Summary: | In the Mexican district of Santa Ana Tlapaltitlán, the Process of Subsidence-Geological fault has generated damages to the urban infrastructure, which translates into socioeconomic losses that for years have not been calculated. The lack of this type of studies occurs because most of the investigations tend to focus on analyzing the degree of subsidence and detection of the threatened areas. The present study aims to assess the socioeconomic damage by differential subsidence in this district through a quantitative methodology based on the calculation of demerit factor and equations that assess the valuation of the economic impact for the land, buildings, and the exposed population.The results obtained show that the economic damage referring to lands was of $16 869 901 Mexican pesos. and, $ 6,402,726 for the economic damage associated to buildings. Together, results sum up a global loss of $23,272,627 (US$ 1,208,971). In relation to the exposed population, 14 518 individuals,163 of them inhabit the most affected buildings. Differential subsidence generates significant socioeconomic damages in different geographical areas, hence, it is concerning that to date there are no concrete economic resources allocated to reduce this type of hazard exposure and disaster risk.
