Update on Bárðarbunga volcano and high conductivity in Jökulsá á Fjöllum glacier river

Conductivity remains rather high in Jökulsá á Fjöllum as it has been doing since before 14th of November. The source remains at Bárðarbunga volcano. The conductivity has slowly been getting lower since it peaked before 14th of November (I’m not sure when the peak was). Yesterday (18-November) I did notice the news a little discussion about Bárðarbunga volcano. It was stated that at least one cauldron in the glacier above Bárðarbunga volcano is so hot that is makes a steam trough the glacier. I have also not hear any other details about the reason why conductivity remains rather high in Jökuls á Fjöllum glacier river from the observations yesterday.

The steaming hydrothermal systems means there is a considerable energy in Bárðarbunga volcano system at the moment. This also invites the risk that next eruption cycle in Bárðarbunga volcano is going to large. This also increases the risk of small eruptions that are also hard to detect and might not break the glacier surface, unless they happen close to one of the new hydrothermal areas.

When next eruption cycle starts in Bárðarbunga volcano is impossible to know.

  1. It seams that the whole Vatnajökull system are awake since 2014. Bárðarbunga gave maybe Öræfajökull a push. Maybe the total Zone including the tail down to Öræfajökull has gone more dynamic during the last years.

    1. I’m not sure, what you mean. Moving lights, becoming brighter and darker again while moving slowly around?
      These were the beautiful Northern Lights or Arora Borealis! Here is a live and colour webcam from Senja/Norway.
