A powerful earthquake jolted central Mexico on Tuesday, causing buildings to sway sickeningly in the capital on the anniversary of a 1985 quake that did major damage.

National Civil Protection chief Luis Felipe Puente tweeted that there were no reports of damage so far, but thousands of people fled office buildings along the central Reforma Avenue as alarms blared, and traffic stopped around the Angel of Independence monument.

The US Geological Survey said the quake had a magnitude of 7.1 and was centered near the Puebla state town of Raboso, about 76 miles (123 kilometers) southeast of Mexico City.

Puebla Gov. Tony Galil tweeted that there had been damaged buildings in the city of Cholula including collapsed church steeples.

In Mexico City, thousands of people fled office buildings and hugged to calm each other along the central Reforma Avenue as alarms blared, and traffic stopped around the Angel of Independence monument.

In the Roma neighborhood, which was struck hard by the 1985 quake, piles of stucco and brick fallen from building facades littered the streets. Two men calmed a woman seated on a stool in the street, blood trickling form a small wound on her knee.

At a nearby market, a worker in a hardhat walked around the outside warning people not to smoke as a smell of gas filled the air.

Market stall vendor Edith Lopez, 25, said she was in a taxi a few blocks away when the quake struck. She said she saw glass bursting out of the windows of some buildings. She was anxiously trying to locate her children, whom she had left in the care of her disabled mother.
