Amsterdam Island (Île Amsterdam) is the most northern volcano on the Antarctic tectonic plate. The island is part of the French Southern Territories. It contains trees and an active volcano.
Amsterdam Island lies on the southeast Indian Ocean Ridge. The ridge is transected by oblique submarine valleys with a NNW orientation thought to be transform faults. The Gallieni Rise, which lies northeast of Amsterdam Is., rises to -365 m.
The area is seismically active with persistent shallow earthquake loci. The rate of sea-floor spreading in this region has been estimated at 3.0 cm/yr
