It seems that there have been few glacier quakes in Mýrdalsjökull glacier over the past few days. This glacier quakes are created by rain or some other movement in the glacier it self. This glacier quakes normally take place when there is heavy rain, or when the glacier is just moving because of water that is flooding below it. Sometimes glacier quakes also appear to happen around hydrothermal areas, but those might be harder to detect due to distance.
While not on the automatic earthquake list due how poor quality the glacier quakes are. It is still possible to see them on the tremor charts that Icelandic Met Office has on-line.
Glacier quakes seen on tremor chart of Icelandic Met Office. The quakes create an pattern of spikes on the tremor chart, it mixes into the other earthquake activity currently taking place in Katla volcano. Copyright of this picture belongs to Icelandic Met Office.
Same as above. Bust just stronger then on Lágu Hvolar SIL station. Copyright of this picture belongs to Icelandic Met Office.
This glacier quake activity has also been taking place in Vatnajökull glacier. But the force for the glacier earthquakes in Vatnajökull glacier seems to be weather (rain and sun), rather then hydrothermal activity.
Glacier quakes can be seen close the 28th June line on the tremor chart. But most of the activity does not get recorded due to strong wind at the same time. Copyright of this picture belongs to Icelandic Met Office.
Other then this, it is quiet in Iceland. Both in earthquakes and volcanoes.
Update: I did update the history list for eruptions in Iceland to include the last eruption in Grímsfjall volcano.

Just wondering if something is going on at Krisuvik?
Looks like someone has turned the monitor up the right way and it’s now recording the correct way!
Good morning Jón,
How about the quake MW 1.1. at 6.1 km, that’s no ice (strength 77,78).

What has happened to everyone? Since tony’s post of 10:39 hrs., no one has posted anything? All beamed up to starship Enterprise?
Think it’s because nothing is happening earthquake and volcano wise in iceland 😛 Nothing to talk about
With this weather? Who could blame anyone? 😉
Waiting for hefty thunderstorms starting tonight in S & SW Finland…
Can’t be much left. We had most of it here in Holland. ;-))
No, no… The meanest thunderstorms come to Finland typically from Baltic or Russia, or are weather front storms (hot air coming typically from the Baltic or Russia, and cold air coming from the north or Sweden).
I’m here!
Happy to report Katla is now on view again. http://www.ruv.is/katla
Many thanks to all who service these cameras. They are appreciated.
I have learned not to get all excited and mention things I think may be interesting as it usually turns out they are in reality “normal”. However Askja and Krisuvik look interesting to me. Things are going on but slowly and without drama. Observing for me is a learning experience. I love this site!
I hate to bring this up yet again. But I am going to be yet again really broke in July. Due to Visa final payments and because school in Iceland is expensive. But after July I hope things will start to get better. Because I have closed down my Visa card in Iceland, so that is no more.
So donations are welcomed to help me with this problem. Obama asks for donations, so I can to. But the difference between me and Obama is that he is already an millionaire, while I am rather poor man.
I have no interest in any type of power, so I don’t speak about that difference.

Interesting post on Katla Jon, what do you think?
