Bárðarbunga Expedition

The views of the volcano from the plane were impressive to say the least. That was on the Saturday, the day of our arrival. It was on the Sunday, whilst enjoying lunch with some Spanish red wine that the real adventure began. It was an unexpected but most welcome twist to our journey that we will remember for the rest of our days.


At around 2pm we received a call from the Civil Protection Agency informing us that access to “point zero” was now permitted. We were not expecting this. In fact when we got the call we were planning our return trip to Reykjavik. Suffice to say we quickly finished eating and ran to the hotel to collect our belongings.

Time was of the essence, so we headed straight for the meeting point at Myvatn to find our contact Sindri, who would take us to the volcano. Sindri, a local expert driver-guide was as excited as we were. It was the first time he had the opportunity to experience a volcano at such close quarters.After checking all of our equipment, including dangerous gas sensors we jumped into the Super Jeep and headed off to the “giant in flames”.


The unpredictable nature and potentially devastating effects of volcanoes is something not to be taken lightly, and with the eruption of 2010 still fresh in our minds we approached the eruption site with no little amount of trepidation and fear. However, our relentless thirst for travel, our fascination of the volcano plus our commitment to report on the events helped to give us the impetus we needed to get there.


Less than an hour later we were in Moðrudalur, the last inhabited settlement before entering the maze of tracks that lead to the volcano. The possibility of a sub-glacial eruption flooding the valley that offered the most direct route, we were forced to take a diversion  through winding roads and lava fields from the east to the shelter of Askja. From here we would follow a new path that would lead us to Þorvalstindur and the eruption area.


The numerous police checks combined with the slow arduous going on the barely drivable tracks in this bleak arid landscape merely served to compound our frustration. Night was approaching and there was still another 35km to go. The glow of the clouds in the distant lent an apocalyptic feel to the proceedings. Fear, respect, excitement, impatience, apprehension, joy, curiosity – our team were experiencing a cocktail of emotions that somehow managed to unite us more than ever.


We finally arrived at Askja. We stopped at the hut there for a few minutes before the countdown could begin. Our journey to the gates of hell was almost over. Sindri accelerated as if possessed by demons as the engine of the 4X4 roared into action.Suddenly it was there. Expelling magma and smoke with a violent force that coloured the sky with dark foreboding shades of grey.


With a bright red dot on the horizon forming a strange almost surreal sunset that illuminated a seemingly infinite expanse of black sand, our indefatigable horse walked on. A glacier and a dark mountain completed this otherworldly landscape, and I felt like I was marching into a battle at the end of the world. My very own Ragnarrök.

Then it hit me. What if the activity at Bárðarbunga suddenly increases. What if a dreaded subglacial eruption floods the entire area that surrounds us? I glanced nervously at Sindri, and he sensed my unease. I ordered him to stop the jeep. We could feel the ground beneath us shaking. I asked him if he was sure we were doing the right thing. Without hesitation and displaying a bravado so typical of a Viking warrior he replied that we were. We took advantage of this brief pause to take pictures and videos just as it was getting dark.


Our desire to be as close as possible to the eruption spurred us on. We set off again, and 10 minutes later we were almost there. The darkness had made the glowing embers of the lava almost indistinguishable from the red lights of the few vehicles that were already there.


Finally there it was. The Volcano. It would be futile for me to even attempt to explain how I felt. There are simply no words. The excitement just flowed through my body and I could feel tears trickling down my cheeks. Pictures and videos can only go some way to describing the sensation of witnessing a volcano eruption. There is nothing that can truly depict what we felt. All I can say to you,  friends, readers and travellers is to believe me when I say that there is nothing more powerful or humbling than the unrestrained forces of nature.

Holuhraun Eruption Tour in Iceland - Bárðarbunga Eruption Sightseeing Flight

10:25 Iceland - LATEST NEWS


There was a nervous atmosphere as we travelled in silence to Mývatn. The Iceland24 team had just been informed that, for security reasons the volcanic eruption site around Holahraun was inaccessible by jeep.



After waiting almost a week to get a permit from the Icelandic authorities it was disappointing to discover we could not get there by car. However we were determined not to miss the opportunity to be in the “eye of the storm”.


The only way to reach the site of the eruption has been to take a small plane and fly over it. From this vantage point one gets to truly appreciate the real size of the fissure eruption that the whole world has been keeping an eye on. After a long day, we can finally give you a first hand account of it .


To experience the lava fountains spewing magma more than 100 metres into the air next to the largest glacier in Europe is a difficult to feeling to describe. It was almost like witnessing Earth “giving birth”. This felt particularly true when we saw the vivid colours of the so called “curtain of fire”.




The smouldering lava field was moving at about 40 metres per hour, engulfing everything in its path. Latest developments indicate that there is an explosive encounter between the lava and the Jökulsá glacial river that flows from the glacial tongue of Dyngjujökull. 


Volcanic activity in the area has remained stable over the past few days, although seismic activity has decreased slightly.



Islandia24 will continue to report from the site. Our commitment is not only to our followers but also to discovering the truth behind the stories, leaving us no choice but to see the eruption for ourselves.

Bárðarbunga: The situation is considered stable

The seismic activity in Bárðarbunga is still strong. Last night at 01:26 there was an earthquake of M5,7 which make it the biggest one since the events started on Saturday 16. of August.

Just before noon today there was an earthquake (M4,6) under the edge of Dyngjujökull. The earthquake was felt as far away as Akureyri. The Civil Protection department is following the events closely, but the situation is considered stable.


Ak­ur­eyri wobbles in eart­hqua­ke

An eart­hqua­ke of the magnitu­de 4.6 was mea­sured und­er the edge of Dyngju­jök­ull at 11:56 am today at 8 km depth. The eart­hqua­ke was felt by some resi­dents as far as the town of Ak­ur­eyri, and it is the lar­gest since one of the magnitu­de 5.7 was mea­sured in the nort­hern/​nort­hwestern part of Bárðarbunga at 01:26 last night.

The Advisory bo­ard held a meet­ing this morn­ing to discuss the Bárðarbunga situati­on. Follow­ing the meet­ing the same three scen­ari­os as predicted yester­day are still consi­d­ered most likely.

The follow­ing po­ints were the conclusi­on of the bo­ards meet­ing.In­ten­se seismicity cont­inu­es with over 500 events recor­ded since midnight.

Seismicity cont­inu­es to migra­te nort­hw­ard and is now concentra­ted on the 10 km long tip of the dike ext­end­ing 5 km beyond the edge of the Dyngju­jök­ull glacier.The dyke bene­ath Dyngju­jök­ull is now thoug­ht to be close to 40 km long. Modell­ingof GPS data indica­tes that about 50 milli­on cu­bic meters of magma have added to the volume in the last 24 hours.

Fur­t­hermore th­ere are no indicati­ons that the in­tensity of the acti­vity decl­in­ing.

Expert: Likely no eruption yet

The IMO has changed the aviation color code from red back to orange. No visible sign of eruption but seismic activity still ongoing.

Geoscientists in Iceland seem to be of differing opinion regarding the small eruption that is believed to have taken place today. The Iceland Met Office said today that an eruption had likely taken place, but a professor of geophysics at University of Iceland sees no signs of an eruption.

A group of scientists surveyed the glacier today from the air, aboard a surveillance plane from the Icelandic Coastguard. After the flight, Magnus Tumi Gudmundsson, professor of geophysics at University of Iceland, was interviewed at RUV.


„The most likely scenario is that an eruption has not begun. This morning we saw a large increase in seismic activity and tremors, so it was perfectly rational to assume that an eruption had begun. A subglacial eruption melts the ice and causes floods. We surveyed the glacier for three hours today. I can of course not assert that nothing has happened, but it is clear that there are no signs of abnormal melting or other signs that normally appear during a subglacial eruption. It is therefore likely that the magma has not reached the surface yet - regardless of what will happen later in this process, because this is a fairly large event and those who delay to give timely warnings can carry a large responsibility.

Therefore, it was considered proper to be careful today but when more information comes in, the most likely conclusion is that an eruption has not begun, whatever happens later in this event,“ said Magnus this evening on RUV television newscast.


„The most current information I have is that the latest GPS deformation measurement shows that the dyke intrusion is getting wider and getting longer. That means that magma is still moving. Whether that results in an eruption or not, only time can tell. If we look at the Krafla eruptions, which are the most similar eruptions, we had a lot of dyke intrusions there at the beginning, but much smaller volcanic activity. We don´t know if this activity will show a similar pattern, but we have to be prepared. This run-up is positive in a way, because we have had time to prepare. There are no tourists in the area, so it´s positive that the process has not been more rapid. And of course, we all hope that this will end without an eruption and the ensuing damage.

“The dyke intrusion has been forming over the last few days. It is now believed to be around 25 km. long, and about 0,2 - 0,3 cubic kilometers of magma is thought to have entered the intrusion from a magma chamber beneath the Bardarbunga caldera. The intrusion has been propagating towards the north: it´s lenght seems to have increased by several kilometers just today.


At this stage measurements taken are based on a small event. The Jökulsárgljúfur canyon has been closed and evacuation of tourists in that area and around Dettifoss waterfall has started. The situation at this stage does not call for evacuation of habitants in Kelduhverfi, Öxarfjördur and Núpasveit. People in those areas are encouraged to watch news closely and have their mobiles switched on at all times.

Small eruption believed to have started

The Icelandic Met Office says a small subglacial eruption started today beneath the Dyngjujokull outlet glacier, near the Bardarbunga caldera. Scientists aboard a surveillance airplane above the glacier see no signs of an eruption yet. All flight traffic has however been banned near the volcano.

Kristin Jonsdottir, geophysicist at the Icelandic Met Office says that this morning, increased seismic activity and increased tremor was observed around the Bardarbunga caldera, especially in a 25 km. long dyke intrusion north and east of the caldera, near the edge of the Dyngjujokull outlet glacier. 


Shortly after 2 PM GMT, the Met Office declared an aviation alert for a large area around Bardarbunga and said a small eruption was believed to have started under the glacier. No signs of glacial flood has been observed and scientists in a surveillance airplane above the glacier see no sign on the surface of the glacier. Even so, the measurements indicated a small eruption under the glacier and it is now believed that it was small enough, not to cause significant melting of glacial ice. A larger eruption can not be ruled out, according to the Met Office. 

The dyke intrusion has been forming over the last few days. It is now believed to be around 25 km. long, and about 0,2 - 0,3 cubic kilometers of magma is thought to have entered the intrusion from a magma chamber beneath the Bardarbunga caldera. 

At this stage measurements taken are based on a small event. The Jökulsárgljúfur canyon has been closed and evacuation of tourists in that area and around Dettifoss waterfall has started.
