The University of Iceland earth sciences institute this week carried out new lava flow measurements at the volcanic eruption on the Reykjanes peninsula. Comparison with old data indicates that the power of the eruption has increased again after a quiet period.

Scientists flew over the eruption, taking photographs, on Tuesday this week. Visibility was good, despite some volcanic gases over part of Geldingadalir and the southernmost part of Nátthagi. The measurements have been used to create a new computer model of the area that can be compared to previous data.

As reported, the behaviour of the volcano changed in late June, when it started fluctuating between periods of powerful lava flow and almost total quiet. The longest break in volcanic activity lasted four days. A statement from the institute says volcanic activity has been more stable again since 17th July. 

The volcano’s active periods have lasted roughly 10-15 hours, and quiet periods have also been of a similar length. 

Average lava flow from 2nd to 27th July has been 11 cubic metres per second, which is an increase from eight or nine cubic metres between only the 2nd and 19th of the month. 

The lava field now measures 109 million cubic metres and its area is 4.3 square kilometres. The latest data indicate the lava flow rate has increased, while previous expeditions showed the lava flow appeared to be slowing. The statement from the earth sciences institute says there is no way of predicting when the eruption will end.
