This information is going to get outdated quickly.
Current status in Bárðarbunga volcano at 14:47 UTC
- The largest earthquake so far is magnitude 4,8 in Bárðarbunga caldera. There is however continued activity in Bárðarbunga volcano caldera so this number is going to change as the day goes on.
- The eruption in Holuhraun does not show any signs of ending any time soon. The lava field is now around 37 square km in size. It is growing in size every hour. There is no sign of less production of lava coming from the active craters in Holuhraun. The lava field is not getting longer, it is getting wider instead. Since the lava does not have energy to get any further then it already has.
- There is continued risk of new eruptions in Holuhraun and south of it, including under the glacier.
- According to Ármann Höskuldsson geologist at University of Iceland both Eyjafjallajökull volcano eruption in 2010 (information here, Wikipedia) and Grímsfjall volcano eruption in 2011 (information here, Wikipedia) were smaller then current eruption in Bárðarbunga volcano and connected events.
- It is expected that eruption is going to start in Bárðarbunga volcano caldera. When is not known.
- Bárðarbunga volcano caldera continues to subside at the same rate as before, that rate is currently 50cm/day.
- More magma is flowing into Bárðarbunga volcano from depth (more than 10 km deep source). It is clear that current eruption and earthquake activity in Bárðarbunga volcano is going to continue for months at shortest. This might go on for years at the longest. With minor breaks as often happen in fissure eruptions.
- On 1-October-2014 the eruption in Holuhraun has been ongoing for one month.
Current status in Bárðarbunga volcano at 20:24 UTC
- There has not been any major changes since earlier today. At 13:36 UTC a magnitude 4,7 earthquake took place. Other earthquakes so have been smaller.
- There was (or is) a quiet period for the past few hours. This might be because more magma is flowing into the magma chamber of Bárðarbunga volcano. Increasing the pressure and at the same time creating fewer earthquakes. That might change at any time without warning.
Update at 23:13 UTC
- The lava field at Holuhraun is now 0.5 km³. It is now the second largest lava field in Iceland during the past 150 years. Only Hekla lava field from 1947 is larger at the moment, it is 0.8 km³ in size. If the Holuhraun eruption continues as it has, it is going to get Hekla lava field size in about two weeks.
If anything new happens I am going to add that information here.
