Mexico City has recently received considerable attention due to its worrying behaviour that cannot be explained by usual urban factors. According to recent observations carried out using satellites, some areas of Mexico City have started sinking at an alarming rate. Although there is no catastrophic subsidence process taking place in Mexico City, the phenomenon is becoming more acute and noticeable in some specific regions. There is no doubt that the process is associated with the existing water problem, which is affecting millions of people in Mexico City.
The subsidence process in Mexico City does not lead to catastrophic consequences at once. Nevertheless, the city has started changing gradually and irreversibly. Satellite images provide a better understanding of how the city's surface moves. However, they also indicate how complex the interaction between water and geological processes has become in Mexico City.
