| | Description | | Malu Malu Seamount is located at 14¿ 35.5' S, 169¿ 48.6' W and is part of the Samoan Hotspot region on the Pacific Plate. It is 4159 m high with the top at -300 m and the ocean bottom at -4459 m. The seamount is small with a volume of 1970 km3. It is fairly round with slightly irregular edges and has multiple rifts radiating out from a central summit. Malu Malu is connected by a saddle to a seamount to the west and is on a common platform with Muli, Olosega and Mauna. |
