easter island 3d map carved statues

Researchers from Binghamton University, at the request of an indigenous community group on Easter Island, have created a high-resolution 3D model of the Rono Raraku quarry, where 95 percent of the island's moai statues were carved. Using drone flights and over 11,000 overlapping photographs stitched together via photogrammetry, the model documents the quarry in unprecedented detail, including 133 quarried voids, 400-plus unfinished moai, and evidence of 30 distinct clan-based carving areas. The model is freely available online and was motivated by a 2022 wildfire that threatened the site.

massive moai statues walked to platforms easter island new study

A new study in the Journal of Archaeological Science by archaeologists Carl Lipo of Binghamton University and Terry Hunt of the University of Arizona proposes that the 92-ton moai statues on Easter Island, Chile, were transported in a vertical position using ropes to “walk” them onto their stone platforms. The research combines three-dimensional modeling, field experiments with a scaled replica, and analysis of 62 abandoned statues along ancient roads, finding that wider bases and a forward lean of 6–15 degrees enabled a rocking motion that allowed a team of 18 people to move a statue 328 feet in about 40 minutes.

22 stone blocks alexandria ancient lighthouse seafloor

A team from the French National Center for Scientific Research has lifted 22 massive stone blocks from the Lighthouse of Alexandria from the seafloor, 30 years after the remains were first discovered in Egypt. The blocks include monumental door lintels, jambs weighing 70 to 80 tons, a threshold, large base slabs, and parts of a previously unknown pylon with an Egyptian-style door from the Hellenistic period. Each block will be scanned and studied to add to a digital collection of over 100 blocks already digitized, aiming to construct a virtual model of the lighthouse. The excavation was supervised by archaeologist Isabelle Hairy and conducted under the Egyptian Ministry of Tourism and Antiquities, with support from La Fondation Dassault Systèmes and French documentary company GEDEON Programmes, which filmed the work for a 90-minute documentary.
