Investigating the Structural Failures Behind Arecibo's Collapse

The collapse of the Arecibo Observatory's telescope in 2020 is attributed to zinc creep in cable sockets, potentially accelerated by electroplasticity due to electromagnetic radiation, according to a National Academies report. The report suggests that the unique electromagnetic environment of the telescope may have hastened the failure, despite a safety factor above two. The NSF plans to replace the telescope with a science education center and is considering the report's recommendations for future projects.

Unveiling the Causes Behind Arecibo Observatory's Collapse

A new report on the collapse of the Arecibo Telescope suggests that the failure of zinc spelter sockets, which anchored the support cables, was accelerated by a phenomenon called electroplasticity. This effect, potentially caused by electrical currents from the telescope's powerful transmitters, may have increased the plasticity of the zinc, leading to its deformation over time. The report also notes that the collapse might have been initiated by Hurricane Maria, which struck Puerto Rico 39 months prior. The findings highlight a unique failure mechanism possibly specific to Arecibo, warranting further investigation.
