Several volcanoes are showing signs of activity.
But this is also normal.
Because of this, it's difficult to predict which is going to be the next and when.
Hekla should erupt because it has been doing so every 10 years, last time was in 2000. Hekla has only earthquakes 30min before the eruption. However,
sometimes Hekla goes long periods dormant.
Katla because it tends to erupt about 6-12 months after Eyjafjallajökull. Also there has been continuing earthquakes in Katla since Eyjafjallajökull
began erupting. These are mostly located in the NW of the caldera, the most likely place for a future eruption. No signs of the caldera inflation yet:
magma should still be well under. Katla should erupt somewhere within the next 2-3 years.
Bardarbunga and Grimsvotn are other sister volcanoes, located close to each other. Both are due to eruption. Grimsvotn does so every 5-6 years!
Bardarbunga erupts less often. But both have been showing lots of earthquake activity and Grimsvotn significant inflation. Both are very active
volcanoes. It wouldn't be any surprise to see Grimsvotn erupting this winter. Or an eruption somewhere along Bardarbunga fissure within the next 5
years.
Askja has been also showing some movements, and earthquakes, though less. This might mean an eruption is coming closer, but might only happen within
the next 10 years.
Other volcanoes are very quiet. There are some earthquakes also in the Reykjanes area, where there are several volcanoes, but they might be of
tectonic nature.
Therefore the next eruptions should be:
2010-2012 Grimsvotn first, maybe also Hekla.
2011-2013 Within the next 3 years, Katla.
2020? And somewhere within the next two decades, Askja.
