Resumen:

Mexico City is one of the largest cities in the world that is subjected to a number of natural and manmade hazards. Indeed, a 5500m-high active volcano -Popocatepetl- is 60km away from the city outskirts. From the point of view of the seismic hazard, local faults are capable of producing moderate intensities at high frequencies, whereas largest intensities at low frequencies are due to earthquakes that occur along the subduction zone in the Pacific coast. Such subduction area is as close as 300+ km from the city. Large intensities within the city are mainly due to the dynamic characteristics of the soft soil deposits in the former lake bed area. In regards to hydrometeorological hazards, the subsidence of the city, due to soft clay consolidation, has forced pumping of the water to the drainage system. Moreover, this system is insufficient and there are symptoms of clogging along some sections. Therefore, in case of a power shortage, the city may flood. Pollution in the city, caused by car and industry emissions, in the air, soil and water, are critical issues. Copyright © (2006) by Earthquake Engineering Research Institute.
