Eyjafjallajökull, an ice-capped volcano in Iceland that last erupted in 1823.
We talked a few weeks ago of signs that there were increasing signs that an eruption could occur on Iceland - increased seismicity on the Reykjanes Ridge suggested that magma might be on the move. Now, we have two pieces of evidence that we might see activity at Eyjafjallajökull, on the southern side of the island nation.
First off, there is a focus of seismicity under the area of Eyjafjallajökull, with an especially large bump in the last 2 days. Both the number and magnitude of the seismicity has been marching…

The Icelandic coast of Reykjanes where the Mid-Atlantic Ridge comes above sea level.
A number of Eruptions readers have noticed that seismicity along the Reykjanes Ridge that runs to the southwest of Iceland onto the island has increased over the last few days. Sure enough, checking the Icelandic Met Office page on seismicity on the island finds a lot of earthquakes on the southwest peninsula that is the manifestation of the Mid-Atlantic Ridge hitting the hotspot-related Icelandic landmass. The interaction between the Iceland plume and the Mid-Atlantic Ridge is complex, with a step in the…
