Fluctuating volcanic activity, but steady lava flow

There has been a significant reduction in volcanic activity at the eruption on the Reykjanes peninsula in recent days. Geophysicist Magnús Tumi Guðmundsson says there is much less activity now than has been normal so far this summer.

“It clearly changed about ten days ago when it entered this unstable phase, when it has blown up spectacularly and then been very quiet in between. Now we are in a quiet period for the past two days or so, when there is very little activity, and the past ten days are overall rather quieter than it was on average,” Magnús Tumi says.

Is the eruption ending? 

“It’s extremely difficult to say, and not possible to to predict, because it could just be fluctuations in the activity. But it does look as though it is slowing towards that. It wouldn’t come as a surprise if it was, because most eruptions in this area won’t get much bigger than this. But, on the other hand, it is not possible to say anything for sure at this time.” 

What about lava flow? 

“An aerial survey has not happened since Saturday nearly two weeks ago, but we do have measurements from Meradalir that we can look at. They show that a lot has flowed into Meradalir over the past days, so it is not possible to claim that lava flow is a lot less than it was,” Magnús Tumi adds.
