recently active Canary volcanoes (fresh-content magnet)
- La Palma (Cumbre Vieja): last eruption 2021.
- El Hierro: last eruption 2011–2012 (submarine), preceded by intense seismic swarms.
- Tenerife (Teide/Pico Viejo system): last eruption 1909 (Chinyero). High consequence due to exposure; monitoring remains continuous.
- Lanzarote: last eruption 1824 (with the larger Timanfaya episode 1730–1736 as the system-defining historic event).
Clean Canary–Madeira hazard timeline (eruptions, quakes, tsunamis)
Major events (historical + modern)
- 1492 (La Palma): earliest historically recorded Canary eruption (early accounts).
- 1585 (La Palma): major fissure eruption on the Cumbre Vieja system.
- 1706 (Tenerife): eruption that impacted the port area of Garachico (historic benchmark event).
- 1730–1736 (Lanzarote): the Timanfaya-scale eruption sequence — one of the largest historic volcanic episodes in Europe.
- 1798 (Tenerife): Teide rift eruption (Chahorra/Narices del Teide area).
- 1824 (Lanzarote): last historic eruption on the island.
- 1949 (La Palma): Cumbre Vieja fissure eruption with significant ground fracturing.
- 1971 (La Palma – Teneguía): iconic coastal eruption and lava delta growth.
- 2011–2012 (El Hierro): submarine eruption preceded by major seismic swarm and migration.
- 2021 (La Palma – Cumbre Vieja): 85-day eruption: lava flows, ash, gas impacts, widespread destruction, and long-duration seismicity.
- Any time (Canaries/Madeira): landslides and flank failures remain the main tsunami mechanism; most likely impacts are local/regional, but large prehistoric collapses left Atlantic-wide debris fields.
Active volcanoes by island (quick reference table)
| Island | Main volcanic systems | Last eruption (historic) | Primary hazards |
|---|---|---|---|
| La Palma | Cumbre Vieja, Teneguía | 2021 (also 1971, 1949) | Lava flows, ash/gas, seismic swarms, slope instability |
| El Hierro | Submarine volcanic system | 2011–2012 (submarine) | Swarms, submarine eruption hazards, coastal impacts |
| Tenerife | Teide–Pico Viejo rift system | 1909 | High exposure risk, ash/gas, lava flows (scenario dependent) |
| Lanzarote | Timanfaya / rift zones | 1824 (major 1730–1736 episode) | Lava fields, gas hazards, fissure eruptions |
| Gran Canaria | Bandama / older volcanic complexes | Holocene-scale (older than main historic record) | Lower probability, but volcanic terrain hazards exist |
| Fuerteventura | Ancient eroded systems | Very old (geologic timescale) | Low volcanic probability; local seismic/landslide considerations |
| Madeira | Madeira volcanic province (hotspot-related) | Prehistoric (island-scale, not frequent historically) | Steep slopes, landslides; long-term volcanic potential |
La Palma (Cumbre Vieja) – the Canary hotspot’s headline volcano
La Palma’s Cumbre Vieja ridge is one of the most active fissure systems in Europe’s broader region (Atlantic hotspot volcanism). It has a pattern: intrusion → swarms → fissure opening → lava flows.
- 1949: fissure eruption with major cracking and deformation
- 1971 (Teneguía): classic basaltic eruption with coastal lava delta growth
- 2021 (Cumbre Vieja): long-duration eruption with large lava fields, ash/gas impacts, and persistent seismicity
Madeira volcanic province (why it belongs here)
Madeira is quieter today, but it is not “unrelated.” It belongs to the same broader hotspot-built province as the Canaries, and its cliffs and submarine debris slopes show a long history of volcanic growth followed by erosion and slope failure.
Why these islands are dangerous
- Lava flows: slow but unstoppable when they enter developed zones
- Ash and gas: aviation disruption + health impacts depending on wind direction
- Volcanic earthquakes: swarms can be intense, shallow, and long-lasting
- Flank collapses / landslides: the main tsunami mechanism in this system
- Coastal lava deltas: unstable new land that can fail suddenly

Frequently Asked Questions
Are the Canary Islands part of the Ring of Fire?
No. The Canary Islands are primarily hotspot volcanoes on the African Plate, not a subduction-arc system like the Ring of Fire.
Why do the Canary Islands have earthquake swarms?
Most local swarms are volcanic: magma intrudes as dikes, pressurizes reservoirs, and fractures rock as it migrates underground.
Can the Canary Islands generate tsunamis?
Yes. The main tsunami mechanism is large landslides or flank collapses (subaerial or submarine). Most scenarios are local-to-regional, but very large prehistoric collapses left Atlantic-scale debris deposits.
Which Canary island is most active right now?
On human timescales, La Palma and El Hierro are among the most recently active. Tenerife has very high consequence risk due to exposure even if eruptions are less frequent.
Is Madeira part of the same volcanic system?
Madeira belongs to the broader Canary–Madeira hotspot-built volcanic province. It is quieter historically, but it shares the same long-term hotspot construction context.
