The access road to the ESO (European Southern Observatory) in Cerro Armazones, was regularly effected by rockfalls after a seismic event with a magnitude of 6.4 Mw in the region of Antofagas.
The observatory needed a safe transit road. Geobrugg was contacted to propose a solution. Geobrugg's Team from Chile visited the site to deliver a probabilistic hazard analysis to the customer. Geobrugg suggested a GBE-100A-R rockfall barrier (without retaining ropes) be installed.
