Mauŋa Terevaka is the largest, tallest () 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
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was fin ...
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.

The topographic isolation of a summit is the minimum geographical distance, horizontal distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and is ...
