Edit: it looked to me like he grabbed the trigger when he picked it up, which makes it even dumber.

Depends on the gun. But yeah, generally speaking if this was any big name manufacturer like SiG/HK/Glock/etc. it is physically incapable of firing due to being dropped.

It always turns out the dipshit either pulled the trigger by handling the gun or got something caught on it.

Correct me if I'm wrong but didn't they fire if you just shook them lightly once? (May have been some other brand.)

No gun should ever fire when dropped, regardless of how the trigger is set, though obviously sometimes one occasionally will. It's a mechanical object like any other. Nevertheless, the designers try to get rid of that tendency.

Anyway it looks like in this case the gun did not fire when it hit the ground, but when he went to pick it up. He probably just pulled the trigger as he grabbed it.

I get the whole 'safe to drop' thing, what I'm more wondering is, here at least, you have to really work the trigger on a law enforcement firearm to make it fire. There it looks like he brushes the trigger tenderly and it discharges.

Some badly designed guns will, despite it being a solved issue mechanically in competently designed guns for nearly a century.

Law Enforcement triggers are pretty heavy, requiring noticeably more pressure on the trigger than the standard triggers.

This is why if you are in possession of a loaded gun you keep your fingers away from the trigger at all times unless explicitly intending to shoot someone. I would have hoped an FBI agent would have better trigger discipline than that.

EDIT: I mean also definitely don't take a loaded gun out when you're getting drunk, either.

I heard this was a really controversial thing? Like the facile argument is that if it's harder to pull the trigger you'll have fewer negligent discharges, but the other argument is that it screws up your aim and makes you more likely to pull to the side and shoot a bystander when you do inevitably go for the gun (because lol a heavier trigger pull isn't the thing stopping a cop from blowing you away).

Anyway, the pull is adjustable and this guy is FBI, not a beat cop, so I could easily imagine him having it set to a lower weight because high speed low drag tacticool smooth operator oorah oorah

You're actually right, it was a very long time ago. Komatiite lava was up to 500 °C hotter than the hottest lava today - 1700 compared to the 1200 we're seeing at Hawaii right now. The lava at Hawaii flows like room-temperature honey; Komatiite lava flowed like water, with the density of rock. We're talking Meso- to Neo-Archean, 3-2.8 billion years ago. The Earth's mantle and core were a lot hotter at the time due to relict heat from planetary formation and far greater abundance of radioactive elements that have almost all decayed today. As far as composition is concerned, Komatiite lavas are extremely Magnesium rich, and generally have very elevated (10-20 times greater than general crustal abundance) nickel, cobalt and chromium concentrations

Komatiitic lava was responsible for the formation of the deposit that my supervisor did his PhD on, the Kambalda massive sulphide nickel deposit in Western Australia.

Sweet, so depending on surface tension you could have a lavafall like a waterfall, and it could be misty and foggy at the bottom like a regular waterfall is, but with molten lava mist

I'd guess this would produce some form of extremely deadly dust as the droplets froze, but maybe it could act like how freezing rain does, or form vitreous hoar frost or something.

Is there any gajillion year evidence of such a thing or are my assumptions wrong or what?

The evidence for this would be insanely hard to find. When things happened literal billions of years ago, you almost always see some sort of reworking of them - whether structural (folding and faulting), metamorphic (heating up to the point the rock itself changes) or erosional (wearing away of the rock and deposition somewhere else as a different rock.

You could absolutely have a lava waterfall, but it would quite likely at least partially solidify on the way down and then just mound up like honey at the bottom. Generally what it did when it erupted (and we have tons of evidence of this through geochemistry) is that it aggressively wore away the substrate that it was flowing over and assimilated sulphur from it, which mixed with base metals in the lava to form ore deposits. So even if it was venting out from a Hawaii-style fissure, and going over a nearby fault scarp, it would wear the surface down to the point where it became a steep hill in the space of hours or days.

And a truly scary amount of them wear uniforms.

Also, I've carried a pistol before while in the Army Reserves, and I never dropped the loving thing even when I was jumping out of a plane. Plenty of guys in TFR carry daily with good quality holsters and don't lose their guns. I'm pretty sure there was a spate of police officers and security guards losing their service weapon by leaving it on a shelf or whatever while they were taking a poo poo in a public toilet and forgetting it was there.

It might be, but regardless of any controversy the Law Enforcement triggers in the US are heavy triggers.

Anyways, the important thing here w/r/t the video is that the guy seems to have negligently fired his gun by pulling the trigger while (drunkenly?) grabbing it off the floor. It didn't fire when it hit the floor. Basically the standard outcome of "it just went off!!" claims.

FBI doesn't modify or spec their standard issue duty weapons any differently from the way Glock builds any other 22. Its a standard-pull (5.5lbs) trigger.

The only law enforcement organization that I've heard of modifying duty weapons is NYPD mandating 12lb trigger pull weight. Thats across a few different standard duty weapons.

Glock, HK, SIG, etc. market LE triggers heavier than the standard. The FBI may not use them, but they also aren't putting match triggers or whatever on the guns and it still wasn't going off without something yanking on the trigger.

The current eruption is classified as being part of the series of eruptive events that has gone on since 1983, which put out around 4 km3 of lava to 2012, and buried a few towns to a depth of 35m along the way to covering 125km2 and destroying 214 structures. By way of comparison, the most recent event has now been going for a month and has already covered 20km2 and destroyed 240 homes.

This poo poo is an order of magnitude more lava than previously, which makes the answer to your question a big fat "who knows?". There's thinking it might manage to shoot its load pretty quickly and we'll see it settle down in a month or so as crystallisation along the extent of the dike causes it to clog up and find another way out. There's also thinking that because it's fresh off the mantle, we could be seeing the start of a really long period of volcanism that radically alters the geography of the area, as the heat is enough to actually eat into the substrate and clear its own path as it goes.

The fact that the only injury so far was that one dude has had his leg broken by a freak lava bomb coming down on it is a pretty solid testament to how well prepared the authorities and locals are to get the gently caress out of dodge when poo poo goes off.

That livestream that I posted a few pages back has had to stop broadcasting because their house isn't there anymore. They got out fine though, and Rusty evacuated with them.

Sorry if people are finding that there's a lot of vagueness in my posts, but this sort of poo poo is really hard to pin down as to what exactly is happening until it has already happened. If you get three geologists in a room and ask them for an opinion on something, you'll probably end up with four opinions, because one of them will change their mind after hearing what one of the others said.

Very different eruptive styles. Volcan de Fuego is a dacitic to rhyodacitic stratovolcano, with the magma being orders of magnitude more viscous. Therefore, pressure can build up much higher before eruption. They had series of pyroclastic flows there earlier today, and they're up to 25 confirmed dead :(

Here's a vaguely-stabilised video of one of the flows. Tell you this for free, I wouldn't be anywhere near that bridge once I had figured out what was going on.
