This session focuses on the use of fibre-optic sensing to observe, understand, and manage complex urban systems. Beyond the sensing technologies themselves, it highlights how fibre-optic measurements are integrated into the built environment to support resilient, safe, sustainable, and smart cities.

Topics include, but are not limited to: urban subsurface characterization and ground stability monitoring; earthquake detection, early warning, and urban hazard assessment; structural health monitoring of critical infrastructure such as bridges, tunnels, and buildings; transportation and mobility sensing across rail and road networks; environmental monitoring in urban settings; monitoring of utilities and energy systems, including pipelines and power cables; smart-city sensing using telecommunication fibre networks; multi-physics fibre-optic monitoring; and large-scale data processing, cloud and edge computing, and machine learning for real-time applications.

By bringing together researchers, engineers, and practitioners across geoscience, civil engineering, data science, and urban planning, the session aims to advance the transformative role of fibre-optic sensing for resilient and smart cities.
