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.

Hold on to your genitals, ladies and gents, because the trailer for “Vengeance of an Assassin” is about to send orgasmic shock waves of splendor through your nether regions.

This is Panna Rittikrai’s (choreographer of “Ong Bak,” “The Protector” etc.) last film as, sadly, he died earlier this year. But, good god, he’s going out with a bang.
Look…I get it..the film looks pretty terrible. But just look how mental it is. Flying trains? Check. A man killing other men with a chicken bone? Check. Martial arts versus handgun goodness? Dam right.
Everything about this film is so wrong that it might just be right. So right. It’s like “Bangkok Knockout” on PCP.

I’m going to be at least six beers in when I watch this bad boy.

Side note: The trailer doesn’t get good until about halfway in.
