Located in the centre of the country, Mexico City lies atop of a high altitude plateau 2,240 metres above sea level. Towering high above the city’s southeast side are two active volcanoes: Popocatepetl and Iztaccihuatl. The surrounding valley, known as the Valley of Anáhuac, is a lake basin with no natural drainage outlet for the waters that flow from the mountainsides, making the city vulnerable to flooding. While not on or near any fault line the City is situated in a very active seismic zone and is extremely vulnerable to earthquakes.

The 1985 earthquake, which measured 8.1 on the Richter scale, caused the deaths of about 10,000 people and caused serious damage to the Mexican capital; thousands of buildings were flattened and a quarter of a million people lost their homes. Health facilities were especially hard hit, with many hospitals and clinics destroyed. Nearly one-fifth of the schools in the city were destroyed or seriously damaged as well as water, electrical and telecommunications systems.
To prepare for future disasters, Mexico City installed a public earthquake early warning system in August 1991 – the Seismic Alert System or Sistema de Alerta Sísmica in Spanish – that provides alerts through media outlets and Internet applications when an earthquake is detected. The system is capable of generating warning signals of about 60 seconds when detecting strong earthquakes occurring 280 km away.
