On September 19, 1985 the most devastating earthquake in the recorded history of Mexico hit Mexico City at 7:12 am. The earthquake was of magnitude 8.1 and the city was not prepared for a disaster of this force. The casualties of this earthquake are still disputed. This example of buried and inadequate evidence demonstrates more than geological problems within the country; 10,000 is the most commonly cited number of deaths. The terrain, unstable since the city was built on Lake Texcoco, increased the vibration of buildings above ten stories, making them much more vulnerable to collapse. My parents lived in Mexico City at the time of this disaster and witnessed the chaos. The aftermath could have been lessened if contractors obliged by regulations instead of using cheap material to pocket leftover money. This disaster resulted in high death tolls and added another highlight of government corruption in Mexico.
