The southernmost vent at the erupting volcano on the Reykjanes peninsula has become more active and is throwing lava more than 50 metres into the air rather than the previous 10-15 metres, according to volcanology professor Þorvaldur Þórðarson. “It is a very big change to the eruptive behaviour, but the question is whether it also indicates increased productivity: whether it is growing in regard to the amount of lava being erupted.”

Þorvaldur said today it is not yet clear whether the more explosive fissure is a sign of greater lava production—especially because the other vents appear to have become slightly less active. “It could also mean that the activity has started to concentrate more on one fissure vent.” Scientists are researching the changes today, both in the field and using data from monitoring equipment.

“It is quite a stable eruption column and by far the highest we have seen during this eruption,” Þorvaldur says. 

The eruption was clearly visible from many spots in the capital region last night, and further afield. The clear skies helped, but the more vigorous eruption will also have made the volcano visible from further away.
