Volcanoes spawn after the world generates causing them to spawn 'inside' biomes. This causes floating vines in jungle biomes.
Volcanoes are a source of basalt which can be used in building and decoration in the form of Micro Blocks. Basalt also has a high blast resistance.
Volcanoes are also an ample source of lava. They have a "Magma Chamber" which is filled with lava, similar to the bulb of oil at the bottom of an Oil Well. An efficient way of generating geothermal power is to place a pump on top of the lava shaft and pump the lava into a geothermal generator.
- Not all Volcanoes have Magma Chambers in them.
- Volcanoes will not spawn unless you have Redpower World installed. If you install this patch and then open a previously loaded world, volcanoes will only spawn in newly loaded chunks.
