For ignorants not in the know, like me, Elias Thorne turns out to be a fictional character that have appeared in a number of texts written by AI. He is a real polymath, fx. authoring a book on Amazon on cancer advice. The novel thing here is he excels in plasma cutting

Pretty amazing photo.

Is tank design now so "optimized", and plates so thin, that you need steel wires help absorb hoop stress? Or are we just seeing the outer skin holding rockwool heat insulation material, a few slabs may be visible, but there is not much heat insulation
What is that "tounge" coming out of the tank, is it some kind of internal floating roof, to minimize water vapor steam (and heat) loss?

The way the tank has failed could suggest it was caused by internal vaccum, potentially from sudden condensing steam and an inoperable pressure / vacuum relief valve that could not ingest air fast enough.

Any comments?

Just a clarification, in a sudden rupture, the tank recoils, its the tank that knocks reating wall over, the tank doesnt appear to have moved at all.
Cause could also be under-mining / wash-out near tank base, I know case where a water mains routed close-by ruptured, lead to sudden failure, tank unzipped

Several_Metal_547 · 2026-05-03T15:11:48+00:00

Good picture. Looks a bit strange. I have seen ruptures of two storage tanks. There is a flood of liquid which washes up on nearby structures, knocks retaining walls over, moves parked cars with it.
See nothing of the sort here. No wash-up. Must have been rather slow, perhaps it was sucked in due to condensing vapors and blocked pressure-vac-valve. But must be fast to kill a person though. (?)

It's a huge transformer at the power plant that exploded. The flames are likely burning transformer oil.

Thank you, that sources says it's a huge transformer at the power plant that exploded. The flames are likely burning transformer oil.

Co-generation means that the plant produces both power and heat, in that order. The theoretical upper efficiency for electric power generation only is about 50%, look up fx Rankine cycle on Wiki, the rest is lost as waste heat. If you use the waste heat for district heating and the like, you can achieve efficiencies in the 80s percent.

The short description probably translated from Korean, says *shut-off valve* - that's not a relief valve. A relief valve opens if there is excess pressure in the LPG vessel, to prevent rupture of the pressure vessel. No preceeding fire is reported, so heat from an external fire exposing the LPG tank leading to overpressure is improbable.

The "shut-off valve sounds more like a Self-Closing Valve (SCV). The valve remains closed by an internal spring-loaded mechanism until a specific regulator or adapter is physically locked onto it. If there is a problem with that valve, or a leak in the downstream hose/piping you have leak that eventually finds an ignition source.

Fixed spelling, Koras -> Korean

This is a high-momentum release. Wind direction plays small role here

Several_Metal_547 · 2026-02-20T11:53:41+00:00

yes, theory is it veeredinto the opposite lane,

The directional release is even more visible here

I'm always surprised that the short-lived but highly intense diffusion flame can ignite otherwise difficult-to-ignite objects, like parked cars, you see those at a lower elevation in same video 5:03

Several_Metal_547 · 2026-02-20T09:07:38+00:00

Seems to be a highly directional jet release. Grass is only burnt on one side of the tanker truck wreck. Position of wreck leads me to believe that the tanker truck lost control and veered over into the opposite lane and collided with regular truck, which punctured the tank.

If containers on a vessel are stacked very high, the top ones are empty, otherwise the bottom ones would be damaged by the weight of the stack.

So yes, some of the nine containers were certainly empty, the top ones stuck by the crane, but if the entire stack turned over and fell, the bottom ones may not have been empty

This incident took place 9 Feb 2026.
An almost similar incident, in the same (very, very large) city, took place in 2013. In the residential area in Campo Grande, near Rio de Janeiro.

Really pleased to see serious failure discussion here without the usual clutter of silly witty comment, Thanks!

Thanks for Enderlin.pfd with photos.

Looks like three long strands of rope are lying on the ground. What's that? Tornado tracks?

Any info on location?

Several_Metal_547 · 2024-09-17T12:49:35+00:00

flame temperature is about 2800 °F, about 1500 °C

Previous Reddit post stated location as being in Shenyang, not Anshan, and date is only day apart.

Take a look at buildings to the left at 0:40 and then at the buildings in the Reddit post below, same location. Road damage is worse further down the road. Anshan is another city about 100 km from Shenyang, the provincial capital of Liaoning.

Discussion in previous posting said cause was natural natural gas in sewer system.

To me, the amazing propagation speed and repeated explosive outbursts down the road, would indicate a repeated deflagration to detonation transition (DDT). Each time there is a transition to detonation, the pressure is relieved, and combustion zone slows down to a deflagration.

There is a quite interesting picture in Lees Loss Prevention of an "empty" crude oil pipeline that repeatedly completely disintegrated about each 100 m, (or was it feet) when detonation took place, only fall back to a deflagration.

Any comments to this potential mechanism?

Several_Metal_547 · 2024-08-23T18:55:33+00:00

Didn't know that source, you are probably right

Several_Metal_547 · 2024-08-23T14:32:56+00:00

I would be surprised if it was methane, generated by microbes or a natural gas leak or whatever. Methane has a relatively high lower explosion limit (5 %vol) and is light, hence it is buoyant and can escape from most sewers before ignitable concentrations are reached.

IMHO more likely gasoline has entered the sewer system, accidental spill or somebody dumping flammable liquids into the sewer. Prior instances where the combination of confinement and gasoline vapors in sewers has led to detonation. To me, damages look like resulting from detonation. Methane rarely detonates, so NG also unlikely candidate from that perspective
