The year 2021 marks a new chapter in our geophysical society as the concept and practice of environmental, social, and governance rapidly enter our work and daily life. This poses great challenges and also offers new opportunities for geophysical research and applications. Among them, distributed acoustic sensing (DAS) as a measurement technology is gaining popularity for its broad frequency band, high sensitivity, low cost, and dense sampling over long distances.

DAS uses fiber-optic cable as a series of sensors to detect and record external disturbances for active and passive seismic monitoring. Several publications are dedicated to this technology and its...
