Coal mining is one of the most important triggers for earth surface hazards since the coal mining-induced subsidence plays a key role in hillslope instability. However, how earth surface hazards respond spatiotemporally to underground mining operations remains underexplored. A detailed inventory of fissures and landslides was produced using four Unmanned Aerial Vehicle (UAV) photogrammetry surveys from 2020 to 2023 in a coal mining area in Zichang, China. This inventory enables us to annually evaluate the distribution of fissures and landslides and their response to underground coal mining operations. We found that the annual hotspots for newly observed fissures and landslides shifted spatially, corresponding with the yearly expansion of mining operations. The significant suspension of mining operations did not stop the formation of fissures but resulted in a decrease in landslide occurrences. The difference in topographic site effects leads to an uneven distribution of fissures and landslides across all slope segments. Specifically, the fissures clustered on ridge crests, while the landslides clustered on lower slope segments. We also found that fissure strikes were approximately perpendicular to the mining direction both at the scale of the study area and within most of the statistical grids. Furthermore, we estimated the eroded volume of loess in mined-out areas using an empirical relationship derived from UAV-based topography. These results provide additional evidence that earth surface hazards in loess-covered areas can be highly vulnerable to underground mining operations.
