Volcano on world map.[edit]
600px Changes to articles were made as needed.
Where volcanoes form...? (verify)[edit]
The statement about volcanoes forming around the edge of oceans looks wrong to me. I was unaware of any such trend on the worlds I've seen so far. As I understand it, there is a magma activity map that varies across the the world and 'peaks' at certain points in the terrain creating volcanoes. I don't know how toady has implemented that, but I'm sure it has nothing to do with the rims of oceans. --Markavian
Cavern collapse[edit]
Is not related to the generation of water above magma and instant crystallisation and collapse. Because I got that phenomenon when I settled at an extinct volcano (no magma present in pipe). --Juckto 07:35, 29 June 2008 (EDT)
Erupting volcanoes[edit]
It would appear that volcanoes can now erupt http://mkv25.net/dfma/movie-685-volcano#lastComment;?%3E Diabl0658 03:19, 24 July 2008 (EDT)
- Nope, that's just a (somewhat) common bug where a volcano and a bottomless pit are generated on the same spot. Here's another video of the same bug, where the poor dwarves embarked right next to the lava. http://mkv25.net/dfma/movie-701-shortestfortever Spoggerific 15:33, 12 August 2008 (EDT)
- Does this bug occur immediately on embark, or anytime? I've had a volcano appear to erupt quite a bit after I embarked, it spit fire everywhere, and burnt up a bunch of the landscape (and several of my dwarves). JubalHarshaw 11:39, 31 December 2008 (EST)
- Depends on the version, if you're importing an old save, and if Armok wants to see a bloodfest. --GreyMaria 22:28, 31 December 2008 (EST)
This was the latest version, so I can pretty much confirm that yes, volcanoes do erupt now. Saw it again tonight.JubalHarshaw 23:13, 31 December 2008 (EST)- Having said that, I was also attacked by a Fire Man tonight, that produced pretty much the same effect ... fire everywhere, burning everything. So I guess I can't truly confirm volcanoes erupt, it could have been a Fire Man. JubalHarshaw 00:19, 1 January 2009 (EST)
- That depends - was the world burninating after the so-called "eruption" or was there just a solid sheet of ash among the trees? If it was the former, a fire man started the blaze; the latter, lava spilled over the world. This requires testing, apparently - time to embark over a volcano and survive for as long as possible. --GreyMaria 00:24, 1 January 2009 (EST)

That's not cool, I just got the latest version (finally) and I am living inside a volcano. Like there is this big circular cut through the mountain, and I dug through on the level above the magma and started a fort there, digging around the magma. Any tips, other than when I see strange activity order my dwarves to go downstairs and don't come out. I get the feeling I should move all of my stockpiles circling the vent... And I realize that not much is known aobut this, I just think some "general" safety tips would be a good thing to have now.--Destor 11:28, 1 January 2009 (EST)

Draining a volcano[edit]
I had read that magma tiles were supposed to be sources of magma.
So I am a bit suprised that having dug (admittedly a quite large) room in the bottom z-level then opened it up to the magma pipe, I have drained the top five z-levels of my volcano.
It has been several seasons now. I am wondering will the volcano pipe fill back up or have I drained it permenantly?

Trivial Stuff[edit]
A couple of things I found while experimenting, please verify:
- Volcanoes seem to cause high elevation in the surrounding area; even if the surrounding area is too low for the resulting mound to be classified as a mountain, every single volcano tile I've bothered to inspect has displayed as having extreme (20+) cliffs when viewed on the region map, even if it isn't technically a mountain. Amusingly, the crater is seldom at the peak of the mountain, as logic would seem to dictate.
- A bit of fiddling around with the world painter suggests that, instead of every 100-volcanism tile automatically being a volcano as the article implies, the game instead randomly picks (x) number of 100-volcanism tiles to become volcanoes, with (x) being the amount of volcanos specified in the worldgen parameters.
As a side note, I have to wonder about the wisdom of posting this here with the new version literally days away. --Mr Frog 17:17, 31 March 2010 (UTC)
- High elevation in volcano map tiles -> Verified. Don't know about the second. I'm surprised the high elevation bit hadn't made it in already; it's how I find mountainous territory in grasslands or mountain-islands. --Retro 17:27, 31 March 2010 (UTC)
