A moderate earthquake struck central Mexico Friday, forcing residents and office workers to evacuate buildings in Mexico City.
Officials say no major injuries or damages were immediately reported.
The U.S. Geological Survey estimates the earthquake's magnitude at 6.0. An aftershock that measured 5.5 hit a few hours later.
The center says the earthquake, which hit Friday morning local time, was centered in the southwestern state of Michoacan, about 200 kilometers southwest of Mexico City.
In 1985, a 7.8 magnitude earthquake in Mexico City killed more than 10,000 people.
