•Sentinel-1 PS-InSAR well captured the tunneling-induced subsidence in reclaimed land.•Dewatering during vertical shaft excavation and TBM tunneling caused subsidence.•Localized subsidence trough mapped showing velocity over 40 mm/yr in reclaimed land.•Sentinel-1 PS-InSAR outcomes agree well with le...
