"I'm scared," said Sarai Luna Pajas, a 22-year-old social services worker standing outside her Mexico City office building moments after it hit. "We Mexicans are not used to living with so much fear, but all that is happening - the economic crisis, the illnesses and now this - it feels like the Apocalypse."
Co-worker Harold Gutierrez, 21, said the country was taking comfort from its religious faith, but he too was gripped by the sensation that the world might be coming to an end.
There were no reports of injuries or major damages in Mexico City.
The quake had a magnitude of 5.6 and was centered near Chilpancingo, about 130 miles southwest of Mexico City or 50 miles from Acapulco, according to the US Geological Survey.
Tourists also streamed out of hotels in Acapulco and congregated on sidewalks and medians for several minutes. Local Civil Protection officer Silvia Rodriguez said there were no injuries there.
USGS earthquake analyst Don Blakeman said the quake was felt strongly in Mexico City because the epicenter was relatively shallow and the ground under the capital tends to intensify shock waves. T
