25 Interesting Facts about Iceland Volcanoes

Iceland is renowned for its dramatic volcanic landscapes, home to numerous volcanoes that have shaped the island’s terrain and captivated the world’s imagination. The country’s volcanic activity is a result of its location on the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates meet, creating a volatile geological setting.

One of Iceland’s most famous volcanoes is Eyjafjallajökull, known for its 2010 eruption that disrupted air travel across Europe. This explosive eruption spewed ash and volcanic gases into the atmosphere, causing widespread flight cancellations and illustrating the significant impact volcanic activity can have on global infrastructure.

Another notable volcano is Katla, located near Eyjafjallajökull. Katla is known for its historical eruptions, occurring roughly every 40 to 80 years on average. Its eruptions often produce massive amounts of ash, posing potential risks to air travel and regional environments.

Hekla is among Iceland’s most active and historically famous volcanoes. Often referred to as the “Gateway to Hell” due to its frequent eruptions, Hekla’s explosive activity has been documented since the Middle Ages. Despite its reputation, Hekla has also experienced dormant periods, contributing to uncertainties about its next eruption.

Iceland’s volcanic activity isn’t solely about explosive eruptions. The country is home to unique volcanic features like lava fields, volcanic craters, and geothermal areas such as the Krafla volcanic system. This system showcases the diverse nature of volcanic activity, including lava flows, geysers, and hot springs, attracting visitors seeking to witness these geological marvels.

The ongoing volcanic activity in Iceland serves as a reminder of the dynamic forces shaping our planet. While it presents challenges, such as potential disruptions to air travel and local communities, it also offers a profound opportunity to study and appreciate the raw power and geological wonders of volcanic landscapes.

Do you want to know more about Iceland volcanoes? Let’s take a look at these 25 interesting facts about Iceland volcanoes.

  1. Geological Hotspot: Iceland sits atop the Mid-Atlantic Ridge, a tectonic boundary where the Eurasian and North American plates diverge, resulting in intense volcanic activity.
  2. Volcanic Count: There are approximately 130 volcanic mountains in Iceland, with around 30 of them having erupted in the past two centuries.
  3. Eyjafjallajökull Eruption: The 2010 eruption of Eyjafjallajökull caused massive disruption to European air travel due to the ash clouds that drifted across airspace.
  4. Katla’s Activity: Katla, situated near Eyjafjallajökull, is one of Iceland’s most active volcanoes, erupting on average every 40 to 80 years.
  5. Hekla’s Legacy: Hekla, often called the “Gateway to Hell,” has erupted over 20 times since the Middle Ages, with some eruptions lasting for years.
  6. Grímsvötn Eruptions: Grímsvötn, located beneath the Vatnajökull ice cap, is one of Iceland’s most active volcanoes, erupting roughly every 5–10 years.
  7. Laki Eruption: The 1783 Laki eruption, lasting eight months, produced massive lava flows and sulfur dioxide emissions, leading to environmental and agricultural devastation.
  8. Surtsey Formation: Surtsey, an island formed by a submarine volcanic eruption in 1963–1967, remains a significant site for studying volcanic succession and ecosystem development.
  9. Subglacial Volcanoes: Several Icelandic volcanoes, such as Katla and Grímsvötn, are subglacial, leading to potentially explosive interactions between volcanic activity and ice.
  10. Vatnajökull National Park: Encompassing multiple volcanoes, including Öræfajökull and Bárðarbunga, the park showcases diverse volcanic landscapes and glacial formations.
  11. Volcanic Hazards: Iceland’s volcanic activity poses risks like ash clouds affecting aviation, jökulhlaups (glacial outburst floods), and lahars (mudflows) due to glacial melting during eruptions.
  12. Fissure Eruptions: Many Icelandic eruptions occur along fissures, resulting in extensive lava flows, such as those seen during the 2014–2015 Holuhraun eruption.
  13. Thermal Energy: Geothermal activity resulting from volcanic heat powers much of Iceland’s energy needs, providing heating and electricity to homes and industries.
  14. Volcano Monitoring: Iceland has a robust volcano monitoring system, utilizing seismic networks and satellite technology to monitor volcanic activity and forecast potential eruptions.
  15. Pele’s Hair and Tears: During volcanic eruptions, fine glassy threads called Pele’s hair and droplets known as Pele’s tears form due to lava fountaining.
  16. Volcanic Tourist Attractions: Iceland’s volcanoes, including the Askja Caldera and Krafla volcanic system, draw tourists seeking to witness geothermal areas, craters, and lava fields.
  17. Eldfell Eruption: The 1973 Eldfell eruption on Heimaey Island led to the evacuation of the town and the creation of a new harbor through lava diversion.
  18. Icelandic Folklore: Volcanoes are deeply embedded in Icelandic folklore, with tales of volcanic spirits and creatures inhabiting these fiery landscapes.
  19. Lava Tubes: Iceland’s volcanic activity has formed extensive lava tubes, such as those found in Víðgelmir, offering unique exploration opportunities.
  20. Global Impact: The ash and aerosols from Icelandic eruptions can influence global weather patterns and sunsets due to their sulfuric acid content.
  21. Submarine Volcanoes: Iceland’s volcanic activity extends underwater, with submarine eruptions forming new volcanic islands or altering the seabed landscape.
  22. Post-Eruption Ecology: After volcanic eruptions, life rapidly returns to affected areas, with lichens and mosses colonizing barren lava fields, kickstarting ecological succession.
  23. Icelandic Naming Conventions: Many Icelandic volcanoes are named based on their physical characteristics or nearby landmarks, contributing to the island’s rich geography.
  24. Tuya Formation: Some Icelandic volcanoes, like Herðubreið, exhibit unique flat-topped tuya formations resulting from volcanic eruptions under ice.
  25. Ongoing Research: Iceland’s volcanic landscape continues to be a hotspot for scientific research, studying volcanic processes, geothermal energy, and environmental impacts.

Iceland’s volcanic tapestry weaves a tale of fiery landscapes, geological wonder, and natural beauty that captivates both scientists and adventurers alike. From the explosive power of Eyjafjallajökull to the brooding might of Katla and Hekla, these volcanoes etch their stories across Iceland’s terrain. They stand not just as geographic landmarks but as windows into the Earth’s inner workings, revealing the raw forces that shape our planet.

Amidst the risks they pose, these volcanoes also offer unique insights, providing sustainable geothermal energy and nurturing ecosystems that emerge from their fiery aftermath. Iceland’s volcanoes serve as a reminder of nature’s awe-inspiring power, inviting exploration and study while enriching the tapestry of this island nation’s geological legacy.
