GNSS Comparison & Calibration Status
Continuous GNSS time-series validation was not bundled for this regional subset.
Cumulative Displacement Map
What This Means
- Peak measured ground motion in Karapınar, Konya (Türkiye) 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 23,424 residents live on ground sinking faster than 2 cm per 108 days (and 3,734 residents across 3.10 km2 faster than 5 cm per 108 days, above the 0.65 cm 2-sigma noise floor).
- Infrastructure screening flags Konya - Adana Yolu as the highest-differential segment in this footprint; pair satellite tracking with local leveling or groundwater head checks before field action.
