Daily update on Bárðarbunga volcano, 15-September-2014

This information is going to get outdated quickly.

Current status at 12:59 UTC

  • Largest earthquake so far is a magnitude 5,4 that took place at 08:04 UTC.
  • Caldera has so far dropped 45 cm of today. Largest drop took place during the magnitude 5,4 earthquake and that lowering continued for two to three hours after the earthquake.
  • Eruption in Holuhraun continues at similar rate as yesterday (14-September-2014). Now it is mostly one crater that is erupting. The flow of lava is also not powerful enough to cross the river. So now it is spreading out from the central crater in all directions.
  • Earthquake activity has been moving south along the dyke. This means there is higher risk for earthquake eruptions under the glacier. There have been several minor eruptions under the glacier already.

Current status at 20:51 UTC

  • New vent has opened up south of current eruption. I can’t tell from Míla web cameras if this is a new vent or just old vent getting active again.
  • Most of the eruption continues in the central crater at the moment.
  • The rifting phase of the activity in Bárðarbunga volcano is going to take months to finish. In that time there are going to be more earthquakes and more fissure eruptions. There is also high risk of new dyke intrusions going into other directions from Bárðarbunga volcano.
  • If the Holuhraun eruption ends, a new one is going to start soon after in different place of that dyke. It might be on glacier free area or under the glacier. There is no way of knowing that for sure.
