The earthquake of Mexico City of 1985 is considered to have had a magnitude of VI to VIII (moderate to severe) in the Mercalli Scale, depending on the affected area.

The 1985 Mexico City earthquake, a magnitude 8.1 earthquake that struck Mexico on 19 September 1985 in the morning at 7:19 local time.
In seismology (the study of seismic waves or vibrations in the ground / earthquakes) the Richter scale is a magnitude scale. Magnitude scales show the amount of energy released by an earthquake. In the case of the Richter magnitude this is based on the amplitude of the seismic waves measured on a seismometer and the distance of the seismometer station from the epicentre of the earthquake. The magnitude value should be the same for a given earthquake no matter where it is recorded. The Mercalli scale is an intensity scale. This gives information on the perceived ground shaking in a specific location. The value is derived from witness reports on the perceived violence of the shaking, from the damage done to buildings and other infrastructure and also based on measurements from accelerometers and other seismic recording instruments in order to make the Mercalli intensity value a less subjective parameter. The intensity and damage to infrastructure can be influenced strongly by a number of variables including local ground conditions and the use (or otherwise) of earthquake resistant design. Please see the related questions for more information.
Yes. The most destructive in modern times occurred on September 19, 1985 and resulted in 45,000 dead and a huge economic loss. Its intensity was 8.0 Mw (8.1 on Richter Scale). The latest, high-intensity earthquakes in Mexico City happened on March 20, 2012 and April 18, 2014. Their intensities were 7.8 Mw and 7.5 Mw, respectively. None of these resulted in fatalities.

It was (and still is) an important industrial and services hub, with cement, steel, oil refining and manufacturing. This is why the 1985 Mexico City earthquake was so devastating: at the time, Mexico City represented 25% of all Mexico's GDP.
