The 7.4-magnitude quake that shook Mexico City for more than a minute sent office workers fleeing into the streets. Cell phone lines went down, building were evacuated, traffic snarled and the stock exchange had to suspend trading early.
The good news is no deaths were reported and the quake caused no major disruptions to air travel or to oil installations, but it scared many residents.
