  • A new study warns that rising sea levels could threaten Easter Island's iconic moai statues and other cultural sites by the end of this century.
  • The research, published in the Journal of Cultural Heritage, specifically highlights that the 15 monumental figures at Ahu Tongariki could be inundated by powerful seasonal waves.
  • Lead author Noah Paoa and his team used a high-resolution "digital twin" of the island's coastline to model future wave impacts, predicting waves could reach Ahu Tongariki as early as 2080.

  • The study urges proactive measures such as coastal armoring, breakwaters, or even relocating the monuments to prevent irreversible damage to these globally significant heritage sites.
