Resumen:

Land subsidence affects urban areas with rapid development during the last thirty years in central Mexico. The use of land represents a great challenge for urban planning, and the issue is increased when sustainable water resources management need to be added. Mexico inhabitants rely on groundwater for about 60% of water supply. Furthermore, the most of the cities are located in volcanic valleys filled with fine and coarse grained sediments interbedded with pyroclastic and volcanic materials. Three study cases are presented in this work for comparative purposes: Mexico, Queretaro and Irapuato cities. Compaction associated to groundwater depletion have caused differential subsidence, ground fracturing and reactivation of faults, depending on the local geological setting. Remote sensing monitoring methods of land subsidence have proved to be useful tools to assess this geological risk for urban planning, nevertheless more efforts need to be addressed for the implementation of in-situ monitoring and other techniques to prevent and manage damage to urban infrastructure.
