Seismic Event Overlay Strategies for Long-Duration Rescues

The 2015 Wujek-Slask rockburst in Poland produced an M4.0 event and forced a rescue that ran past fifty days, with seismic aftershocks reshaping the working zone almost daily. Long-duration rescues like this fail when seismic monitoring stays in a separate window from the mine map. This post covers seismic event overlay strategies for long-duration rescues on EchoQuilt.

On September 18, 2015, an M4.0 rockburst at the Wujek-Slask coal mine in Upper Silesia killed two miners and trapped several more behind a cascade of collapsed workings. The rescue operation ran past fifty days, with continuing seismic activity reshaping the working zone and forcing repeated re-entries on revised geometry (Rockburst Rapid Ground Deformation Wujek Collapse (Springer)). The incident command staff had access to national seismic network data, but the feed ran in a separate analyst window from the mine map, and correlating each aftershock to a specific roof section took minutes they could not spare.
