Distributed Acoustic Sensing (DAS) is a rapidly emerging technology that uses fibre-optic cables to measure vibrations or temperature changes along the fibre. With DAS, standard telecommunication cables can be turned into seismological antennas, which opens up a plethora of new applications in geophysics and engineering. Some examples include earthquake detection, shallow subsurface characterisation, railroad monitoring, and even weevil infestation control. In this talk, I will explain how DAS works and show a few interesting applications of DAS in seismology and beyond. Then, I will change gears a little bit and show how we can combine DAS, array seismology, and some Deep Learning to monitor traffic in cities.
