how would rain, cyclone, and hurricane differ exactly (assuming you mean tropical cyclones)
would hurricanes/cyclones be sideways rain or something
i was tinking something like this and it'll ONLY spawn on a water brick or ocean

not sure how earthquakes would even work unless you just shake everyone's screen
basically that and set velosity so they get smack in the air a bit (no more than 3 bricks height) and a little damage
tornadoes would probably be pretty easy just using particles unless you actually wanted it to fling stuff around
it can start out as that and have a update later so you can turn on brick damage or not
i never got to the hurrican
well here is what i was thinging (spawning)
tornadeos:land only
cyclone:water only
hurrican:both and does x2 dammage
