In the tonight news on Rúv about this area, Páll Einarsson geologist at University of Iceland says in the news on Rúv that there is a good reason to worry about this area. As it is one of the most active one in Iceland, but it is directly above the mantle plume under Iceland. Páll Einarsson also says in the news on Rúv that before the eruption in the year 1996, that took place in a volcanic ridge now named Gjálp there was a increase in earthquake activity in Kistufell field.
The large central volcano of Bárdarbunga lies beneath the NW part of the Vatnajökull icecap, NW of Grímsvötn volcano, and contains a subglacial 700-m-deep caldera. Related fissure systems include the Veidivötn and Trollagigar fissures, which extend about 100 km SW to near Torfajökull volcano and 50 km NE to near Askja volcano, respectively. Voluminous fissure eruptions, including one at Thjorsarhraun, which produced the largest known Holocene lava flow on Earth with a volume of more than 21 cu km, have occurred throughout the Holocene into historical time from the Veidivötn fissure system. The last major eruption of Veidivötn, in 1477, also produced a large tephra deposit. The subglacial Loki-Fögrufjöll volcanic system located SW of Bárdarbunga volcano is also part of the Bárdarbunga volcanic system and contains two subglacial ridges extending from the largely subglacial Hamarinn central volcano; the Loki ridge trends to the NE and the Fögrufjöll ridge to the SW. Jökulhlaups (glacier-outburst floods) from eruptions at Bárdarbunga potentially affect drainages in all directions.
There is every reason to have a reservation No scopes on most active earthquake areas. Seismicity in northwestern Vatnajökull is increasing and every reason to have a reservation, said Paul Einarsson, Professor of Geophysics. However, missing an earthquake measuring the area, in order to keep with. In recent days, the cycle earth quake measured near Kistufell and Bárðarbunga the northwest side glacier, this is an active area, and no wonder - there is the middle of the mantle plume that comes to the country. "This brings together several systems. Bard's biggest Bung system which includes Veiðivötn, water waves and lies far north and west Dyngjuháls caldera. Then of course Grim water system that lies a little further east. " Paul says Bard Bung themselves to be most active now and sprungusveimur from north-east of it. On this site seismicity has been sustained since measurements began. it is however most active now Bárðarbunga self and sprungusveimur to NA from her. there has been persistent seismicity since measurements began, and has sometimes been more like Always ahead of the eruption was in 1996. However, it is difficult to say whether the quake are now caused by the volcanic eruption, or whether the region is to apply a rate cut. "That we need better measurements. For example, it is difficult to measure the depth of earthquakes in these areas because it lacks measured in the net in the middle of the country, as a crustal because much of the area is covered with glaciers. There is no doubt that skjálftavirknin there is slowly growing, and that seismicity the last few days, it is a sign of it. There is every reason to have a reservation. This is the most active areas of the country if we look at the whole country together. "
The system erupted over an 8 month period during 1783-1784 from the Laki fissure and the adjoining Grímsvötn volcano, pouring out an estimated 14 km3 (3.4 cu mi) of basalt lava and clouds of poisonous hydrofluoric acid/sulfur-dioxide compounds that killed over 50% of Iceland's livestock population, leading to famine which killed approximately 25% of the population. The Laki eruption and its aftermath has been estimated to have killed over six million people globally, making it the deadliest volcanic eruption in historical times. The drop in temperatures, due to the sulfuric dioxide gases spewed into the northern hemisphere, caused crop failures in Europe, droughts in India, and Japan's worst famine.An estimated 120 million tons of sulfur dioxide was emitted, about three times the total annual European industrial output in 2006, and equivalent to a 1991 Mount Pinatubo eruption every three days.

Well, here we are… two bruisers and the associated hangers on that are ready to rumble, itching for a fight. (Bárðarbunga, Grimsvötn, Hamarrin, that dis-interested daughter volcano south of Grimsvötn that I am not even going to try and transliterate, and Askja prancing around up in the corner screaming “me too!!”)
“It is indisputable that the seismic activity is growing steadily in the area—the series of earthquakes over the past few days is an indicator of that. There is full reason to be on the alert. This is one of the most active areas in the country,” he iterated.
