This proposal wants to add the value fiery_fountain to the natural key to describe a particular natural gas spring that has often a self-sustained flame.
https://wiki.openstreetmap.org/wiki/Proposal:Tag:natural%3Dfiery_fountain
Please discuss this proposal on its Wiki Talk page.
I think the thing you are describing is called a “gas flare”? Unless that’s just for industrial usages and this is something different.
I do think “fiery fountain” is a really fun name though 
The one you linked is man made, the one i’m doing the proposal of is natural. I don’t know if it’s the correct name in english, since it’s a pretty rare thing i didn’t find much information online aside from the wikipedia page I linked in the initial post. And yes, I like the name very much
You’re talking about a geiser(?), there’s a tag for that, something like old faithful in yellowstone park
No, it is about a natural inflammable gas outlet in the ground, similar to a man made
but being a natural object. There must be less than a dozen all around the world, so I don’t think a proposal is necessary for such a few objects - I’d rather discuss the correct naming in english here and then document it in the wiki.
yes, it is but I have some doubt that this is a common description for these gas outlets … 
Again, in these times of sustainability and greenhouse gas reduction I believe sooner or later these few outlets will be covered and connected to some pipeline anyhow, to make use of the gas - so we should think about a tagging which can still be used when there is no more “fiery fountain” any longer … 
I only found the name in italian and french since both country host at least one of them
There is also Darvaza gas crater - Wikipedia
It has natural=crater - how it would be tagged now? It is actually a crater from what I see.
The only obvious answer is natural=fiery_crater.
A fiery fountain sounds like something you’d see at a really cool new Year’s Eve celebration. Sounds awesome! 
According to the WP article it is not a natural object, but man made … so I would tag it as
tourism=picnic-site with
amenity=bbq
covered=no
fuel=gas
capacity:persons=5000
Btw: Reading the WP article, what did I say …?!?.. they want to cover it up, collect the gas and sell it.
How many of these are there in the world? The impression I get from Wikipedia is that they’re exceedingly rare – the Wikipedia article identifies two by name, while Commons has pictures of another six. Is there really a need for a distinct tag that will only ever be used eight times?
@Carnildo There are very few, I agree. But what is the other alternatives? I mean, if there’s no correct tag for them I don’t see another valid way to go
Why not? I admit that it is unlikely to be supported in various applications, but it would not really harm anyone.
(and once this tagging is used I will definitely check whether I have any nearby!)
Remember that in OSM you can use any tag you like. To start mapping them you don’t need a proposal.
That’s cool, I just wanted to make it “official”, but if it’s not needed for tag with few use cases I will probably reconsider it
Remember that in OSM you can use any tag you like. To start mapping them you don’t need a proposal
sure, but if you make a proposal and speak about it, others become aware and also use the tag - or find it later on when searching for it.
