Description
Chuangli Jing, with seven colleagues, reports a 2026 radar method that tracks a creeping landslide group in fine time detail. The Xiongba slides on the Tibetan Plateau's edge move without pause and threaten towns below. Satellite radar watches them well but sees only along its beam and revisits too rarely.
The team first turned beam-wise motion into true downslope motion for four named slides. A smart filter then merged passes from two orbit paths, filling the gaps between visits. Sentinel-1 records from 2018 to mid 2024 show all four slides still active. The lead slide crept fastest, near ninety-five millimetres a year on one path. The new filter cut error by about a third versus the standard one and halved the wait between reads. Gravity and river wear drive the creep, with rain as the trigger.
