This is the moment molten lava spews more than 30 metres into the air during a dramatic volcanic eruption.
Scientists who are monitoring the latest eruption in the 200-year-old Holuhraun lava field, near the Bardarbunga volcano in southeast Iceland, have been treated to quite a show since it began Sunday.
They say the eruption from a fissure just north of the rumbling volcano has not created any ash fall and the seismic activity decreased by almost half on Tuesday, with 300 earthquakes reported over a 12-hour period.
A white plume of steam and gas extends nearly three miles above sea level, and highly dangerous gas levels have been detected around the eruption site where rivers of fire are forming as lava gushes out of a mile-long crack in the ground.
Visitors are being told to equip themselves with gas masks and gas readers.
Thousands of earthquakes have rocked the region around Iceland's largest volcano for weeks amid fears that the airline industry would see a repeat of the 2010 ash cloud crisis. Iceland’s aviation alert level remains at orange – the second-highest level – because there is currently no ash cloud threat, although that could change, experts warn.
Close-up photos of the gaping fissure, volatile lava fountains and a billowing cloud of steam and gas reveal the raw beauty and brute force of volcanic activity. Photographer Einar Gudmann, 47, flew through windy weather and a sandstorm to reach the dangerous eruption site to take the images.
Raw beauty: Lava spews out of a mile-long fissure that slices through the Holuhraun lava field north of Bardarbunga, Iceland's largest volcano
The lava flowing from the fissure is known as pahoehoe lava, a Hawaiian term, and it is forming slabs on the surface
Incredible scene: Scientists say the temperature of the lava is about 1200C at the centre of a fissure near the rumbling volcano
Fountains of lava: Scientists are keeping a close watch on Bardarbunga, Iceland’s largest volcano, and the 200-year-old Holuhraun lava field
Air travel worries: Scientists say the eruption that began Sunday has not created any ash fall and the seismic activity decreased by almost half on Tuesday
Dramatic eruption: A white plume of steam and gas extends nearly three miles above sea level, but the aviation alert level has not been raised above orange
Photographer Einar Gudmann, from Akureyri, Iceland, battled windy weather and a sandstorm to shoot the scene from a plane 500 feet above the ground
Uncertain future: Scientists say they are monitoring the situation and the potential scenarios include additional eruptions that could cause flooding or an ash cloud

Highly dangerous gas levels have been reported at the eruption site, so scientists are urging visitors to be equipped with gas sensors and gas masks
