Description:
This map illustrates satellite-detected, potential areas of debris clearance in the town of Jojutla, Jojutla Municipality, Morelos State, Mexico. The analyzed area is located approximately 82 km west of the main shock epicenter of the 19 September 2017 M7.1 earthquake. UNITAR-UNOSAT identified ~9,400 m2 of areas where debris have been removed, located in the most affected part of the town after the earthquake. In addition, ~ 6,500 m2 of standing debris were identified and ~ 5,000 m2 of potential debris disposal were visible. The analysis was performed using a post-event Pleiades satellite image acquired on 05 October 2017 and WorldView-3 satellite image acquired on 06 October 2017.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 unosat@unitar.org to seek clarification.
