CNN PRODUCER NOTE spnichol is a newspaper reporter in Mexico City, Mexico, and was in his office building 'when the doors started to swing back and forth slightly. I didn't feel anything immediately, but my co-workers, who are more used to frequent earthquakes, recognized that it was an earthquake and the entire building evacuated using the stairs. Outside, in the business district of Lomas de Chapultepec, there were hundreds, if not thousands of people, crowding the streets and sidewalks waiting for instructions on what to do.' He said most people waited between 10 and 20 minutes before going back inside. 'About 40 minutes after the initial quake, we started to feel very minor aftershocks and we observed the curtains moving back and forth.'
