Deflation stops in Krýsuvík volcano

According to Rúv News today. Deflation has stopped in Krýsuvík volcano. But this is the latest chapter in inflation and deflation episodes that have been taking place in Krýsuvík volcano during the past three years. It is unclear what happens next in Krýsuvík volcano. But an new inflation episode should not be ruled out at this point.

Lat inflation episode started earlier this year (2012) and stopped in May. Then an deflation episode started. It stopped sometimes in August 2012. It is impossible to know for sure when an new inflation episode starts in Krýsuvík volcano. But it is my opinion that is going to be soon. But how soon exactly is impossible to know. Inflation episodes in Krýsuvík volcano have been followed by strong earthquakes swarms. So that are the signs of an inflation period having started in Krýsuvík volcano.

Still no glacier flood in Skaftá glacier river

For reasons that are unknown. No glacier flood has yet taken place in Skaftá glacier river. Even if the western Skaftárketill cauldron in Vatnajökull glacier has emptied. It is now expected that Hamarinn eastern cauldron is going to empty it self soon. But when that might happen is impossible to know for sure.


Ice-quake activity continues in Vatnajökull glacier. But that suggests the water is on the move under the glacier. Copyright of this image belongs to Iceland Meteorological Office.

The glacier flood is expected to be small. But it won’t go unnoticed once started. As the glacier river get’s darker and conductivity in the water increases greatly during the flood. I am going to try and keep an eye out for more information on this glacier flood.

More fine ash in the volcano ash cloud from Eyjafjallajökull volcano eruption then predicted (2010)

Rúv News had an interesting news bit about Eyjafjallajökull volcano this evening. It was about the eruption that took place in the year 2010. While Europe did not get a lot of volcano ash as expected. The amount of fine volcano ash in the air during this period was more then expected. A lot more according to a research into the ash cloud that happened in April 2010. This volcano ash is an danger to air planes and jet engines.

The amount of fine volcano ash was underestimated by observing satellites. As they did not see this volcano ash clearly or just not at all according to the news about this study. The amount of fine volcano ash in the air at the time was about ten times more then current model predicted during the eruption. This study did use data from 400 observing areas. The study it self is published in Scientific Report. I have not located this study as of yet.

I am not sure what this means in terms of the flight ban that was in the effect when the eruption took place. But one thing is sure. The areas that where considered free of volcano ash simply might not have been that in reality.
