 Abstract: To determine crustal properties distribution, seismic source processes, and wave propagation mechanisms, the acquisition of dense seismic and ground motion datasets is required (e.g., Jousset et al. 2018). Seismic and ground-motion datasets are typically acquired measuring acceleration, velocity (e.g., geophones and broadband sensors), or position (e.g., GNSS sensors) with individual sensors located in a favorable geometry. A high-resolution image of the subsurface, thereby, requires a dense spatial coverage of sensors. In recent years, fiber optic sensor technologies have been increasingly used for seismic applications. Different acquisition strategies have been applied to measure the subsurface deformation: measurements at a single point using specially engineered fiber optic point sensors, quasi-distributed measurements along an optical fiber with an array of point sensors, or fully distributed, where deformation is detected using interaction of light with the molecular structure of the fiber itself. We will consider fully distributed technologies in the following, only.
