[00:14:07:368] [CLIENT BOUND] - LevelEventPacket(type=PARTICLE_DESTROY_BLOCK, position=(15.5, -60.5, 1.5), data=10598)
[00:14:07:398] [CLIENT BOUND] - UpdateBlockPacket(flags=[NEIGHBORS, NETWORK], blockPosition=(15, -61, 1), definition=UnknownDefinition[runtimeId=11881], dataLayer=0)
When destroying blocks in creative mode, the server
receives PlayerActionPacket(runtimeEntityId=16, action=DIMENSION_CHANGE_REQUEST_OR_CREATIVE_DESTROY_BLOCK, ...).
The data field in LevelEventPacket(type=PARTICLE_DESTROY_BLOCK, position=(3.5, -60.5, -1.5), data=10598) actually
refers to the block but uses the old network ID (it's unclear why the new BlockStateHash is not used).
PARTICLE_DESTROY_BLOCK refers to the particles and sound when a block is completely destroyed (drops).
Sending this LevelEvent to the client will trigger particles and sound.
Note: 50342246 and 10598 are the BlockStateHash and the old network ID of minecraft:grass_block respectively.

The data field in LevelEventPacket(type=BLOCK_UPDATE_BREAK, position=(15.0, -61.0, -8.0), data=3640) indicates the
time required to mine.
The formula is
\[
time = \frac{6553.5}{\text{required mining seconds}}
\]
The data field in LevelEventPacket(type=PARTICLE_CRACK_BLOCK, position=(3.5, -60.5, -1.5), data=50342246) indicates
the block's BlockStateHash.
PARTICLE_CRACK_BLOCK refers to the particles coming off the block surface during breaking.
