If a magnitude 4 microquake was registered in Mexico City, it could cause a delicate situation, warns Dr. Delfino Hernández Láscares, an academic at the Universidad Autónoma Metropolitana (UAM).

According to the specialist, the micro-seisms that are being recorded in the subsoil of the Mexican capital are the product of active geological faults that are found at depths of between 1.5 and 3 kilometers and manifest themselves on the surface in less than a second.

During the week of May 10 to 16, a total of 25 telluric movements have been felt, 90 percent of them in the region of the Mayor’s Office of Magdalena Contreras, reported Dr. Hernández Láscares. These seismic events occur when a fracture is generated in the Earth’s crust, which causes a sudden and violent release of energy in the form of seismic waves.

The National Seismological Service reports that these waves propagate in all directions at different speeds, some of them reaching between 8, 9 and 10 kilometers per second. This means that when there is a microseism below a demarcation, it is reflected almost instantly on the surface and, depending on its magnitude, it can be felt in neighboring municipalities.
