Mauŋa Terevaka (, ) is the largest, tallest (507.41 m) 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 is the 12th most topographically isolated summit on Earth.
Geography
It accounts for around 80% of the island's surface, and is surrounded by active cliffs and gentle hills with cinder cone formations.{{cite thesis| last = Muñoz Lemu | first = Carolina| title = Geomorfología de Isla de Pascua| type = Bachelor's thesis| publisher = Universidad de Chile| date = 2004| url = https://repositorio.uchile.cl/handle/2250/172875| location = Santiago, Chile| language = es|pages=8–13
Hiking
Terevaka can be climbed via a trail that starts next to the moai at Ahu Akivi. Terevaka's route is considered more physically demanding than the other slopes of the volcanoes of the Heritage Route, and it is classified as intermediate. The route is known to have minimal visibility on days with rain, so it is often shut off.
