Mexico City (NBC News Channel) -- On September 19th 1985, a powerful earthquake struck Mexico City, leaving 10,000 people dead and 30,000 injured and thousands more homeless.
At 7:18a.m. that day, an 8.1 magnitude earthquake hit Mexico City. That's one of the strongest to ever hit the area.
The quake was centered 250 miles west of the city but, due to the relatively unstable ground underneath the city, serious shaking lasted for nearly three minutes.
The prolonged ground movement caused several old hotels to crumble.
A building fell, trapping hundreds of students who were attending early-morning classes.
Many factories in the city, built with shoddy materials, also could not stand. Further, the tremors caused gas mains to break, causing fires and explosions throughout the city.
When the damage was finally assessed, 3,000 buildings in Mexico City were demolished and another 100,000 suffered serious damage.
