The Maunga Terevaka (or simply Terevaka ) is a 507 meters high extinct volcano located in the northwestern part of Easter Island. It is the largest and youngest of the three main volcanoes on Rapa Nui , which is also known as Easter Island. The other two volcanic peaks are the Poike on the eastern part of the island, and the Rano Kau , situated at the southern parts of Easter landscape.
On the slopes of the Terevaka several smaller volcanoes and volcanic craters can also be found, including crater lakes surrounding the crater Rano Aroi and Rano Raraku . The Terevaka had last erupted in the Pleistocene and is less than 400,000 years old. The age of its volcanic hillside at Roiho is estimated between 110,000 and 150,000 years.
