Considerably strong earthquakes hit Bárðarbunga volcano in Vatnajökull glacier yesterday evening, of magnitude 4.8 at 8:20 pm and of magnitude 5.4 at 9:34 pm.
Volcanologist Ármann Höskuldsson told RÚV yesterday that if the eruption in Holuhraun would stop then another eruption would occur in the same area shortly afterwards.
Seismic activity is continuing in the eruption area at Bárðarbunga and Holuhraun with about 50 earthquakes occurring between midnight and 6:45 am this morning.
Photographer Bernard Meric has been at the eruption site and the areas where the lava is flowing into the river Jökulsá á Fjöllum over the last few days and took the following images.
The Department of Civil Protection has advised all people in the village of Kópasker, Northeast Iceland, and surrounding areas to stay indoors, close the windows and turn up the radiators due to high levels of sulfur dioxide pollution from the eruption.
The largest earthquakes at Bárðarbunga last night measured magnitude 3.6 at 12:11 am, magnitude 3.7 at 12:14 am and magnitude 3.8 at 2:27 am. There have been no major changes in seismic activity, according to the latest update on the website of the Icelandic Met Office.
Sulfur dioxide (SO2) pollution from the eruption in Holuhraun spread to Northeast Iceland yesterday.
The eruption seems to be concentrated at the middle crater on the fissure at Holuhraun, but the ice on Bárðarbunga crater is still lowering, indicating that some changes are occurring.
New land is forming in Holuhraun and its vicinity. The biggest craters are rising higher up from the ground and a new lagoon and a waterfall could form when the lagoon builds a dam in Jökulsá glacial river.
One resident in Reyðarfjörður, East Iceland, described the sulfur dioxide pollution level as like standing behind a truck and inhaling the fumes.
The Icelandic Met Office has issued a new warning due to high concentration of sulfur dioxide (SO2) from the Holuhraun eruption. Scientists flying over the Bárðarbunga area yesterday reported no new changes in the surface yet assume that the caldera is continuing to subside. Farmers are rounding...
A satellite photo from NASA taken at noon yesterday shows the plume from the eruption in Holuhraun very clearly. The photo was published on the University of Iceland’s Institute of Earth Sciences’ Facebook page.
Approximately 30 earthquakes were picked up by sensors in and around Bárðarbunga volcano and the Holuhraun eruption since midnight. All of them were minor. The Icelandic Met Office has forecast air pollution for the East Fjords today.
Sulfur dioxide (SO2) levels in Reyðarfjörður, East Iceland, were ten times lower, or 240 μg/m3, this morning than when they peaked at 2,550μg/m3 at 2 pm yesterday.
The sulfur dioxide (SO2) levels in Reyðarfjörður, East Iceland, yesterday were more than four times the record levels detected in the town on Saturday. As reported, the pollution, caused by the Holuhraun eruption, measured 2550μg/m3 at its peak yesterday.
The smell of sulfur dioxide from the Holuhraun eruption has been detected on the west coast of Norway, according to public broadcaster NRK.
Scientists believe that the new lava from the Holuhraun eruption could block glacial river Jökulsá á Fjöllum, as it is now approaching an area where the river flows through old lava instead of sand and will no longer be able to retreat.
Passengers on Air Iceland’s flights between Reykjavík and Egilsstaðir, East Iceland, were able to enjoy a view of the volcanic eruption in Holuhraun yesterday, as there was a clearing in the cloud cover above the eruption site.
The subsidence of the caldera in Bárðarbunga continues to cause uncertainty about the future development of the eruption. An event of this magnitude has not occurred since 1875 when Lake Öskjuvatn was formed in an eruption which caused major difficulties in Iceland and contributed to the mass...
High levels of sulfur dioxide emitted from the Holuhraun eruption were detected in Reyðarfjörður at 2 pm today.
If a large-scale subsidence of the Bárðarbunga caldera occurs, an eruption might start at the edge of the caldera. Such an eruption would melt large quantities of ice, leading to a major flood in a glacial river.
