This story, originally published by WIRED, discusses the sinking phenomenon in Mexico City due to subsidence, with buildings and infrastructure sinking up to 20 inches annually. Satellite data has allowed scientists to measure the sinking rates, especially in critical areas like the city’s metro system. With groundwater overextraction worsening the situation, some metro segments are moving faster than designed, necessitating immediate attention before typical maintenance thresholds. The study calls for intervention to prevent potential disasters and highlights the importance of sustainable water management to combat subsidence in cities worldwide.
