The historical existence of [[Volcanism|volcanic activity]] in the Massif Central is somewhat visually evident. Volcanic eruptions have happened for at least 150,000 years, but all volcanoes there have been dormant for at least 112 years.{{citation needed|date=August 2022}} Volcanic activity in the area is the direct cause of the many thermal springs that exist in and around Vichy. |

The famous [[mineral spring]]s in Vichy are rich in trace elements such as [[lithium]] and [[fluorine]], and high in [[sodium bicarbonate]].{{cite report |title = Nomination of the Great Spas of Europe for inclusion on the World Heritage List | publisher = United Nations Educational, Scientific, and Cultural Organization |url = http://whc.unesco.org/en/list/1613/documents/ |access-date = 21 August 2021}} The temperatures of the spring range from 73 |

In total, about 289 springs have been charted in Vichy and its surroundings. These springs are derived from infiltration through [[Oligocene]]-period sedimentary rocks, part of the [[Limagne Graben]] collapse basin. |
