You just can't really help but check out these amazing pictures of the Iceland volcano. That is lighting that is stretching through the plums of ash.
Lightning is not that rare in volcanic eruptions. The particles within the cloud contain the same positive and negative charges that create lightning in our severe thunderstorms.
These pictures were taken by Vilhelm Gunnarsson with EPA. More dramatic are the evening pictures with the lightning and the magma shooting into the air.
The jet stream is moving the cloud of ash farther away from the very busy air ports of northern England...but there is still a very good chance the plums of ash could cast gloom on the skies over Europe as the volcano shows very little change with the intense explosions.
