Service Description: Subsidence database layer: this point layer shows the location of the subsidence occurrences compiled from previous global reviews, nationwide studies and published case studies before 2018. Countries without GW data layer: this polygon layer with white hatched polygons indicate countries where groundwater data is unavailable, and the potential subsidence only includes information on the global subsidence susceptibility. Global Subsidence Hazard layer: the global subsidence hazard map indicates the probability of land subsidence due to groundwater depletion classified in six intervals from very low (VL) to very high (VH), for every 30’’ resolution pixel (1 km x 1 km at the Equator). A detailed explanation of this map can be found at: Herrera et al. (2021).Global Subsidence Susceptibility layer: the global subsidence susceptibility map indicates the probability of land subsidence without considering groundwater depletion classified in six intervals from very low (VL) to very high (VH), for every 30’’ resolution pixel (1 km x 1 km at the Equator). A detailed explanation of this map can be found at: Herrera et al. (2021).

Title: Global Subsidence Map

Comments: Subsidence database layer: subsidence occurrences compiled from previous global reviews, nationwide studies and published case studies before 2018. Countries without GW data layer: countries where groundwater data is unavailable, and the potential subsidence only includes information on the global subsidence susceptibility. Global Subsidence Hazard layer: indicates the probability of land subsidence due to groundwater depletion classified in six intervals for every 30’’ resolution pixel (1 km x 1 km at the Equator). Global Subsidence Susceptibility layer: indicates the probability of land subsidence without considering groundwater depletion for every 30’’ resolution pixel (1 km x 1 km at the Equator). A detailed explanation of this map can be found at: Herrera et al. (2021).
Subject: Global subsidence hazard and susceptibility maps due to groundwater depletion classified in six equal intervals of probability. Susceptibility refers to the spatial probability taking into account the influencing environmental variables. Hazard includes susceptibility and the probability of groundwater depletion occurrence.
