The local authorities in Iztapalapa, in the eastern section of the Mexico City Metropolitan Area, and one of the most interesting locations in Mexico in which to witness Easter celebrations, calculate that around 10,000 homes are in the area are at “high risk” of serious damage due to ground subsidence. Some parts of the city are falling in elevation as the ground contracts by up to 40 cm/yr.
Low-lying Iztapalapa is one of the most densely populated parts of the city, and is also prone to frequent flooding. Experts say that the severe damage evident in many buildings in the area has been occasioned by ground subsidence, due to the excessive volumes of water being pumped out of the subsoil to satisfy the insatiable demand of Mexico City.
In a short 3-minute news video in Spanish that is linked to in this recent article, Lourdes, a local resident offers us a tour of her home, showing us the damages caused by subsidence. She describes how “the crack that started from outside the house has widened every day and is now almost the width of a hand.” The video shows how the walls of her home are separating; the house is clearly in danger of collapse. Lourdes lives in this house with her four children; some rooms are already far too damaged to be safely used by the family.
