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.
