Loki-Fögrufjöll, Subglacial volcano in Vatnajökull National Park, Iceland
Loki-Fögrufjöll is a volcano beneath the Vatnajökull glacier, rising about 1,573 meters, with multiple magma chambers and fissure systems hidden under the ice. The mountain displays the typical features of a subglacial volcano, with various volcanic structures concealed beneath the frozen surface.
A major volcanic eruption with ash fall occurred in 1910, marking an important event in the region. Since then, several other periods of activity have been recorded in 1986, 1991, and 2011, showing that this volcano remains active today.
The name comes from Norse mythology and shows how these ancient stories are woven into Iceland's geography. Many Icelandic places carry such names, linking the landscape to the country's heritage.
Visiting this site requires specialized equipment and professional guides, as it is located beneath the glacier in a geologically active area. Seismic activity is frequent in this region, so preparation with experienced guides is essential.
The 2011 eruption triggered an unprecedented glacial flood that dramatically raised water levels in a nearby lake. This rare combination of volcanic activity and glacier effects shows the extreme forces working beneath Iceland's surface.
