Cumulative Displacement Map

Cumulative LOS displacement (2026-06-26 to 2026-10-12, 8 NISAR L2 GUNW pairs).

What This Means

  • Peak measured ground motion in Jakarta (Indonesia) reached -5.9 cm LOS (-5.5 cm/100d) from 2026-06-26 to 2026-10-12, but low coverage or wide reference spread makes this an indicative estimate.
  • About 87,328 residents live on ground sinking faster than 2 cm per 108 days (and 14,923 residents across 6.67 km2 faster than 5 cm per 108 days, above the 0.66 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.
Calibration & Quality Notice (PROVISIONAL): NISAR data are provisional. Calibration and validation are carried out by the NISAR project (NASA-JPL and ISRO), not by our team.
