With Mexico still reeling from the effects of two devastating earthquakes earlier this month, a new earthquake struck the country on Saturday. The U.S. Geological Survey says this latest quake had a 6.1 magnitude and was centered about 11 miles south-southeast of Matias Romero in the state of Oaxaca. 

Despite occurring about 200 miles from Mexico City, Saturday's quake caused buildings and street signs to sway in the capital, led to the city's seismic alarm being set off, and forced civil defense officials to temporarily suspend their rescue efforts from the earthquake that hit Mexico City earlier this week. Mexico City Mayor Miguel Angel Mancera appeared on Milenio TV to respond to the latest quake, saying there are "no new developments," while acknowledging that Saturday's events brought about "some crises of nerves" among residents. 

This latest earthquake appears to be an aftershock, but it's difficult to determine which one. Over the last month, Mexico has endured three reported quakes. The first was the 8.1 magnitude quake on Sept. 7, which also hit Oaxaca. It was the strongest quake to hit the country in 32 years. That was followed by the 7.1 magnitude quake this past Tuesday. "Since Sept. 7 it has not stopped shaking," Nathaniel Hernandez, a resident of Tonala, Mexico, told the Associated Press.

Meanwhile, Alejandra Castellanos, who was on the second floor of a hotel when the latest quake struck, may have summed up the experiences among the people living in the country after she was forced to evacuate the building with her husband. "I was frightened because I thought, not again," Castellanos said, per the AP.
