Damage Assessment in the town of La Galarza, Municipality of Izúcar de Matamoros, State of Puebla, Mexico
- United Nations Operational Satellite Applications Programme
- This map illustrates satellite-detected, potentially damaged structures in the town of La Galarza and the surrounding area in the Izucar de Matamoros Municipality, Puebla State, Mexico. The analyzed area is located approximately 15 km North from the epicenter of the 7.1M earthquake that struck the central eastern part of Mexico on 19 September 2017. UNITAR-UNOSAT identified a general moderate level of damaged without seeing evidence of collapsed buildings, nevertheless the analysis showed 358 structures that could be potentially damaged, from which 313 are located in La Galarza. The analysis was performed using a post-event Pleiades satellite image acquired on 22 September 2017 and a pre-event Bing basemap.This is a preliminary analysis and has not yet been validated in the field. It is important to consider the characteristics of the source imagery used in the analyses when interpreting results. For damage assessments it should be noted that only significant damage to the structural integrity of the buildings analyzed can be seen in imagery, while minor damage such as cracks or holes may not be visible at all. For flood extractions using radar data it is important to note that urban areas and highly vegetated areas may mask the flood signature and result in underestimation of flood waters. Users with specific questions or concerns should contact firstname.lastname@example.org to seek clarification.
