Subsidence Wave Detection and Its Effect on Egress Routing

InSAR satellites can measure ground subsidence at centimeter-to-millimeter resolution across an entire mine footprint, but the data reaches incident commanders on the scale of hours, not seconds. Subsidence waves inside an active rescue propagate fast enough that egress routing has to react at the timescale of the working shift. Here is how EchoQuilt stitches subsidence detection into live egress routing.

USGS remote-sensing work demonstrates that InSAR satellites measure surface subsidence above mine workings at centimeter and even millimeter resolution, making long-term subsidence characterization practical at the basin scale (USGS Measuring Land Subsidence From Space). The same USGS program documents InSAR's broader role in monitoring and characterizing natural hazards at mines and other infrastructure (USGS Monitoring Hazards With Satellite InSAR). OSMRE and Virginia Tech have also published on enhancing mine subsidence prediction specifically for coal (OSMRE Enhancing Mine Subsidence Prediction), and independent InSAR reviews confirm the method detects short-term fast deformation in active mining districts (InSAR Monitoring Mining-Induced Subsidence (UCA T&UC)).
