 From NetHack 3.0.0 to [[NetHack 3.4.3]], the drum of earthquake is subject to a few [[Bugs in NetHack 3.4.3|notable bugs]]:

 The drum of earthquake is much more useful when known to the hero, and can be used to awaken already-hostile monsters from a longer distance: [[Rogue]]s in particular can attract the attention of their [[quest nemesis]], the [[Master Assassin]], on the [[Rogue quest]]'s goal level by applying the drum while standing at the bottom right square of the left section&mdash;the hero is normally blocked off from the nemesis by [[no-teleport]] restrictions and undiggabble walls, but the earthquake effect will wake him up immediately and cause the [[covetous]] Master Assassin to warp to the hero's location.
-The drum also has a niche application for flying or levitating heroes to try and slow down pursuing hostiles, especially in open areas such as the [[Big Room]], and has a somewhat-less-niche use in attracting the [[Wizard of Yendor]]'s attention in the late game stages without having to climb the [[Wizard's Tower]]. Though in theory this can also slow down monsters pursuing a hero on the Astral Plane, the risk of angering a [[high priest]] may cause serious complications upon reaching one of the high altars, and it will have a lesser effect on any covetous monsters while doing nothing against flying monsters such as the [[Riders]].

 A drum of earthquake with no charges can often prove more useful than a regular leather drum since it does not deafen the hero or abuse their wisdom, and the lower range of the noise it produces makes it less likely to affect monsters outside of the hero's range of vision. If all else fails, the item is useful [[polypile]] fodder for trying to produce other magical tools or instruments.
