An Earthquake is a naturally occurring event in Caves and the Ruins. Earthquakes occur regularly and can even be induced by igniting Gunpowders, Slurtle Slimes, Slurtle Mounds, Snurtles, and Slurtles; using a Telelocator Staff and attacking a Big Tentacle. Earthquakes cause mineral items to fall from the ceiling (making some items renewable), though around 75% are destroyed from shattering when they hit the ground. Each items that fall can be
- or with a 37.5% chance each,
- or (or or ) with a 10% chance each (5% each ),
- or or with a 1.6% chance each.
Falling objects caused by Earthquakes deal 30 damage to players, Mobs, and Walls, but not Bosses. When an Earthquake begins, the camera will shake and the character will give a warning before items start to fall. Each object creates a round shadow on the ground, indicating where it will land. A falling object will cause damage until it has shattered or stopped bouncing. These items can destroy walls and other structures over time. Falling debris will also break existing debris on the ground, such as Rocks, Gems, Gold Nuggets, Nitre and Marble.
Wearing armor will reduce the amount of damage taken from falling debris.
In the Reign of Giants DLC, live Rabbits and Moleworms may fall during Earthquakes in their stunned form. If left uncollected, they will recover and behave as usual: the Rabbits will wander aimlessly (like when they lose their home), flee from the player and certain mobs, and sleep at night (on the surface's time). Moleworms will collect a maximum of 3 debris before wandering around. Unlike their surface counterpart, Moleworms will not create Burrows in the caves, but will do so once they are brought to the surface.
Rabbits and Moleworms do not fall during the Ruins' Earthquakes; only minerals will fall.
Using an Old Bell will also cause Earthquakes.
In Don't Starve Together, earthquakes occur every 1 to 3 days. Explosions shorten the waiting time by an amount of seconds equal to the damage of the explosion (300s for Slurtle, 200s for Gunpowder, 50s for Slurtle Mound and Slurtle Slime, multiplied by the size of the stack).
An earthquake lasts between 10 and 15 seconds during which 5 to 6 objects fall every second.
Telelocator Staff creates a mini earthquake where 5 objects fall at the target location.
- Earthquakes were added in the Underground update.
- The addition of Earthquakes has made all the items listed in the article renewable, aside from Gold Nuggets, Blue Gems, and Red Gems, which were already renewable and were thus made more readily available.
- In the older versions of Don't Starve, Birds in cages, Chester, and presumably Pigs stayed asleep underground even during Earthquakes.
