How to Force an Earthquake?

[GrandmasterSen]

Hi there, I am editting the Old Bell mod for my own use and trying to restore the behavior of causing an Earthquake when used in caves....

Right now I am using this snippet...
 

local world = TheWorld
if world:HasTag("cave") then
  if world.components.quaker then
    world:DoTaskInTime(2, function(world)
    world.components.quaker:ForceQuake(5)
    end)
  end
else

But it does nothing.  Anyone have a solution, please?
