Distributed acoustic sensing (DAS) is a relatively recent development in the use of fiber-optic cable for measurement ground motion. Discrete sensors, typically using Bragg diffraction grating, have been research and field testing more than 15 years with geophysical applications at least 12 old (Bostick, 2000, summary Keul et al., 2005). However, developments sought to remove need point sensors by fiber itself as sensor (Mestayer 2011; Miller 2012).
