La Langouste: A former French fishing settlement on Île Saint-Paul, used during seasonal lobster-harvesting operations. Its remains mark the island’s most sustained period of commercial occupation.
Volcanic island: An island formed by volcanic activity, commonly through eruptions that build land above sea level. Île Saint-Paul is the exposed summit of a volcanic system.
Volcanic crater: A roughly circular depression around a volcanic vent, formed by eruptions or collapse. The island’s caldera is often described through its crater-like volcanic structure.
