Ahu Tongariki is the largest ahu on Easter Island. Its moai were toppled during the island’s civil wars and in the twentieth century the ahu was swept inland by a tsunami. It has since been restored and has fifteen moai including an 86 tonne moai that was the heaviest ever erected on the island.
Ahu Tongariki is one kilometer from Rano Raraku and Poike in the Hotu-iti area of Rapa Nui National Park. All the moai here face sunset during Summer Solstice.
This ahu is on the south coast of Rapa Nui, close to two previous volcanoes, Rano Raraku and Poike. Poike is one of the three main extinct volcanoes that form Rapa Nui, which last erupted between 230,000 and 705,000 years ago. Rano Raraku is a volcanic crater formed of consolidated volcanic ash or tuff, which compose the carved moai. Indeed, nearly half (hundreds) of the moai are still buried in the slopes of the Rano Raraku, the main moai quarry.
