Lua Challenge: the Catastrophes plugin

[NiLSPACE]

I tried the Catastrophes plugin on a local Spigot server, and I got to say that I'm not really impressed. The tornado is just one explosion at the start point, then 10-15 explosions in a 0.5 second time-span in a random direction, and then it's gone. Even my tornado plugin was better :|

Then the tsunami is an explosion at the start, and then just a square area of water above it:


Then the volcano is just some lava around the area:


The supernova is just some TNT that is thrown all over the place. A vortex gets some blocks around the area, and then throws it around, and an earthquake makes some explosions in 2-4 lines.

This should be fairly simple to do

PS:
I wanna do the volcano I'm gonna make it into an actual volcano ^^
