CNN: "Two new earthquakes shake southern Mexico ..."

I think that technically at least one of those two quakes, the first one, should be called an aftershock. I don't know about the second. See the Los Angeles Times report Sept 23 - 7:30 PM filed from Mexico City re the first quake yesterday.

From the CNN report updated 12:57 AM ET, Sun September 24, 2017:

Two more earthquakes shook southern Mexico on Saturday, further rattling a country still coming to grips with the devastation from stronger temblors earlier this month.
A 6.1 magnitude earthquake Saturday morning was centered in Oaxaca state near Matias Romero, a town about 275 miles southeast of Mexico City, the US Geological Survey said. Roughly speaking, the epicenter was between the centers of this month's two more violent earthquakes -- the 7.1 magnitude temblor that hit Tuesday closer to the capital, and the 8.1 magnitude quake that struck September 8 off the southern Pacific coast, near Chiapas state. 

[Pundita note: I thought it struck on Sept 7; yes, from Wikipedia, Sept. 7, not 8.]
A 4.5 magnitude quake hit Oaxaca at 7:06 p.m. ET. That temblor occurred at a depth of 8.9 kilometers, according to initial readings by USGS.

In Oaxaca, some highways and a bridge that had been damaged during the September 8 earthquake collapsed, Mexico's federal police said.

Mexico City did not appear to have sustained significant damage in the earlier and stronger of Saturday's two quakes, said the country's office of the secretary of public security.

Warning sirens sounded in Mexico City after the morning quake was detected, interrupting rescue operations at some of the dozens of buildings that collapsed from Tuesday's earthquake.

CNN video showed rescuers walking off one vast pile of rubble to more stable ground in case any shaking shifted debris further.
