In a groundbreaking study published in ‘Remote Sensing’, researchers have harnessed the power of the European Ground Motion Service (EGMS) to assess ground vulnerability in the Preveza Region of Greece. This research, led by Eleftheria Basiou from the Department of Geology and Geoenviroment, National and Kapodistrian University of Athens, provides critical insights into ground deformation and its implications for local infrastructure, a topic of increasing importance for industries, particularly in the mining sector.
The study utilized data from the Sentinel-1A and Sentinel-1B satellites, which are equipped with C-band Synthetic Aperture Radar (SAR) technology. This innovative approach allows for millimeter-scale measurements of ground motion, essential for understanding both anthropogenic and natural hazards. The research specifically focused on ground displacement from 2018 to 2022, revealing significant variations in East-West and vertical mean velocity displacements across the region. For instance, the East-West Mean Velocity Displacement ranged from 22.5 mm/y to -37.7 mm/y, while the Vertical Mean Velocity Displacement fluctuated between 16 mm/y and -39.3 mm/y.
“The findings underscore the critical need for ongoing monitoring of ground movement, particularly in areas where infrastructure is at risk,” Basiou emphasized. This is particularly relevant for the mining sector, which often operates in geologically unstable regions. Understanding ground motion can help mining companies mitigate risks associated with subsidence and other geological hazards, ultimately protecting their investments and ensuring operational safety.
The research identified vulnerabilities in various critical infrastructures, including 21 school units, two health centers, a hospital, four bridges, and a dam. Notably, the area of Kanallaki exhibited significant vertical displacement linked to the 2020 earthquake, highlighting the urgent need for structural assessments of nearby schools and health facilities. Basiou noted, “The implications of ground motion on infrastructure stability are profound, especially in regions susceptible to seismic activity.”
Moreover, the study revealed that the dam and bridges along the Ionia Odos are also experiencing considerable accumulated displacements, raising alarms about their structural integrity. This information is vital not only for public safety but also for industries reliant on these infrastructures, including mining operations that may depend on the transport of materials via these routes.
The implications of this research extend beyond immediate safety concerns. By integrating EGMS data with geospatial information, stakeholders can make informed decisions to enhance the resilience of critical infrastructures. This proactive approach can lead to the development of risk-reduction plans that not only safeguard public assets but also bolster the operational continuity of industries, particularly in the resource extraction sector.
As the mining industry grapples with the challenges posed by climate change and geological instability, studies like Basiou’s provide a roadmap for navigating these complexities. The ability to monitor ground motion with unprecedented accuracy can empower mining companies to adapt their operations and minimize potential disruptions.
In an era where data-driven decision-making is paramount, this research serves as a reminder of the importance of integrating advanced monitoring technologies into risk management strategies. As the mining sector continues to evolve, the insights gleaned from studies like this will be instrumental in shaping future developments, ensuring that critical infrastructures remain resilient in the face of natural and anthropogenic challenges.
