Easter Island (Island Week 2)

Thursday, 30th August 2007 by

(It’s Island Week 2 here at GSS, which means we’ll mostly be posting about Islands. For about a week.)

Located in the south eastern Pacific Ocean, almost four thousand kilometers from continental Chile, Easter Island - or locally Rapa Nui - is one of the world's most isolated inhabited islands1, as well as one of the world’s most fascinating archaeological sites.

The human history of Easter Island probably began somewhere between AD 300 and 1200 when people from the islands west of here landed with the tools, animals and provisions to stay for good. Although only 171 km2 in area, at the time Easter Island had extensive forests, and the volcanic craters held drinking water - which is an important feature on an island with no rivers.

Somewhere between AD 1000 and 1500, the Rapanui began a period of frantic construction of enormous stone statues - the Moai, for which Easter Island is world famous today. These enigmatic figures represented the islander's deified ancestors, and were mostly placed near the coast, with their backs to the sea.

Moai are hewn from the island's volcanic rock2, and the largest Moai erected was almost 10 metres high and weighed 75 tonnes; their production and transportation is considered a remarkable accomplishment.

887 Moai have been identified to date, however only a quarter ever made it to one of the coastal Ahu platforms - nearly half of all Moai remain at a single site called Rano Raraku, the volcanic crater where 95% were originally carved. The landscape is littered with 397 Moai - some half-finished, some semi-submerged in the earth through erosion, and others never even detached from the rock.3

By the time explorers arrived here in the 18th Century, the forests of the island had completely disappeared. It's unknown whether or not the Rapanui had used all the trees in the construction of the Moai, or if some other ecological factor was involved, but either way the islanders were now trapped - there was no longer any wood available for making seaworthy canoes.

After this things began to go rapidly downhill for the inhabitants of Easter Island. There followed a period of tribal wars, raids by Peruvian slavers, epidemics of European diseases, and the conversion of the entire island into a sheep farm. During this period much Rapa Nui culture was lost forever, nearly all of the Moai were deliberately toppled (probably by warring tribal factions), and by the late 19th century only 111 of the indigenous people remained alive.

Somehow, against all the odds, today there are several thousand descendants of the surviving 111 Rapanui living on Easter Island - which now has sustainable forestry and the longest runway in Polynesia (having been extended to function as an emergency landing place for the U.S. Space Shuttle). The Moai have returned too - many have been re-erected on their Ahus around the island and one has even been given new eyes.

  1. Featured earlier in the week, Easter Island's nearest inhabited neighbour is Pitcairn Island - 1,931 kilometers west of here. ↩︎

  2. Whilst most Moai were carved from easily worked tuff, Hoa Hakananai'a is one of just ten Moai that were carved from much harder basalt↩︎

  3. The biggest Moai ever carved also remains on the slopes of Rano Raraku, which at 21.6 metres tall and around 270 tonnes was probably impossible for the Rapanui to move. ↩︎
