TFC Volcanoes
by Verph
TFC Volcanoes adds volcanic activity to TerraFirmaCraft, with eruptions, tremors and new minerals tied to lava and hot springs.
What it does
Volcanoes extend TerraFirmaCraft by strengthening magmatic processes near the surface, where geothermal flux feeds eruptions, earthquakes, tremors and pyroclastic bombs. Many new mineral types appear around both lava and hot springs, including sulphur, ammonium chloride and saltpeter, and some of them can be pulverized into fertilizers. Deposits near pools and springs reintroduce well-known ores that TerraFirmaCraft players may recognize from earlier versions.
Lava behaves differently depending on the local rock type, and the behavior can be configured. Certain rock types make lava spread slowly over short distances, while other conditions let it travel much farther. Throwing moist items into lava produces reactions of its own. The mod requires TerraFirmaCraft and runs on client and server, so the server and every player need it. Builds target Forge and NeoForge for 1.20.1, 1.21 and 1.21.1, and the code is licensed under the BSD 2-Clause License, which means it is not open source.
Key features

How it compares
TFC Eratosthenes is released under the GNU General Public License v3.0 or later and is open source, with builds for 1.20.1 – 1.21.1. It is server required with an optional client, so the server must run it while players may leave it out. TFC: Real World is client and server under the MIT License, not open source, and reaches further back with files for 1.18.2 – 1.21.1. Volcanoes stays on the same 1.20.1 – 1.21.1 range and the same environment as More Lava TFC, which is also not open source but uses the MIT License.
