At least 50 homes suffered damage in the southern state of Oaxaca, which, along with Mexico City, is still reeling from earthquakes that caused widespread damage in September. The ministry issued a statement on Twitter saying two people on the ground were killed when the helicopter came down. In Mexico City, the seismic alarm sounded 72 seconds before tremors were felt, Mayor Miguel Angel Mancera said, giving residents time to flee to the streets. People stand on the street after an earthquake shook buildings in Mexico City on Friday. But the quake was a far cry from the tremors that struck Mexico in September, Martinez said.
