 Approximate surface projection of Boomerang Seamount (blue outline). Nearby mantle Bouguer Abnormality has been mapped in red shading to indicate likely current hotspot plume location.[1] Also mapped is approximate outline Amsterdam Saint Paul Plateau (brown), nearby subsurface transform faults (grey), fracture zones (orange), their probable extensions (light orange) and plate boundary (white, in this case the Southeast Indian Ridge) as referred to in text of article.[2] | |

The Boomerang Seamount is an active submarine volcano, located 18 km (11 mi) northeast of Amsterdam Island, France. It was formed by the Amsterdam-Saint Paul hotspot and has a 2 km (1.2 mi) wide caldera that is 200 m (660 ft) deep. Hydrothermal activity occurs within the caldera.[3] The sampled rocks are basalt and picrite basalt.[4]
