A 7.1 magnitude quake hit Mexico on Tuesday, killing at least five people, collapsing buildings and trapping an unknown number of people.
The event caused serious damage to the Greater Mexico City area and the deaths of at least 5,000 people.
The Mexican Seismological Service said the natural disaster was centred on Axochiapan in the central state of Morelos, some 160km from the capital.
With more than 8 million people, Mexico City is one of the largest cities in the world.
Los Angeles was rocked by a 3.6 magnitude natural disaster just before midnight Monday night, with its epicenter about 13 miles from the shaky city center.
