Njord Seminar with Martijn van den Ende

Martijn van den Ende (Université Côte d'Azur): Earthquakes, fibre-optic cables, and a zebra: intelligent solutions for tomorrow's seismology

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 what we can do when we combine DAS with Machine Learning. More specifically, I will detail how we can leverage the two dimensions of DAS for coherence-based signal denoising, and for solving challenging deconvolution problems in traffic analysis.
