Already for several years it has been suggested that Distributed Acoustic Sensing (DAS) could be a convenient, low-cost solution for Earthquake Early Warning (EEW). Several studies have investigated the potential of DAS in this context, and demonstrated their methods using small local earthquakes. Unfortunately, DAS has a finite dynamic range that is easily exceeded in the near-field of large earthquakes, which severely hampers any EEW efforts. In this talk, I will present a detailed analysis of the dynamic range, and how it impacts EEW: where does it come from? What can we do when the dynamic range is exceeded? And is there still hope for DAS-based EEW systems?
