Ma′unga Terevaka is the largest, tallest (507.41 m (1,664.73 ft)) and youngest of three main extinct volcanoes that form Easter Island. Several smaller volcanic cones and craters dot its slopes, including a crater hosting one of the island's three lakes, Rano Aroi.

While Terevaka forms the bulk of Easter Island, the island has two older volcanic peaks: Poike which forms the eastern headland and Rano Kau the southern. Terevaka last erupted in the Pleistocene and is less than 400,000 years old. Its lava field at Roiho has been dated at between 110,000 and 150,000 years old. Terevaka can be climbed via a trail that starts next to the moai at Ahu Akivi.
Terevaka is the 12th most topographically isolated summit on Earth.[2]

[es] Maʻunga Terevaka
El Maʻunga Terevaka (del rapanui y maorí Monte Terevaka) es un volcán inactivo ubicado en el extremo norte de Rapa Nui y que forma uno de los tres grandes conos que constituyen la superficie de la Isla. Tiene la forma de un cono irregular que ocupa la mayor parte de la Isla y una altura de 511 metros sobre el nivel del mar siendo su cumbre el punto más alto de Rapa Nui. Es el más joven de los tres volcanes principales, teniendo su origen en un proceso eruptivo acaecido hace unos 12 mil años aproximadamente. Su último flujo de lava fue hace unos 10 mil años. Según estos datos, la actividad volcánica que dio origen al Maunga Terevaka terminó de formar el triángulo que es hoy Isla de Pascua.[fr] Maunga Terevaka
