A 7.1-magnitude earthquake has hit Mexico leaving buildings shaking in the capital of Mexico City and sending people fleeing into the street.
The tremor hit just hours after emergency drills around the nation on the anniversary of a devastating quake that killed thousands in Mexico City in 1985.
Today's quake hit 5 miles southeast of Atencingo in the central state of Puebla at a depth of 32 miles, the US Geological Survey said.
Luis Felipe Puente, the head of Mexico's civil protection agency, said on his Twitter account that there were no immediate reports of damages.
A powerful 8.1 quake hit Mexico earlier this month killing at least 98 people.

On Mexico City's main boulevard, thousands of people streamed out of buildings into the streets in a panic, filling the plaza around the Independence Monument with a mass of people.
Traffic came to a standstill as masses of workers blocked streets while clouds of dust rose from fallen facades.
Office workers were also seen hugging each other to calm themselves.
In the city's Roma neighborhood small piles of stucco and brick fallen from building facades littered the streets.
Two men calmed a woman, blood trickling form a small wound on her knee, seated on a stool in the street, telling her to breathe deeply.
At a nearby market, a worker in a hard hat walked around the outside of the building, warning people not to smoke as a smell of cooking gas filled the air.
Market stall vendor Edith Lopez, 25, had been in a taxi a few blocks away when the quake struck. She said she saw glass bursting out of the windows of some buildings.
