The fissure eruption is continuing at a stable level with little variation. A curtain of lava fountains up to 70 m high is being erupted above the fissure and pahoehohoe type lava flows are expanding to several kilometers around it, forming a growing flat lava flow field.
The effusion rate along the fissure vent has been estimated to be up to an impressive 1000 cubic meters per second.
Update from IMO this morning:
"No explosive activity is observed, the eruption remains an effusive lava eruption. Visual observation by webcam and low level volcanic tremor on seismometers do not show any obvious changes since evening.

Seismic activity:

Around 250 earthquakes have been automatically detected until now. Most of them are located in the northern part of the magma intrusion, between the eruption site and south to about 10 km into Dynjujökull. Strongest events were up to around magnitude 2. The rate of events has decreased as a result of pressure release due to the eruption, but there is still ongoing continuous seismicity.

Several events have occurred around the Bárðarbunga caldera rim, strongest events were M4.2 at 03:09 on the southern rim and M4.5 at 04:59 on the northern rim. See maps.

In the broader Askja region, most events were located at Herðubreiðartögl, the strongest event there was M2.9 at 02:56. This area is a quite common place for seismic activity, the activity now is not necessarily caused by increased stress due to the intrusion (the tip of the intrusion is about 25 km SW of this cluster). Askja volcano itself was seismically quiet."

According to local news, the lava flows have already reached more than 3 km distance from the fissure vent. The eruption is much stronger than the previous one on Friday, with up to 10 times lava output. ... Read all
