photos of sakurajima, the most active volcano in japan, by (click pic) takehito miyatake (previously featured) and martin rietze. volcanic storms can rival the intensity of massive supercell thunderstorms, but the source of the charge responsible for this phenomenon remains hotly debated.

in the kind of storm clouds that generate conventional lightning, ice particles and soft hail collide, building up positive and negative charges, respectively. they separate into layers, and the charge builds up until the electric field is high enough to trigger lightning.

but the specific mechanism by which particles of differing charges are separated in the ash cloud is still unknown. lightning has been observed between the eruption plume and the volcano right at the start of an eruption, suggesting that there are processes that occur inside the volcano to lead to charge separation.  

volcanic lightning could yield clues about the earth’s geological past, and could answer questions about the beginning of life on our planet. volcanic lightning could have been the essential spark that converted water, hydrogen, ammonia, and methane molecules present on a primeval earth into amino acids, the building blocks of life.

Justice is Coming

The last time I was on a plane, I took a ton of photos, hoping I could stitch them together for some nice semi-panoramic aerial shots. And for the most part, they turned out pretty well, but then I envisioned passing iconic images embedded in the landscapes I was passing and thus, started working on this image series. I have a few more done and that I’m working on, but i wanted to wait till I had at least the trinity done before posting any of the series, so here’s the main Justice League set.
