Bardarbunga Volcano in Vatnajokull glacier
We arrange training grounds for professional athletes or amateurs
Extreme Iceland offers many opportunities for athletes to coach in Iceland. Due to its incredible nature, such as geothermal water, glaciers and mountains, Iceland provides a fantastic environment for you to improve your sport skills or prepare for a particular event.
Bárðarbunga, is a stratovolcano located under the Vatnajökull glacier in Iceland. It rises to 2,009 metres (6,591 ft) above sea level, making it the second highest mountain in Iceland and part of the largest volcanic system, considered to be close to 200 kilometres (120 mi) long and up to 25 kilometres (16 mi) wide.
In August 2014, an earthquake swarm occurred, with at least 1,155 earthquakes recorded on August 16 and 17, with magnitudes up to 4.5 on the moment magnitude scale.
Extreme Iceland offers tours to the locations of the eruption where and when it occurs. The tours are under the supervision of experienced mountain guides and Geologists. It doesn't matter where in Iceland the eruption may happen or when, we will take you to the spectacle of raw power erupting from the ground.
Feel free to book in advance for those trips and you'll be notified by our staff when next eruption happens.

Bárðarbunga is a subglacial stratovolcano located under the ice cap of Vatnajökull glacier, rising to 2,009 metres (6,591 ft) above sea level, making it the second highest mountain in Iceland, about 101 metres (331 ft) lower than Hvannadalshnjúkur.
The Bárðarbunga caldera is about 70 square kilometres, up to 10 kilometres (6 mi) wide and about 700 metres (2,300 ft) deep. The surrounding edges rise up to 1850 metres but the base is on average close to 1100 metres. The volcano is covered in ice, hiding the glacier-filled crater.
Bárðarbunga was a little-known volcano in Iceland due to its remote location and infrequent eruptions. Many tephra layers originally thought to belong to other volcanoes have in the recent studies proved to be from Bárðarbunga. The Gjálp fissure eruption in 1996 revealed that an interaction may exist between Bárðarbunga and Grímsvötn. A strong earthquake in Bárðarbunga, about 5 on the Richter scale, is believed to have started the eruption in Gjálp.
Sustained seismic activity has been occurring in Bárðarbunga for some years without an eruption, thus the volcano is still active.
There is frequent volcanic activity outside the glacier to the southwest in the highlands between Vatnajökull and Mýrdalsjökull, also to the northeast toward Dyngjufjöll.
In historic times there have been large eruptions every 250–600 years. Þjórsá Lava is the largest holocene lava flow on the earth, it originated from Bárðarbunga about 8500 years ago, with a total volume of more than 21 cubic kilometers with some estimates saying as high as 30 cubic kilometers; it covers approximately 950 square kilometers. The largest eruption from Bárðarbunga had a VEI of 6, many smaller-sized eruptions have been recorded in the past 10000 years.
Many large prehistoric eruptions have occurred southwest of the glacier, of which two after the settlement of Iceland: the Vatnaöldur eruption about 870 and the Veiðivötn eruption in 1480. Both were very large eruptions that would have major effects on life in Iceland and neighboring countries were they to recur in modern times.
Smaller eruptions are frequent northeast of Bárðarbunga in an ice-free area called Dyngjuháls. Such an eruption last occurred in 1862-4.
Studies of tephra layers have shown that a number of eruptions have occurred beneath the glacier itself, probably in the northeast of the crater or in Bárðarbunga. These eruptions appear to follow a cycle: there were several eruptions in the glacier between 1701–40 and since 1780. There hasn't been an eruption in the glacier or the system since 1864. Frequent earthquakes in Bárðarbunga indicate that the volcano will erupt sooner rather than later.
In September 2010, an earthquake swarm occurred near Bárðarbunga, with over 30 earthquakes recorded on 26 September, the largest quakes measuring 3.5 and 3.7 on the moment magnitude scale.
In August 2014, another earthquake swarm occurred, with at least 1,155 earthquakes recorded on August 16 and 17, of which the largest had a magnitude of around 4.5 on the moment magnitude scale.
Dangers from eruptions
Large volcanic fissure eruptions occur every 500–800 years in Iceland. They often occur in the Veiðivötn area, south-west of the Bárðarbunga central volcano. Such an eruption would endanger many of Iceland's hydroelectric power plants, as each eruption changes the landscape dramatically. Tephra from a large eruption from the Bárðarbunga volcanic system could affect flight traffic and temperature in northern parts of the world.

An eruption is ongoing in the highlands of Iceland, just north of Vatnajokull glacier. We offer sightseeing flights over the eruption area, as long as the eruption lasts. Don't miss this unique opportunity to see an eruption and the hot flowing lava.
