Mexico City, Mexico has a very prominent historical record of earthquakes. One example is the 1985 earthquake which was one of the most devastating earthquakes in the history of America. On September 19 th , 1985, Mexico City was struck with an 8.1 magnitude earthquake (Richter scale). The epicenter of the earthquake was off the Pacific cost of the Mexico State of Michoacan in the Coco Plate subduction zone. Due to the relatively unstable ground, the intensity of the shaking increased and the earthquake lasted up to three minutes. In those three short minutes, 10,000 people died, 30,000 people were injured, 100,000 were left homeless, 3,000 buildings were demolished and 100,000 buildings suffered serious damage.
