Bardarbunga volcano update: Eruption continues, small earthquake swarm under Tungnafellsjökull volcano

Updated map of the lava flows from the eruptive fissures (triangle) (IMO)
The eruption at Holuhraun continues at similar intensity. It appears that the lava output is now balancing the magma influx at depth, most of which seems to be draining from the reservoir underneath the Bárdarbunga caldera, which reacts by subsidence.
Earthquakes around Bárdarbunga today so far (IMO)
Lava flows from the main fissure expand east and north. The main lava flow now follows the river bed of Jökulsá á Fjöllum, but no explosive activity due to the lava and river water interaction has been observed.
IMO warns of high concentrations of sulfuric gases that reach dangerous (even life-lethal) levels near the eruption site and are likely to affect the downwind areas including the northern part of the Eastern fjords, Fljótsdalur, Hérað, Jökuldalur, and Vopnafjörður.
Earthquake activity in the caldera of Bárðarbunga remains similar to that of the last days. Epicenters are distributed along the northern and south-eastern caldera fault. An earthquake of M 5.3 occurred at 00:07 h. Earthquake activity at the dyke tip has decreased. More than 30 events have been detected since midnight. Low frequency tremor is similar to what has been observed in the last few days. (IMO)
Earthquake swarm in Tungnafellsjökull
A smalll earthquake swarm has been occurring under the Tungnafellsjökull volcano located to the NW of Bárdarbunga since yesterday. According to scientists from the Iceland university we talked to today, this was likely a result of an intrusion from magma from Bárdarbunga which disturbed the other volcano's own volcanic system.
In a similar way, all surrounding volcanoes (including Askja, Kverkfjöll and Grimsvötn in particular) have been disturbed by the ongoing activity.

The eruptive activity at Holuhraun has not decreased, the Icelandic Met Ofccie writes: "Magma flow is between 100 and 200 m3/s. The lava advances by about 1 km/day and its area yesterday afternoon was around 16 km2. ... [mehr]

The eruption continues at similar levels as during the previous days. At the eruptive fissures, most lava emission in the form of lava fountains is now concentrated from the central vent on the main fissure. ... [mehr]

Eruptive activity at Holuhraun is the same as yesterday. Two eruptive fissures are active, with most activity continuing at the same fissure that opened up a week ago. In addition, the fissure that opened yesterday morning is still active. The lava now extends 10 km ENE and has just under one km to reach Jökulsá á Fjöllum river. ... [mehr]
