4 event at the Himalayan front. We interpret this evolution as a slow, progressive increase in seismicity, consistent with a late-stage nucleation process modulated by regional tectonics. Our results are therefore compatible with tectonic loading, and suggest that single-station seismic monitoring, when enhanced by AI techniques, can help identify retrospective seismicity patterns prior to rupture, even in data-sparse and tectonically complex regions.
