Amazing Puyehue-Cordón Caulle photos!

Puyehue-Cordón Caulle continues to erupt but with diminshed activity, there are detailed reports in the Eruptions blog by Erik Klemmeti and The Volcanism blog.

I have posted a couple of the more spectacular photos of the eruption column, I will be posting tomorrow about what causes the volcanic lightning so often seen in eruption columns! It's something which is seen so frequently that I feel it should be explained!
