Reuters has a short bit up:
“Oaxaca’s civil protection service said no damage had been reported so far.
“In Mexico City, tall buildings swayed for more than a minute as seismic alarms sounded throughout the city, and tremors were felt as far away as Guatemala to the south.
“Television images showed thousands of people in the streets in the city center, where crowds had gathered to celebrate the Chinese New Year.”

I have a friend in Oaxaca and he said some decorative things have fallen in some of the older historic buildings but so far no reports of major damage. Hope the aftershocks aren’t bad!
