AbstractThe possibility of using a pre-existent fiber optic network as Earth’s nervous system to monitor deformations with high sensitivity across the world in real time is overviewed. The potential and results on the use of distributed acoustic sensing (DAS) as a tool for seismology are discussed, with emphasis on the recent technology of chirped-pulse DAS.
