Quite simply, volcanoes are inspiring. I’ve yet to meet someone who disagrees. The majestic volcanic landscape has thus been an inspiration to many an artist and author, whether intentional or not. Furthermore, artwork itself can be a valuable tool to help decipher and understand eruptions and their effects on the climate. Pictured here is Vesuvius

While Iceland has enjoyed a couple years now of near silence from its restive volcanoes, that may soon come to an end with the awakening of it's most active and dangerous volcano, Hekla. While there is no indication seismically that the volcano is due for imminent eruption, scientists say that the magma chamber is full, and primed for eruption at any time. Hekla volcano is not known to give much advanced warning when it erupts, like some of its neighbors. Indeed, most eruptions from Hekla have [...]

Volcanic lightning is one of the few things that could make an eruption even more spectacular. Doubtless you’ve seen the recent photos of this phenomenon from the eruption of Mount Kelud in Indonesia – lighting up a huge ash plume at night – or from any number of eruptions in the past few years, from Puyehue-Cordón Caulle  in Chile in 2011 to Sakurijima in Japan in 2013 to Eyjafjallajökull in Iceland in 2010.
