Cratère Antonelli Crater

Cratère Antonelli is a volcanic crater on Île Amsterdam in the southern Indian Ocean, recorded at the supplied coordinates. It is one of several small summit and flank craters on the island’s volcanic massif and is part of the island’s volcanic landscape.

The feature is a geologic vent formed by volcanic activity; visitors do not normally reach it because Île Amsterdam is a remote French Southern and Antarctic Lands possession with restricted access for conservation and scientific purposes. No public infrastructure or visitor facilities are present on the island.

The crater exists as part of the central volcanic complex of Île Amsterdam, which consists of lava flows, scoria cones and collapsed vents formed by relatively recent volcanic episodes in geological terms. Over time the island’s volcanic features have been modified by erosion and vegetation but remain clearly volcanic in origin.

Geographically the crater sits on Île Amsterdam (latitude and longitude as given), a small subantarctic island administered by France and located in the southern Indian Ocean.

• Access: Located on Île Amsterdam, which is part of the French Southern and Antarctic Lands; the island is a protected nature reserve with strictly limited public access.
