Plotselinge stijging van de harmonische tremoren rond Katla en Eyjafjallajökull
Sudden rise in harmonic tremors around Katla and Eyjafjallajökull
There is a sudden and sharp rise in harmonic tremors around Katla and Eyjafjallajökull volcano. I currently do not know what volcano is responsible for the spike in harmonic tremor. But this does not look like is a noise from the weather. But that can happen often this time of the year, as the wind forecast is good for all of Iceland at current time.
I will post more information if and when I get them.
SIL stations where the harmonic tremor rise can be seen.

GrÃÂmsfjall continues to inflate
Posted on October 10, 2010 by Jón FrÃÂmann
I see that many people think that GrÃÂmsfjall has started to deflate due to a drop in GPS measurements. But the “Up†part of the GPS measurements have been dropping over the past few days from about 85mm and down to about 65mm today.
As that may be true that the mountain has started to deflate from the top. It is not to say that deflation process has started at GrÃÂmsfjall. As the GPS data clearly shows that a inflation process has just moved from the top and to the south. But current GPS measurement clearly show that GrÃÂmsfjall is now inflating to the south (15mm today) with minor inflation to the east (about 15mm today). So it is clear that the magma is moving inside the volcano from one location to a other over the past few days. What that means is unclear at the moment. But it appears that the inflation to the south is speeding up at current time. This might get interesting soon in my opinion. Regardless if there is a eruption or not.
Data: ISGPS GFUM
Vatnajökull continued GPS data project from 2004.
het zal daar nooit echt rustig worden

GPS changes in GrÃÂmsfjall due to ice on GPS antenna
Posted on October 11, 2010 by Jón FrÃÂmann
I did just speak with geologist at Icelandic Met Office and the he told that the recent changes in GPS measurements in GrÃÂmsfjöll where not real. But they where created by ice. But now the ice has been cleared of the GPS antenna and the data is now correct.
But the real movement is to the south and GrÃÂmsfjall has continued to do that. So GrÃÂmsfjall is continues to inflate at relative fast rate and prepares for a eruption as magma flows into the GrÃÂmsfjall magma chamber
