Cumulative Displacement Map
What This Means
- Ground in Kashmar subsided up to -6.2 cm LOS (-5.2 cm/100d) between 2026-06-19 and 2026-10-17, consistent with active seasonal compaction.
- About 19,367 residents live on ground sinking faster than 2 cm per 108 days (and 88 residents across 4.58 km2 faster than 5 cm per 108 days, above the 0.45 cm 2-sigma noise floor).
- No local GNSS or canal-tilt overlay is bundled for this subset; field inspection and local piezometer records are needed to confirm infrastructure impacts.
