This is a short update on Askja and Bárðarbunga volcanoes. This information is going to get outdated quickly. I am not going to use pictures from now on (in most cases), since the situation now is complex and is going to go more complex as this goes on.
Summary: The Bárðarbunga volcanic system has been highly active in the Holocene with at least 26 eruptions in
the last 11 centuries. The last eruption took place in 1910 CE. The Bárðarbunga system lies on the Eastern
Volcanic Zone and is about 190 km long and up to 25 km wide, consisting of a central volcano rising to 2009 m
a.s.l. and a fissure swarm partly covered by the Vatnajökull ice cap. The central volcano has an 80 km2 ice-filled
caldera. The characteristic activity is explosive basaltic eruptions occurring on central volcano flanks or the
fissure swarm. Known eruptions have mostly been VEI 3-4 but occasionally VEI 5-6 (bulk volume of tephra up
to 10 km3
). The largest eruptions occurred in the early Holocene, effusive basaltic eruptions on the fissure swarm
with lava volumes ≥20 km3
. Eruption frequency during the last 1100 years is 1 eruption per 50 years on average.
Eruptions on the ice covered part of the system have the potential to cause major floods in several rivers flowing
southwards and northwards from the Vatnajökull ice cap.
Lava eruption has begun in Holuhraun, north of Dyngjujökull. The Met office confirms that and webcams in the area show that lava is braking it´s way up on the surface.
First news from the Civil Protection in Iceland tell us that the Lava is making it´s way up on the surface in a 400m long area north of Dyngjujökull.
The eruption is located on an ice-free zone which tells us that no ice is being melted so far causing floods in rivers in the north of Iceland. „This is probably located on the north end of the lava tunnel that moves from under Dyngjujökull. The eruption is located on an ice-free zone“ says Rögnvaldur Ólafsson from the Civil protection in Iceland.
„The eruption is not a big one, but we urge people to be safe and not go to near the eruption,“ says Rögnvaldur. „There are chances of explosions.“
Fissure eruption in Holuhraun lava field
A fissure eruption started around midnight in the Holuhraun lavafield, ca. 9 kilometers north of Dyngjujokull glacier. Lava streams out of a 100 meter long fissure, in the northern part of the lava field, about 15 kilometers south of the Askja caldera. IMO has issued a red alert for aviation
The eruption seems to have started near the northern end of the magma intrusion that has been propagating northward from the Bardarbunga caldera since August 16.
Small surface crevasses were seen in the Holuhraun lava field yesterday, leading to increased interest among scientists. The possibility of an eruption migrating southwards, towards the Dyngjujokull glacier cannot be excluded at this time.
