The Nordic Optical Fiber Sensing Research Infrastructure Hub (Nordic DAS) involves five countries – Finland, Sweden, Denmark, Norway, and Iceland – working collaboratively to enhance seismic monitoring and geohazard assessment using Distributed Acoustic Sensing (DAS) technology. Nordic DAS partners actively contribute to global seismic data exchange and European infrastructures like EPOS, and aim to bring novel data to efficient use of community through utilizing fiber optic cables as seismic sensors. The initiative aims to modernize seismological capabilities by leveraging existing fiber-optic infrastructure for real-time, high-resolution seismic sensing across national borders as well as utilizing fibre-optics in various specially designed field experiments. DAS technology has capacity to monitoring seismic waves not only for seismological research but also for environmental applications and anthropogenic hazards in unforeseen spatial resolution.
Nordic DAS involves six work packages over five years, focusing on infrastructure mapping (WP1), data management (WP2), field experiments and best practices (WP3), training and capacity building (WP4), integration of DAS into national seismic networks (WP5), and stakeholder engagement and dissemination (WP6). The collaboration aligns with strategic objectives to advance fiber optic seismology, promote scientific excellence, and strengthen Nordic competitiveness and regional safety through improved seismic monitoring capacity.
