[Bug] Earthquake spell underground crashes modpack server

Observed behaviour

After player casted Earthquake spell in the 2x1 tunnel underground server starts to ticking too high, fps dropped low, ram usage goes high with everyone who stands close to epicenter, chunks stopped generating.

I used to reproduce same thing in singleplayer - same issue.

Expected behaviour

Earthquake spell will casts with the same effect like on surface, and does not crash server when used underground

Steps to reproduce

  1. Dig staircase-like tunnel 2x1 straight under the ground to the y coord below 30 or even under 0
  2. Turn around facing to the place where are you come from
  3. Turn your vision up while beign under the ground in the tunnel
  4. Cast spell Earthquake 3+ level on the blocks that in your sight
  5. Do it 1-2 times and wait until spell time goes off
  6. Check your FPS rate and RAM usage

I've done it in singleplayer and on the server, crash happened in both cases

Server Type

Dedicated Server

Lines 140 to 147 in b5e8388

protected void createTremorBlock(BlockPos blockPos, float impulseStrength) {
var fallingblockentity = new VisualFallingBlockEntity(level, blockPos.getX(), blockPos.getY(), blockPos.getZ(), level.getBlockState(blockPos), 20);
fallingblockentity.setDeltaMovement(0, impulseStrength, 0);
level.addFreshEntity(fallingblockentity);
if (!level.getBlockState(blockPos.above()).isAir()) {
createTremorBlock(blockPos.above(), impulseStrength);
}
}

shouldn't there be a cap on how many recursive calls this can make (in addition to the air check)?
like a max. height (from the origin)
