Piton de la Fournaise
Volcano in Reunion

Piton de la Fournaise (French: [pitɔ̃ də la fuʁnɛz]; 'Peak of the Furnace') is a shield volcano on the eastern side of Réunion island, a French overseas department and region, in the Indian Ocean. It is currently one of the most active volcanoes in the world, along with Kīlauea in the Hawaiian Islands, Stromboli and Etna in Italy and Mount Erebus in Antarctica. The volcano is located within Réunion National Park, a World Heritage Site.
Residents of Réunion sometimes refer to Piton de la Fournaise simply as le Volcan ("the Volcano"). It is a major tourist attraction.
Geology
The uppermost section of the volcano is occupied by the Enclos Fouqué, a caldera 8 kilometres (5.0 mi) wide. High cliffs, known as remparts in French, form the caldera's rim. The caldera is breached to the southeast towards the sea. The eastern flank of the volcano is unstable and is in the initial stages of failure. It will eventually collapse into the Indian Ocean, possibly causing a megatsunami in the event of a cataclysmic debris flow.

Why this record matters
The phrase “volcano in Reunion” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q1049644. VIAF identifies the subject as 170186947. The Library of Congress control number is sh90001343. Authority coordinates are -21.243, 55.707. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
