Krafla Volcano, located in the Mývatn region of North Iceland, is one of Iceland’s most active and well-known volcanoes. Its 10 km-wide caldera, formed about 100,000 years ago, is part of the active volcanic zone along the Mid-Atlantic Ridge. Krafla is famous for its frequent eruptions, geothermal activity, and dramatic lava fields. Visitors to the area are captivated by its rugged landscape, which features craters, steaming vents, bubbling mud pots, and lava fields. The last major eruptions, known as the "Krafla Fires," lasted from 1975 to 1984, leaving behind a landscape that looks otherworldly and is still warm in places.

History of Krafla Volcano
The history of Krafla is one of frequent volcanic activity and eruptions, with the most significant events occurring in the 18th and 20th centuries. Krafla has erupted at least 29 times since Iceland was settled, but its most famous eruptions are part of the "Krafla Fires" from 1975 to 1984. During this period, the ground fissured and magma spewed from cracks, leading to the formation of new lava fields that cover a large portion of the surrounding area. This event significantly altered the landscape, creating dramatic lava flows that visitors see today.
Major Eruptions at Krafla
-
1724–1729: The Myvatnseldar Eruptions — created the massive Víti crater.
-
1975–1984: Krafla Fires — a series of eruptions and geothermal activity that lasted nearly a decade, covering the area in fresh lava.
What Caused the Krafla Volcano?
The volcanic activity at Krafla is due to its location on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are pulling apart. Magma from deep within the Earth rises through these fissures, creating both volcanic eruptions and geothermal activity. The magma chamber beneath Krafla is responsible for the region’s frequent eruptions and geothermal phenomena.
Geology and Surroundings
Krafla is located in a highly active geothermal region, and its landscape reflects the dynamic forces of the Earth. The volcano’s surroundings include vast lava fields, fissures, craters, and hot springs. The volcanic activity of Krafla has been pivotal in shaping the surrounding terrain, and its proximity to Lake Mývatn adds to the area's ecological and geological significance. The nearby Leirhnjúkur lava field is a striking reminder of the Krafla Fires, with black, jagged lava stretching as far as the eye can see.
The Víti Crater is another important feature in the Krafla area. Formed during an eruption in 1724, Víti contains a bright blue geothermal lake that contrasts beautifully with the surrounding volcanic rock. It's one of the unique crater lakes in Iceland similar to the better known Kerið.
Krafla Today
Today, Krafla is still an active volcanic area, with frequent geothermal activity such as fumaroles, bubbling mud pots, and warm rocks. While there hasn’t been a significant eruption since the 1980s, the area remains geothermally active, making it a unique location for visitors to experience volcanic landscapes up close. The Krafla Power Station harnesses the geothermal energy of the area and is open to visitors who want to learn more about Iceland’s use of renewable energy.
Though you can’t currently see flowing lava, the geothermal landscape, especially at Leirhnjúkur, still feels alive, with steam rising from cracks and vents in the earth.
Tips for Visiting Krafla
Visiting Krafla offers the chance to explore an otherworldly volcanic landscape. The area is open year-round, but access can be limited in the winter due to snow. It’s advisable to dress warmly and wear sturdy footwear, as the terrain can be rugged.
