Moaï : ces mystérieuses sculptures La grande majorité des Moaï est issue de la carrière des pentes du volcan Rano Raraku. Ce sont près de 200 moaï de toute taille qui ont été sculptés et souvent extrait des flancs du volcan. Le tuf volcanique est une roche plutôt tendre et relativement légère que les Rapa Nui ont choisi d’exploiter pour la construction de leurs moaï. En effet, les Rapa Nui n’avaient pas d’outils en fer et ne travaillaient la roche qu’à l’aide d’outils fabriqués dans une pierre plus dure, c’est pourquoi ce tuf se prêtait mieux que d’autres roches à la sculpture. Quelques-uns des moaï ont été taillés dans un basalte beaucoup plus dur. Le Te Tokanga est la carrière de scories rouges d’où ont été extraits les pukao, la coiffe des moaï. Cette roche tendre et rouge reste lourde. Les pukao pèsent entre 9 et 12 tonnes ! Inspiré d’un article de Jacques-Marie Bardintzeff, Michèle et Sylvain Chermette.
