More Icelandic bubbling under

The geothermal field Krisuvik on the Reykjanes peninsula is busy with small and relatively deep tremors right at the moment. Grimsvötn is merrily bubbling away under Vatnajökull.

Nothing massive going on at present, but as no-one has come up with an accurate system of forecasting eruptions, it's so hard to tell.

Katla keeps bubbling under like a coffee percolator on low heat, but no other data to indicate anything untoward is happening. So no fireworks here at the moment. Thank goodness for that.
