A volcanic eruption is a natural disaster in Civilization VI: Gathering Storm that can occur from a Volcano tile and affect surrounding tiles.

Mechanics[]

An active volcano may cause a devastating eruption, which is one of the types of natural disasters. Compared to other disasters, this is maybe the most devastating. It will affect tiles surrounding the volcano (or, on Disaster Intensity settings 3 and 4, tiles up to 2 away from the volcano), and besides the usual disaster damage, the eruption may remove features and even bonus resources. Affected tiles will then acquire the Volcanic Soil feature, which receives more potent yields from future eruptions and also yields which aren't available from other disaster types, like Science Science and Culture Culture.

Volcanic eruptions are the only type of Disaster unaffected by climate change.

Since both Volcanic Soil and Floodplains are terrain features, eruptions will not affect Floodplains as this would "break" rivers. The tiles will not gain Volcanic Soil and will not be fertilized. They can still be pillaged though.

Note that you cannot prevent population loss by not working the tiles near a volcano. Eruption events do not check whether the affected tiles are worked or not. While Liang's Reinforced Materials promotion will protect your districts and improvements in a city, it will not prevent population loss.

Volcanic eruptions can be summoned by a Soothsayer standing next to an active volcano in the Apocalypse Game Mode.

Eruption effects[]

Below is a table of the different damage types that each level of eruption causes. The numbers are the percentage chances each damage may occur. Mount Kilimanjaro, Mount Vesuvius and Eyjafjallajökull are all Natural Wonders and now count as volcanoes which are always active. Mount Kilimanjaro erupts on two different severity levels (Gentle and Catastrophic), while Mount Vesuvius always erupts on Megacolossal level. In general, Kilimanjaro gives low and less valued yields (most likely Food Food, or Food Food and Production Production only) while causing less damage, Vesuvius causes devastating damage but gives a lot of high-valued yields (high chance for Culture Culture, medium chance for Science Science, Production Production and Food Food), and Eyjafjallajökull does a moderate amount of both. Eyjafjallajökull and Vesuvius are the only volcanoes which can confer a Science Science or Culture Culture bonus to the nearby tiles, either passively or through eruptions. Eyjafjallajökull is both the only multiple-tile volcano (with two tiles) and the volcano that can affect the most nearby tiles (it has 8 tiles within 1 tile of itself, and 14 in the ring two tiles away). Eyjafjallajökull is usually surrounded only or mostly by Tundra or Snow, and as such provides useful food to nearby tiles.

Compared to other disaster types yields from eruptions are the best. Of course, this comes with higher devastation, as mentioned above. The table below shows the percentage chance of a tile to gain +1 of the given yield per eruption.

Normal volcano Gentle 35 15 0 0

In-game disaster descriptions[]

Volcano type Severity Description
Normal volcano Gentle People gaze skyward in concern, watching smoke rise from a once-quiet volcano.
Catastrophic People living near the volcano flee as lava and ash blankets the surrounding land.
Megacolossal People flee in terror as pyroclastic flows lash the slopes of the volcano and jets of smoke pour into the sky!
Eyjafjallajökull Catastrophic People must go far out of their way to avoid the huge plume of ash that erupts from Eyjafjallajökull.
Megacolossal Eyjafjallajökull tears open a rift in the earth, as if the goddess Hel herself were escaping from the netherworld!
Mount Kilimanjaro Gentle People and animals view the rising column of ash from Kilimanjaro from miles around, and wonder at the Earth’s fury.
Catastrophic Kilimanjaro roars, and a plume of smoke and ash jets into the sky, as people and animals flee in terror!
Mount Vesuvius Megacolossal Citizens scream in terror and flee towards safety as the pyroclastic wave crashes down the flanks of Vesuvius!
