InSAR + Geotechnical Engineering for Tailings Dam Safety
Geofem
In geoscience and civil engineering, the intersection of satellite remote sensing technologies and geotechnical engineering represents a significant leap forward in enhancing the safety of tailings dams. This confluence of disciplines, particularly through the application of Interferometric Synthetic Aperture Radar (InSAR), promises to revolutionise the conventional paradigms of dam safety measures and dam failure prevention. […]
Case Study: The Çöpler Gold Mine Disaster – Satellite Remote Sensing, Soil Moisture, and the Lessons for Mining Safety
Geofem
Executive Summary On February 13th, 2024, the Çöpler Gold Mine in eastern Türkiye experienced a catastrophic failure of its heap leach pad. Approximately 10 million cubic metres of material mobilised rapidly in a high-velocity flowslide, devastating infrastructure and resulting in nine confirmed fatalities. This event underscored the urgent need for advanced monitoring techniques in mining—particularly those […]
Tailings Pond Bathymetry and Soil Moisture Detection by Satellite
Geofem
You may be aware of satellite technology solutions such as InSAR being deployed by mining companies to monitor and assess Tailings Storage Facilities (TSFs), offering unprecedented insights into dam stability and failure risk. But what you may not know is how specialised applications in satellite-derived bathymetry and soil moisture detection can bolster these insights, giving […]

Çöpler Mine Landslide: Tackling Landslides with InSAR
Geofem
Introduction On February 13, 2024, a catastrophic landslide occurred at the Çöpler Gold Mine in Turkey’s eastern Erzincan province causing significant environmental concerns. This incident highlighted critical gaps in traditional monitoring systems and raised important questions about how advanced remote sensing technologies could have potentially predicted—and possibly prevented—such a disaster. The Çöpler Mine Incident: What […]
Monitoring Mining-Induced Subsidence with InSAR: Lessons from Douglas Park
Geofem
Longwall mining operations bring undeniable economic benefits – but also a persistent challenge: mining-induced subsidence. Over time, the ground above mined areas can sink, disrupting ecosystems, damaging infrastructure, and putting community trust at risk. Submit your area of interest for a data search. Why Mining-Induced Subsidence Monitoring Matters In regions like Douglas Park, New South […]
Tailings Dam Monitoring: Traditional Instruments vs InSAR
Geofem
In the realm of geoscience, the monitoring of tailings dams is a critical aspect of ensuring environmental safety and structural integrity. As the mining industry continues to expand, the need for effective and reliable monitoring techniques becomes increasingly crucial. Two primary methods are employed for this purpose: traditional monitoring techniques and the more advanced Interferometric […]
When Tailings Dams Collapse (And What Can Be Done to Prevent It)
Geofem
Dawn broke over the small mining town of Jagersfontein in South Africa’s Free State Province on September 11, 2022. For years, this historic diamond mining region had lived in the shadow of enormous tailings dams—massive structures holding back millions of cubic meters of mining waste. On this particular Sunday morning, residents went about their usual […]
