+ | A '''volcano''' is a terrain feature created at worldgen. Embarking to a volcano site is the easiest way to obtain [[magma]], as a volcano has magma exposed to the surface rather than dozens or hundreds of z-levels below ground. The volcano will be consistently shaped all the way down to the bottom of the map. | ||
Volcanoes do not explode, erupt, nor spew noxious fumes, however, the level of magma within can fluctuate. For now, volcanoes are simply very large, very hollow pillars of [[obsidian]] with magma inside. They count as subterranean lava for the purpose of spawning [[creature]]s, so magma natives like [[magma crab]]s and [[fire imp]]s will freely roam through the volcano's interior, and may even leave the crater and roam the surface if they happen to path to it. | Volcanoes do not explode, erupt, nor spew noxious fumes, however, the level of magma within can fluctuate.

On the Region embark map, they are represented as a red raised caret (or circumflex) ({{Tile|^|4:0:1}}), the same symbol as a [[trap|weapon trap]] in-game. On the Local embark map they are represented as two tildes ({{Tile|≈|4:0:0}}), the same symbol that represents magma in-game. On a standard world map, there will generally be only a few volcanoes. |
Volcanoes tend to appear in mountainous [[Igneous extrusive layer|igneous extrusive]] biomes, which means you may be hard-pressed to find [[flux]], [[coal]] or [[wood]]. You won't need it for fuel, but you will still need it for steel making. If you don't feel like searching hundreds of worlds for a volcano next to [[Sedimentary layer|sedimentary stone]] or in a forest, your best bet may be to breach the first cavern for wood (or make tree farms underground once the caverns are opened up), or trade for wood, processed coke or charcoal. A way to use [[advanced world generation]] to mitigate this can be found [https://gaming.stackexchange.com/questions/119308/coal-and-a-volcano-on-the-same-map here]. | Volcanoes tend to appear in mountainous [[Igneous extrusive layer|igneous extrusive]] biomes, which means you may be hard-pressed to find [[flux]], [[coal]] or [[wood]].

− | + | Mining into a warm surface will result in your miner being overrun with the magma before completing the task. Digging a channel beside the warm rock then mining directly into it can safely open a magma flow for redirecting. Another way is to simply channel the warm rock from above. | |
A more complicated, but foolproof method is to tap the tube from one level below, while your miner is protected by an overhead bridge. First, [[channel]] a hole next to the place you want to breach the volcano, creating a hole and a ramp. Then, place a one tile [[magma-safe]] bridge over the ramp. Third, forbid the area the bridge is in -- blocking the area off with a forbidden door, or a contraction, depending on how your fortress works. Then mine the area out from the ramp below. | A more complicated, but foolproof method is to tap the tube from one level below, while your miner is protected by an overhead bridge.
