This section of the supplementary materials provides detailed supplementary figures and data to support the main findings of the article "Uncovering the impacts of depleting aquifers: A remote sensing analysis of land subsidence in Iran" by Mahmud Haghshenas Haghighi and Mahdi Motagh. The figures include: - **Fig. S1**: An overview of the coverage of Sentinel-1 data used to estimate land subsidence in Iran, showing ten acquisition tracks covering the entire country, with circles indicating the 20 most populated cities. - **Fig. S2**: Land subsidence rates across Iran estimated by Sentinel-1 InSAR observations, along with its relation to geology, aquifer outlines, and sedimentary deposits. It includes: - **(A)** Land subsidence rates, with major catchment borders indicated and boxes highlighting affected areas. - **(B)** Surficial geology of Iran, focusing on Quaternary and Tertiary deposits. - **(C)** outlines of aquifers across the country. - **(D)** Sedimentary deposit thickness from a global 1-km gridded dataset. - **Fig. S3**: Major areas affected by land subsidence, corresponding to the boxes in Fig. S2. - **Fig. S4**: Elastic/inelastic deformation ratios, used as a proxy for the relative sustainability of groundwater extraction in different basins and sub-basins. The ratio assumes long-term trends are inelastic and short-term variations are elastic.This section of the supplementary materials provides detailed supplementary figures and data to support the main findings of the article "Uncovering the impacts of depleting aquifers: A remote sensing analysis of land subsidence in Iran" by Mahmud Haghshenas Haghighi and Mahdi Motagh.
