We analyse five NASA–ISRO Synthetic Aperture Radar (NISAR) pixel-offset pairs spanning the 26 August 2026 Bhote Koshi ice–rock avalanche, Nepal. The last pre-event pair estimates 0.96 m median displacement over 24 days, with its mean vector 18° from the topographic fall line. No pre-event interval exceeds the 95th percentile of spatial comparison distributions for displacement or directional coherence. We report rankings rather than detections. The co-event field lacks directional organisation in both processing chains. Available interval averages do not establish precursory acceleration and cannot isolate motion during the final week before failure.
