it passes the threshold we say, ‘Oh, something is happening here.’” In recent years, new technologies have greatly improved the accuracy of these map models, and that progress continues to grow. Interferometric synthetic aperture radar (InSAR), light detection and ranging (LiDAR), ground-penetrating radar (GPR), and remote sensing can help scientists collect more data, more frequently. While around for decades, today “we can use InSAR to identify portions of the landscape that are actually in motion slowly,” Clague said. Dr. Matthieu Sturzenegger, P.Geo., P.L.Eng., a senior engineering geologist with BGC Engineering, noted InSAR “allows [engineers and geoscientists] to detect millimetre-type displacements, which would allow us to see some stuff that we may not have been able to see before.” Advancements in satellite technology (and deployment) have significantly increased the frequency at which this InSAR data can be collected. Synspective, a SAR satellite data provider, successfully demonstrated daily InSAR image acquisition in 2024, showing that daily monitoring is technically feasible under certain conditions. These high-frequency observations are particularly valuable for disaster prediction, construction site safety, and rapid response scenarios, but their availability is currently limited to certain regions and platforms. LiDAR uses laser pulses to measure distances
