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 an Old Bell and attacking a Big Tentacle. Earthquakes cause mineral items to fall from ceiling (making some items renewable), though many are destroyed from shattering when they hit the ground. The items that can fall are:
Falling objects caused by Earthquakes can damage the player, Mobs, and Walls. 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.
Wearing armor will reduce the amount of damage taken from falling debris.
Reign of Giants Edit
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.
- Earthquakes were added in the Underground update.
- The addition of Earthquakes has made all the items listed in the article renewable, besides Gold, Blue Gems, and Red Gems. Those were already renewable, although they are now more readily available.
- In the older versions of Don't Starve, Birds in cages, Chester, and presumably Pigs stayed asleep underground even during Earthquakes.
