I have no idea what to do if I see this
Go to the breaker box and pull the big one labeled "main". Then call the fire department.
Get the fuck out and call the fire department.
Leave immediately and call 911 for an impending gas explosion. Tell them exactly what you saw, it will need to be disconnected somewhere very far away from the house. Aside from this being an obvious fake if you see a glowing pipe it’s the result of a deadly serious electrical fault that has bypassed at least 2 safety mechanisms that would otherwise prevent this catastrophic failure and at that point you really don’t even want to be touching the walls of the structure involved.
Someone linked a story that didn't have an image (didn't watch the video) so this may not actually be fake
Run. That's what I would do. Then probably call the fire department, the gas company, or an exorcist. Possibly all 3.
Either turn off the gas if you can safely do it, or call your gas company so they can shut off the supply to your house.
So there's an air leak upstream allowing a fire inside the gas line. And the house didn't go up in flames I assume. Probably this situation would not end in a big explosion but rather just a house fire. Still pretty scary.
When this was posted on Reddit recently, someone claimed this was caused by a fallen power line that made contact with a gas line. So, power flowing into the house through gas pipe and back out through equipment grounds, heating up lower resistance gas pipes in the process.
Photo reportedly taken by fire fighters or gas company employees.
Edit: I meant to type higher resistance...
This makes no sense at all.
Why would only these two specific pipes get hot, so hot to glow, but not the other lines connected to it? And not the fittings around it? It's all copper, so even if the power itself doesn't heat them up, why would being connected to an extremely hot pipe heat it up. Since it's you know copper and being good at transferring heat is what it's known for.
And why would the lower resistance part be the part that get hottest? Low resistance means less loss, so those parts would in fact be the coldest of all.
Plus thin walled copper pipes can't get so hot they glow without melting or at the very least lose all structural integrity and break.
And a downed power line with a short to ground would almost immediately turn off. It's when there isn't a direct line to ground those things are dangerous. As soon as it shorts, it gets turned off at the source to prevent further damage, fire and not cause issues upstream.
Either it's Photoshop or someone has wrapped led lighting around some pipes.
Holy shit that must be some freak combination of factors. Thanks for sharing!
Both of the lines that are lit up are flexible aluminum couplings. They're required in some areas as the final connections to the appliances. They're in line with cast iron gas pipe and fittings. They are much more thin and way better at conducting heat.

Thanks for the clarification, pipes look like copper but might be cast iron.
Still doesn't fit with the explanation, aluminum has more resistance than copper, but not that much more. The resistance of cast iron is an order of magnitude higher than aluminum. So it would still be the lowest resistance in the circuit and thus the coolest part.
And cast iron is pretty good at conducting heat. Not as good as copper or aluminum, but still pretty good. We've been using the material to make pans and pots for cooking because of it's thermal properties. So the heat wouldn't just stop at the fitting, but continue on at least some ways.
Moreover it's physically impossible to get aluminum hot enough to glow like this and still keep its shape. It melts at 600 degrees C, well below the point where something gets red hot, let alone yellow like this. If the aluminum were to be this hot, it would be in a puddle and at risk of burning.
The flexible pipes are normally stainless steel. The main gas line is steel with thick walls so this seems plausible to me. Stainless steel has higher resistance than steel and is so much thinner.
Sorry, I meant to type higher resistance. On my water heater, the equivalent part that is glowing in the picture is a really thin flexible corrugated gas pipe that surely can carry much much less current than the iron gas pipe feeding it before it went really high resistance. I could totally see it glowing like this with enough current. But if it is aluminum (not sure if it is), what you said makes sense.
My gas pipe to the house comes out of the ground inside a plastic protective pipe sleeve, so I can imagine it possibly not having enough of a low resistance path to earth to trip one of the cutout fuses on the primary distribution line. Granted, mine also has a big ground wire bonding it to the house ground, which I would think would help here...
/shrug I was just sharing what I read. It was supposedly the explanation as to why local breakers on the house didn't trip.
Well that's truly fucking terrifying
ELI5 anyone?
"I've got a buddy who can do the gas and the 'leccy. Super cheap."
This happens when the neutral goes out in a house. Usually the waterlines will handle it, but if the house has pex the ground will go through the gas lines.
Especially if a high voltage line comes down on a gas meter for whatever reason.
Definitely run away and call professional… everyone i guess.
Shouldn’t everything be grounded through the panel as well? I know I have a ground wire running out to a copper plate in the ground next to my house and my understanding was that if the neutral goes that would serve as the path to ground. Is this house missing that feature or am I wrong?
Would killing the main breaker at least prevent the heating of the pipes so that the expert isn't walking into a potentially dangerous situation?
I think in this case the power heating the pipes is not coming from this house's electrical service, so killing the main breaker probably won't help.
I read that this happened due to a downed power line. Unfortunately, killing the main breaker would not do anything.
I'm a little concerned killing the main breaker might result in a sudden temperature change that might fracture the gas line. Of course if you turn the gas off you might get fried.
We found out a while ago that plumbing pipes aren't the best way to ground a house for a variety of reasons, and this is why ufers (grounding to foundation steel) and ground rods are now the NEC standard. Also, this is why bonding wires are important as well. If the plumbing were bonded to a proper dwelling ground system, the current would find a direct path to ground and trip the responsible breaker, instead of using the gas lines as a big ass resistor and creating the light show we see here.
I've never seen pex running into a house from the street/ground. It's always been copper up to the water meter at the very least and it's code (in NJ at least) to put grounding wire there.
I'm in a new development. It's all plastic.

Hey, there's particles, they are accelerating. You got what you paid for.
Normal person reading that: particle accelerator from TEMU
Me: oh god, there are TEMU particles??
Mom: "We have CERN particle accelerator at home."

Relevant username.
Showed my partner, they said, "Is this some kind of raaave??"
While it looks scary as fuck, wouldn't it not actually explode unless the gas pipe melted through? There's no oxygen in the fuel, so it can't combust. I guess as the gas heats up, it's also possible the for the tank or lines to spring a leak.
Either way, I'd be nopeing out and calling emergency services.
unless the gas pipe melted through
That looks pretty damn likely imminent to me...
I think you're right. I was curious, so I looked it up.
The melting point of copper is 1,085°C, and judging from this chart, its definitely getting close:
You ever see gas hookups in the US?
We use black pipe for most of the run. Cast Iron. The actual hookup itself is a flexible pipe...SS or Aluminum I think. Been a long time since I had gas. Sometimes they have like a rubbery-epoxy-ish coating but I assume that's now quite gone and stinky.
Def not cast iron, cast iron is used for waste pipes and it's brittle you could never get threads on cast iron. It's actually steel even if we call it black iron. A lot of newer houses will run solid pipe from the main to a central location and build a manifold with corrugated steal (flexible pipes) run to the terminal points.
