Introduction
A £5.5 million research initiative funded by Horizon Europe Research and Innovation Action is transforming existing telecommunication fibre optic networks into a powerful sensing platform for natural hazard detection and infrastructure monitoring. Titled Engineering Combined Sensing and Telecommunications Architectures for Tectonic and Infrastructure Characterisation (ECSTATIC), this project aims to revolutionise public safety and structural assessments by leveraging already-installed fibre optic cables across the globe.
Below is an in-depth exploration of the project’s technical components, implementation strategies, and potential industry applications, along with how existing fibre infrastructures and AI-powered signal processing open up unprecedented opportunities for global monitoring.

Background: Fibre Optic Networks as Sensors
Modern telecommunications rely heavily on fibre optic cables to handle massive data transfer at high speeds. Beyond data communication, these same cables hold untapped potential as distributed sensing elements. By detecting minute changes in light transmission and reflection along their length, fibre networks can be repurposed for a wide range of monitoring tasks—especially relevant for detecting seismic or structural disturbances.
Why Now?
Over 5 billion kilometres of fibre already installed worldwide
Minimal extra hardware needed to upgrade existing networks
Rising AI capabilities to process and interpret complex signals in real time

Technical Overview: Core Innovations
Advanced Laser Interrogation Systems
ECSTATIC’s architecture enables high-precision measurements of backscattered signals within fibre cables. Laser interrogation techniques help map any disturbance in the cable’s environment—be it a seismic wave under the ocean floor or minor vibrations in an urban building.
AI-Enhanced Signal Processing
Real-time pattern recognition leverages machine learning algorithms to discern meaningful signals (e.g., tectonic shifts) from ambient noise. This means:
Automated anomaly detection
Proactive alerts for structural deformations
Reduced false positives and improved reliability
Distributed Real-Time Analysis
To convert raw optical data into actionable insights, edge computing nodes near the sensing regions process large data sets locally:
Low-latency detection of critical events
Instant feedback loops for infrastructure safety systems
Reduced data bottlenecks on main networks
Integrated Monitoring Platforms
ECSTATIC’s approach combines multiple data sources (e.g., seismic sensors, environmental data) into a single platform. When integrated with 5G or satellite communication, advanced telemetry becomes possible even in remote locations.

Key Deployment Areas
Underwater Networks
Tsunami Detection: Subsea cables pick up real-time changes in seabed pressure, enabling quicker evacuation procedures.
Seabed Movement Monitoring: Early identification of tectonic shifts that could trigger underwater landslides or earthquakes.
Marine Infrastructure Assessment: Tracks structural integrity for offshore wind farms, oil rigs, and seabed telecommunication lines.
Early Warning Systems
Linking undersea signals to coastal stations helps local authorities coordinate emergency responses, potentially saving lives. Explore more about marine applications and how fibre optics stand up to harsh environments in our article on Fiber Optic Solutions for Harsh Environment Applications.
Urban Infrastructure
Building Structural Health: Detect micro-cracks and deformations in high-rise buildings, bridges, or tunnels.
Underground Asset Condition: Monitor sewer lines, gas pipelines, and water mains for leaks or shifts.
Seismic Activity Detection: Gain high-resolution data on ground tremors, crucial for seismically active metropolitan areas.
Real-Time Data Processing
Edge computing units in cities can locally analyse data from distributed fibre sensors, delivering instant updates to municipal authorities. For more insights into how urban landscapes can benefit from fibre-based tech, see our piece on Smart City Development with Fiber Optics.
Railway Systems
Track Condition Monitoring: Identify rail misalignments, cracks, or damage in real time.
Infrastructure Vibration Analysis: Assess the impact of passing trains on bridges and tunnels.
Predictive Maintenance: Automate maintenance schedules by detecting minor issues before they escalate.
Safety System Integration: Real-time alerts can instantly halt trains or reroute traffic for urgent repairs.
Technical Advantages & Considerations
Infrastructure Utilisation
By leveraging current fibre lines, ECSTATIC avoids laying down massive new networks—keeping capital expenses lower. With broad coverage across continents and undersea routes, the potential for worldwide hazard monitoring grows exponentially.
Key Benefit: Minimal hardware modification plus a quick installation of laser interrogation nodes.
Detection Capabilities
Continuous, Real-Time Monitoring: Fewer blind spots and improved event-response times
High Sensitivity: Sub-millimetre ground shifts or micro-fractures in a pipe can be pinpointed
Early Warning: Gains lead time for natural disasters like earthquakes or tsunamis
