Enhanced Landslide Susceptibility Mapping in Southwest Cyprus Using InSAR Technology
Landslides are a significant geohazard in many parts of the world, particularly in regions with rugged topography and complex geological conditions. Southwest Cyprus is no exception, with over 2,500 landslide incidents recorded annually. These events pose threats to communities, infrastructure, and ecosystems. However, until recently, traditional methods of mapping landslide susceptibility fell short in addressing the dynamic and unpredictable nature of landslide risks.
​
Thanks to Interferometric Synthetic Aperture Radar (InSAR) technology, the approach to landslide susceptibility mapping is undergoing a revolution. By providing seasonally updated maps that incorporate real-time surface deformation data, InSAR has made it possible to tackle this geohazard more effectively than ever before.
How InSAR Technology is Revolutionising Landslide Susceptibility Mapping
Key Benefits of InSAR-Based Landslide Susceptibility Maps
1. Real-Time Monitoring
Unlike traditional methods, InSAR provides continuous data, revealing shifts in the Earth's surface as they occur. This real-time monitoring is invaluable for capturing dynamic changes in landslide susceptibility, particularly during periods of heavy rainfall or seismic activity.
​
2. Seasonal Updates
InSAR data can be combined with other datasets to create maps that are updated seasonally. These updates integrate the latest environmental conditions, such as changes in soil moisture, slope stability, and rainfall patterns, ensuring that the maps remain accurate and relevant.
​
3. Predictive Power
By layering InSAR data with other information—such as hydrogeological, topographical, and geotechnical data—analysts can identify trends that predict future landslide activity. This predictive capability is crucial for proactive risk management.
​
4. Cost-Effectiveness
InSAR eliminates the need for extensive fieldwork, reducing the costs associated with traditional mapping methods. This makes it a scalable solution for large areas like Southwest Cyprus, where geohazards are widespread.
​
5. Enhanced Safety and Resource Allocation
The detailed and dynamic insights provided by InSAR-based maps enable authorities to allocate resources more effectively. High-risk areas can be prioritised for interventions such as slope reinforcement, drainage improvement, or community evacuation planning.
The adoption of InSAR technology for landslide susceptibility mapping represents a major leap forward for geohazard management in Southwest Cyprus. By combining high-precision satellite data with hydrogeological, topographical, and geotechnical insights, this approach has transformed static, outdated maps into dynamic, actionable tools.
For a region as vulnerable as Southwest Cyprus, the ability to monitor and predict landslide risks in real time is invaluable. This innovative methodology not only enhances safety but also supports sustainable development by enabling more effective use of resources.
