Abstract

Paranal Observatory is located near Antofagasta city, northern Chile, one of the most seismic regions in the world. Telescopes and scientific instruments are permanently exposed to the risk of damage caused by earthquake events, ranging from optical misalignment to complete cease of operations. A seismic monitor is installed on the site, providing real-time data to make rapid post-earthquake assessments of expected damage and determine the areas, type and level of inspections to be carried out before continuing with the regular operations. With more than ten years of seismic data and its correlation with reported issues, we show that the inspection and recovery strategy can be defined taking into account the characteristics of the seismic event and according to system-dependent criteria.
