What this is. The 26 Aug 2026 surge — a glacier collapse into Tibet's Lhende
valley, a debris dam, and its failure — replayed down the Bhote Koshi and Trishuli as an
operations clock. Drag the scrubber or press play.
Honesty. Solid rings carry reported clock times (source in each popup);
dashed rings are estimated from wave arithmetic between reported anchors and say so.
The corridor line is schematic (node to node), not river hydrography. Flood extents
wait on the Copernicus EMSR927 / Sentinel-1 delineations cataloged in the record.
