This information is going to change quickly if anything happens in Bárðarbunga volcano.
Current status in Bárðarbunga volcano at 21:49 UTC
- There is no signs of the eruption in Holuhraun is about to end. Currently there are only one or two craters erupting.
- The lava field is now around 47 square kilometre wide. It grows in wideness at the moment, it is not getting any longer since the magma has not the energy to go any future than it already has.
- Earthquake activity continues to happen under the dyke and the eruption crater. So there is clearly high pressure in the dyke and not it is possible that the eruption that is now taking place is not large enough for the all the magma that is down in the dyke.
- Largest earthquake today had the magnitude of 4,8 and took place at 19:24 UTC. Second largest earthquake took place at 14:53 UTC and had the magnitude of 4,7.
- The lava that has now erupted in Holuhraun is two times larger than all of lava erupted in Kröflueldar eruptions that took place between 1974 – 1984.
- Bárðarbunga volcano caldera has now dropped some 30 meters according to Magnus Tumi Guðmundsson geologists at University of Iceland. There is a plan to fly over Bárðarbunga volcano by end of this week, when maintain of the air plain that is being used for this is done.
- Icelandic Met Office has confirmed that it is just lava flowing into Jökulsá á Fjöllum glacier river. This is not a new fissure at that location this time around.
- Rifting in Bárðarbunga volcano area is about what Iceland moves in about 150 year period. This is happening all at once and it does not appear to be over.
- Bad weather has prevented scientists from being in the area most of the week. The weather is not expect to improve until 2-October-2014, since new storm is expected tomorrow.
One month ago at Holuhraun
This is the news one month ago (almost to the day) about what is happening back then.
Tomorrow (1-October-2014) it is exactly one month since this happened.
How strong wind affects earthquake recoding
Here is a image from my geophone of how strong wind in north Atlantic ocean and Greenland sea affects my geophone recording and other seismometers in Iceland.
Here is how you read this image. First is the earthquake, the P wave is first, second is S wave, along with other wave forms that happen in earthquake. The wave patterns that is all over this earthquake recording is ocean wave from winds. Both the ocean waves that happen at the coast, but also the ocean waves at deep ocean far from Iceland coast line. The spike at 21:07:21 – 21:07:41 is a electric noise. The noise at 21:08:41 – 21:09:21 is an animal or some other type of noise source. This image is released under Creative Commons Licence. Please see CC Licence page for more details.
