The United States Geological Service said the quake registered a 7.1 magnitude strength with an epicenter about 50 miles southwest of downtown Mexico City.

The earthquake comes after a citywide earthquake drill commemorating the anniversary of a 1985 quake that killed thousands of people.

An 8.1 magnitude quake struck southern Mexico last week, causing damage and killing nearly 100 people in the southern states of Oaxaca and Chiapas.
