This Tsunami
by B_Kirill
With This Tsunami installed, a player can fill a bucket with one of 48 fluid types and pour it out as a spreading tsunami in the world.
What it does
Each tsunami type is a bucket item with its own behavior, including slow, fast, lava, cold, toxic, TNT, oil, acid, ender, slime and liquid nitrogen variants, along with random and void buckets. Tsunamis spread across terrain and can be stopped by a game rule that prevents further spreading.
The mod exposes several game rules that adjust its behavior. One rule lets tsunamis break certain blocks such as doors, glass and foliage. Another makes an oil tsunami chain-detonate when its block is destroyed by an explosion. A third allows unsafe tsunamis, which can cause severe performance impact or irreparable destruction of a world. These rules are off or on by default as listed in the mod's settings.
The mod runs on the client and the server, so both need it installed. It is published for Forge and NeoForge across 11 release versions, 1.12.2 – 1.21.1, under All rights reserved, and it is not open source. Files exist for 1.20.1 on Forge and 1.21.1 on NeoForge, the latest of which are dated 2025-06-29 and 2025-08-30.
Key features
48 tsunami types
Each bucket type produces a tsunami with distinct behavior, from slow and fast flows to toxic and radioactive ones.
Spread control
A game rule stops tsunamis from spreading, and setting it back resumes spreading until the tsunami block is updated again.
Block damage rule
An optional rule lets tsunamis break doors, glass and foliage, which changes how destructive a tsunami is.
Explosive chain reaction
Blowing up an oil tsunami block while the oilTsunamiChainDetonation gamerule is set to true starts a chained explosion across the connected oil.
Performance considerations
The author advises against creating many tsunamis at once, because the load grows quickly on large numbers and high render distances.

What the author says
Here you can suggest your own kind of tsunami for the new version of the mod. Performance:\ Although this mod is well-optimized for versions 1.16.5+, tsunamis increase the load on the game exponentially. Even on powerful hardware, you should not expect a lag-free experience when creating 20 tsunamis at once with a…
