The craters from last years eruption in Grímsfjall volcano are clearly visible on new pictures that Rúv did release in the evening news. There also seems to be some increase in hydro-thermal activity in Grímsfjall volcano. Based on the pictures and what was reported in the Rúv news this evening (02.06.2012).
When the eruption was at it largest last year, the crater was around 1.5 km in size. But once the power started to drop in the eruption, the single crater did turn into several small craters. The glacier is slowly closing this new crater. In few years time, there are not going to be many signs in this are that an large eruption took place there.
The new images can be viewed in this news on Rúv news web page.

I notice things are hotting up a bit at Reykjanes Peninsula and Tjornes Fracture Zone, this seems to be a recurring pattern after a quiet spell.
The SIL’s look as expected, but the http://hraun.vedur.is/ja/oroi/grv.gif station looks a little more active than normal. This morning satellite thermal picture show s a general increase which is probably seasonal across Iceland, http://brunnur.vedur.is/myndir/modis/modis_btd_A20121542235.jpg however I note that there is a blip at the end of Reykjanes Peninsula – is there a connection between this and the activity on Grindavik SIL, or probably just an overactive imagination?
I have no doubt the eerily quiet Vatnajökull area will entertain over the coming weeks, and it is most noticeable in the satellite imagery, how clearly Askja lake stands out, although most activity seems to be to its East around Herðubreið. The IMO’s assertion that this is tectonic is good news.
A smallish, unknown volcano had a surprise up in her sleeves:

Thanks for this. Geology is full of surprises!
Iceland, south coast. Cockpit view

Thanks for the nice view! At my next trip to Iceland, I think I must book a little flight…
Speaking of suprises, Earthquake-Report is reporting a new emission from the volcano off of the coast of El Hierro.

This looks like new dike intrusion at depth in El Hierro volcano. At the moment it doesn’t appear to be big. But it is hard to know for sure if this means anything at the moment.
Until now there are 14 earthquakes today. The largest has 2,9.

Jon, are earthquakes helicoders Katla?

No. This is human noise. There is a lot of noise on this geophone, as it is on most of my geophones today.
