Natural Disasters: Cataclysm

Natural Disasters: Cataclysm turns Minecraft into a dynamic disaster survival
experience. Instead of playing a simple particle effect, every event has its own
warning phase, cinematic atmosphere, physical forces, gameplay consequences and
configurable interaction with the world.

Events are selected according to the player’s environment. Ocean threats stay in
the ocean, cave disasters target underground explorers, altitude events threaten
elytra users, and the Nether and End have their own cataclysms. The natural event
director prevents incompatible random disasters from starting at the same time.

Back up important worlds. Many disasters can permanently break or place
blocks. Terrain damage can be disabled or limited in the configuration files.

More than random destruction

• Weighted categories make minor events more common and extreme cataclysms rare.
• Earthquakes use decimal magnitudes up to M10.0 and can create major fissures.
• Tornadoes and hurricanes use intensity categories with visible wind, debris,
  suction, lift and controlled player launching.
• Ocean events create currents, waves, temporary or permanent flooding and
  physical effects on boats and entities.
• Cave events use falling blocks and connected underground spaces to collapse or
  flood tunnels.
• High-altitude events interfere with elytra flight and punish exposed players.
• Nether and End events use dimension-specific terrain, atmosphere and hazards.
• Some disasters can intentionally trigger another event, such as an undersea
  earthquake producing a tsunami or a magmatic rupture producing a lava surge.

Survival tools and controls

The mod includes a dedicated creative tab with unique 32×32 invoker items for
every disaster. It also adds a seismic analyzer for live earthquake readings and
a craftable seismic alarm that warns nearby players before a scheduled quake.

Server operators can use /disaster commands to test specific levels, radii and
durations or stop all active events. Naturally generated events do not require
commands.

Configuration and performance

Natural Disasters: Cataclysm includes separate common and client configuration
files. Server owners can control random event frequency, terrain damage, entity
effects, block budgets and disaster-specific limits. Players can reduce camera
movement and particle density through the client configuration.

Disasters do not intentionally force-load chunks. Events stop or suspend their
world work when the required area is no longer loaded or observed.
