Damage assessment associated with land subsidence in the San Luis Potosi-Soledad de Graciano Sanchez metropolitan area, Mexico, elements for risk management
In the present study, damages associated with land subsidence phenomena in residential structures within the San Luis Potosi-Soledad de Graciano Sánchez Metropolitan Area (San Luis Potosí state, Mexico) were estimated based on a methodology that has been adapted to the Mexican context. As Blong’s (Nat Hazards 30:1–23, <CitationRef CitationID="CR3">2003</CitationRef>) methodology does not include the Central Damage Values to land subsidence, these were calculated based on observations made in 282 damaged houses. According to the Central Damage Values, 27 % of the affected property is low damage, 33 % moderate, 21 % high, 15 % severe and 4 % have been demolished. The affected properties correspond to 39,537 m<Superscript>2</Superscript> of construction and 40,782 m<Superscript>2</Superscript> of surface. The Replacement Ratio is estimated at 1,307 average homes. The damage in equivalent homes is 282, and monetary cost is $2,516,944 USD ($30,203,329 MXN). The collected data, comprised into a GIS, offer the possibility to spatial and temporal monitoring of the damage provoked by land subsidence in homes.
