? > We show maps of observed deformation from InSAR and GPS data that demonstrate an average 1–2 mm/year subsidence rate across New York City (Figure 5), which is consistent with values calculated for post-glacial subsidence across much of the U.S. northeast coast These articles are referencing this study published earlier this month: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2022EF003465 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2022EF00... I’ll have to read it in depth later but seems the researchers modeled the “subsidence” and compared it with GPS data spanning at least a decade.
