In light of the ongoing threat of a sub-glacial eruption in Bárðarbunga, which would lead to massive flooding, the Icelandic Road Administration has decided to redesign a new planned bridge over the river Jökulsá á Fjöllum at Grímsstaðir.
Sulfur dioxide (SO2) pollution from the Holuhraun eruption peaked at 6,000 mµ/m3 in Höfn in Southeast Iceland at 4:30 this morning. Sulfur dioxide levels also reached extreme levels in the town yesterday morning.
Journalist and environmentalist Ómar Ragnarsson flew over Holuhraun last week and shot a new video of the eruption site, published on ruv.is. The video shows the expanse of the new lava field, which now covers 60.7 km2 (23.4 square miles).
Seismic activity in the Bárðarbunga system and volcanic activity at the eruption site in Holuhraun is comparable to recent days, the Icelandic Met Office reported this morning. A magnitude 5.3 earthquake hit on the northern rim of the caldera at 08:36 am.
Sulfur dioxide (SO2) pollution from the Holuhraun eruption peaked at 5,400 mµ/m3 in Höfn in Southeast Iceland last night. People in the area received an sms from the 112 National Emergency Number at around 7 am this morning alerting them of the pollution.
Three earthquakes of magnitude 4.5 or larger have hit the area around Bárðarbunga volcano in Vatnajökull glacier in the last 24 hours. In the past days, earthquakes around magnitude 5.0 have occurred in the area at an interval of approximately 30 hours.
The lava which has flowed from the craters in Holuhraun now covers 60 square km (23 square miles). The eruption is ongoing, although the volcanic activity has decreased somewhat. Scientists are examining data more closely and re-estimating the situation.
Residents in Ísafjörður and elsewhere in the West Fjords received a text message from the Civil Protection Department at around 11 pm yesterday evening, warning them that high pollution levels because of the Holuhraun eruption were present in the area and advising them to stay inside.
A subsidence of approximately 15 cm (5 in) occurred in the caldera of Bárðarbunga volcano in Vatnajökull glacier following a magnitude 5.4 earthquake hitting the northern caldera at 11:15 am yesterday, as indicated by the Icelandic Met Office’s GPS monitor in the caldera.
