Distributed acoustic sensing (DAS) is rapidly becoming a transformative technology for seismological applications, leveraging the widespread and expanding global network of telecommunication fibers. Its effectiveness lies in its ability to convert standard fiber-optic cables into dense seismic arrays. However, the advantages of DAS come with challenges—most notably, the massive data volumes generated, often reaching tens of terabytes from a single deployment, and the unique strain-based measurements that require new data analysis paradigms.
