“Apocalyptic” seems the best word to describe the images now emerging of ongoing eruptions at the Puyehue volcano range in southern Chile.
Eruptions began after an ominous series of earthquakes on June 4, resulting in heavy ashfalls, including in Argentine towns up to 100km away.
The phenomenon of eruptions producing such dramatic lightning storms was first observed in 2007.
The last time Puyehue erupted was in 1960.
