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.

This was recorded by the Portsmouth Sinfonia in an experiment where all the members of the orchestra would swap instruments with each other and attempt to play them to the best of their ability.
favorite things about this
- literally all the brass starts to get the hang of it and then the crescendos happen and everyone is like FUCK FUCK FUCK??? FUCK. JUST. BLOW RLY HARD.
- the strings are lazy but also the same. like u can tell a lot of the ppl w/ the stringed instruments may already basically know how to play stringed instruments. like there’s definitely a section at the beginning where you hear a good portion going “oh yeah this is like. a smaller/bigger version of what i do.”
- all you hear of any woodwinds is just “pffffttt??? pFFFTTTT???? PFFFFFTTTT I SAID PFFFFTTTT!!!!!” bc woodwinds are fucking HARD and you hear after like the first crescendo half of them just give up. they give up. they’re done. fuck this it tastes weird and my lips hurt.
- that trumpet. that person is fucking TRYING man they fucking GOT this. they may not have figured out notes but they figured out LOUD and they GOT this.
I JUST DIED
I SEARCHED THIS POST FOR AGES OH MY GOD
Sounds like the beginning of Insidious.
