It seems that Krísuvík volcano is inflating and deflating on regular basic. I do not know how regular this change is. But it has been noticed by Icelandic scientists how are bit puzzled by this behavior. Last inflation episode did last until end of the year 2011. Since then deflation did start again and is currently ongoing. It is uncertain if what this means. At the moment it is too early to know for sure if this means if that Krísuvík volcano is getting ready for an eruption. But if there was an eruption in Krísuvík volcano, it would be Hawaiian eruption so no volcano ash. Volcano ash eruption would only take place if an eruption started in Kleifarvatn lake. But the effects of that would be limited to local area (Reykjavík and other nearby towns). It would not create any global problems, as many would want to believe.
Inflation and deflation period have been the years 2009, from January to September. In May 2010 inflation did start again, that inflation period lasted until end of the year 2011. Since then deflation has been taking place. Today there is continues GPS monitoring in Krísuvík volcano. But it is unknown if this type of behavior has taken place before in Krísuvík volcano. But for now Krísuvík volcano is being monitored both with GPS and the SIL network. What happens next anyone guess.
Icelandic news about this.

Interesting. That is kind of like Kilauea having D/I events except those happen on much faster timing. I guess you can say that Iceland breathes. Or at least some areas. Thanks for posting this. It will be something to keep up on. Just so the BBC doesn’t start Krísuvík mongering now. LOL
I have now updated the regular donation button. It now includes options on how high amount people can donate to me on regular basic. New regular donations are now 12 months instead of 6 months. Current donations that are ongoing to do not change with this changes.
Do other volcanoes do this? And, if yes, is there a common pattern?
I am not sure if any volcano in Iceland does it to any extent. I do not think this is an common pattern.
I am not sure if it is common or not, but Kilauea has been having rapid D/I events since it started erupting in 1983. Also the resurgent dome in Long Valley has had a D/I event that took years, and may be inflating again.
Sounds like a male problem….
Perhaps we should call volcanoes by male and female names, the ones that D/I are males and the ones prone to violent unpredictable eruptions are female…..
…. and keep them well apart, Iceland has too many already.
;-P
Water flow/levels around katla are on the up. Are we seeing glacier melt with the onset of summer or geothermal activity?
This is just summer melt. It is now warm in Iceland.
A bit of rain and a bit of melt down too, I think.
