Iceland is famous for its stunning natural beauty, from waterfalls and glaciers to its most dynamic and awe-inspiring feature: volcanoes. Located on the Mid-Atlantic Ridge, Iceland straddles the boundary between the North American and Eurasian tectonic plates, making it one of the most volcanically active regions on the planet. With both dormant and active volcanoes, Iceland’s landscape is constantly shaped by volcanic activity, offering visitors a unique opportunity to witness this powerful force of nature.
In this comprehensive guide, we’ll dive into everything you need to know about volcanoes in Iceland—from its volcanic history to the most famous eruptions, as well as practical tips for travelers wanting to experience the island’s volcanic landscapes firsthand.
Why Is Iceland Volcanic?
The answer to the question, “Is Iceland a volcanic island?” lies in its unique geological location. Iceland sits directly on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are slowly pulling apart. This divergent boundary allows magma from the Earth’s mantle to rise to the surface, creating frequent volcanic eruptions and geothermal activity.
This geological positioning makes Iceland one of the few places in the world where you can physically see tectonic plates diverging, such as in Þingvellir National Park, where the gap between the plates is visible on land.
How Many Volcanoes Does Iceland Have?
Iceland has approximately 130 volcanoes, many of which are still active. Of these, about 30 systems are considered to be volcanically active, meaning they have erupted at least once in the last few thousand years. Iceland is home to both shield volcanoes and stratovolcanoes, each contributing to the island’s rugged and dramatic topography.
For those asking, “How many volcanoes are in Iceland?”, the country has a large number of volcanic systems, some of which are constantly monitored due to their potential for eruptions.
Famous Icelandic Volcanoes
While Iceland has numerous volcanoes, a few have gained particular notoriety due to their significant eruptions or their proximity to popular tourist areas. Here are some of the most well-known volcanoes in Iceland:
Hekla
Known as the “Gateway to Hell” in the Middle Ages, Hekla is one of the most famous and active volcanoes in Iceland. Located in southern Iceland, Hekla has erupted more than 20 times in recorded history, with the most recent eruption occurring in 2000. Its history of large explosive eruptions has earned it a fearsome reputation, but it also draws adventurers keen to hike its slopes and experience its stark beauty.
Eyjafjallajökull
Perhaps the most famous Icelandic volcano in recent history, Eyjafjallajökull made global headlines in 2010 when it erupted, spewing ash high into the atmosphere and causing widespread disruption to air travel across Europe. While the eruption itself was moderate in size, the ash cloud had significant impacts, reminding the world of Iceland’s volcanic power.
Katla
Beneath the Mýrdalsjökull glacier lies Katla, one of Iceland’s most powerful volcanoes. Known for its large, explosive eruptions, Katla has erupted at least 20 times since Iceland was settled over a thousand years ago. Although it has been relatively quiet for a century, Katla remains closely monitored, as another major eruption could cause serious flooding due to melting glacial ice.
Askja
Located in the remote highlands, Askja is a massive caldera formed by volcanic activity. The surrounding area, known for its lunar-like landscapes, was used by NASA to train astronauts for the Apollo missions. Askja’s most famous eruption occurred in 1875, and the resulting ashfall caused widespread devastation to farms in the region.
Volcanic Eruptions in Iceland: How Often Do They Occur?
Due to its tectonic setting, volcanic eruptions in Iceland are relatively common. On average, a volcanic eruption occurs every 4-5 years. While some eruptions are small and localized, others, like the 2010 Eyjafjallajökull eruption, can have far-reaching effects. One of the key questions often asked is, “How often do volcanoes erupt in Iceland?”, and the answer is that volcanic activity in the region is frequent and part of the natural landscape.
What Are the Impacts of Iceland’s Volcanic Activity?
The frequent volcanic activity has both positive and negative impacts on the country. On the positive side, the geothermal energy generated by volcanic activity provides a clean and renewable source of power for much of Iceland. Many of the country’s famous hot springs, such as the Blue Lagoon, owe their existence to volcanic geothermal energy.
However, volcanic eruptions can also be destructive. Large eruptions have historically caused significant damage to farmland and infrastructure, particularly when glacial floods (known as jökulhlaups) are triggered by the heat from volcanic activity. For example, when Grímsvötn erupted in 1996, the resulting flood washed away large sections of the Ring Road, the main highway that circles the island.
Experiencing Volcanoes in Iceland
If you’re visiting Iceland, experiencing the volcanic landscape firsthand is a must. Several volcanoes are accessible to hikers, while others can be observed from a safe distance. Here are a few ways to explore Iceland’s volcanic wonders:
Hiking to Volcanoes
Hiking is one of the best ways to experience Iceland’s volcanoes. Trails like those leading up Hekla or into the Askja caldera offer visitors an up-close look at these geological marvels. Make sure to check for weather conditions and any possible volcanic activity before embarking on these hikes, as conditions can change rapidly.
Volcanic Craters and Lava Fields
If hiking up a volcano isn’t your thing, you can explore Iceland’s many volcanic craters and lava fields. Laki is one of the most famous volcanic fissures in the country, responsible for a devastating eruption in 1783 that changed the course of Icelandic history. The Dimmuborgir lava fields near Lake Mývatn are another popular destination, with twisted rock formations that look like something out of a fantasy novel.
Volcano Tours
For a guided experience, consider joining a volcano tour. Several companies offer tours that take you to some of Iceland’s most iconic volcanoes, including helicopter tours that provide an aerial view of volcanic landscapes.
Frequently Asked Questions
How many volcanoes are there on Iceland?
There are approximately 130 volcanoes in Iceland, with about 30 volcanic systems considered active.
Is the volcano in Iceland still erupting in 2024?
As of now, there is no significant volcanic eruption in Iceland in 2024, but volcanic activity is constantly monitored.
When was the last eruption in Iceland?
The last significant eruption in Iceland occurred in 2022, at the Fagradalsfjall volcano on the Reykjanes Peninsula.
How serious is the volcano in Iceland?
Volcanic eruptions in Iceland can range from mild to severe. While many eruptions are localized, larger eruptions, like those of Eyjafjallajökull or Katla, can have serious consequences, including flooding and ash clouds.
Final Thoughts on Volcanoes in Iceland
Visiting Iceland’s volcanoes is a once-in-a-lifetime experience that combines the thrill of adventure with the wonder of natural beauty. Whether you’re hiking up the slopes of a dormant giant or marveling at the steaming geothermal fields created by volcanic activity, Iceland’s volcanic landscape will leave you in awe.
