Identification and Observation of Spatiotemporal Evolution Features of Coalfield Fire Areas Using Landsat Time-Series Decomposition (opens in new tab)

Globally uncontrolled and persistent coal fires cause substantial resource depletion and long-term environmental and safety risks. However, their long-term detection is hindered by complex subsurface dynamics, combustion behavior, and insufficient data from traditional monitoring methods. This study developed an integrated framework for the dynamic characterization of fire hazards. The approach combines time-series decomposition, abrupt change analysis, and robust regression, using Landsat-de...
