Applications
- 6.4.1 Damage Proxy Mapping — Generating rapid, spatially exhaustive maps of earthquake-induced structural damage by differencing pre- and post-event SAR imagery to guide the first 72 hours of emergency response.
- 6.4.2 Building Collapse Detection — Using multi-pass SAR coherence and optical change detection to pinpoint collapsed structures within hours of a major earthquake, guiding search-and-rescue teams to the highest-priority sites.
- 6.4.3 Liquefaction Hazard Mapping — Using satellite SAR coherence and optical data to map ground susceptibility to liquefaction before and immediately after a major earthquake.
- 6.4.4 Aftershock Risk Modelling — Using satellite-derived surface deformation and stress-transfer maps to forecast the location, magnitude and timing of aftershocks following a major earthquake.
- 6.4.5 InSAR Surface Deformation — Measuring millimetre-scale ground displacement caused by earthquakes using repeat-pass synthetic aperture radar interferometry to map fault rupture, subsidence and uplift.
