Mexico’s Oaxaca region was shaken by a 6.1-magnitude earthquake Saturday that downed a highway bridge, damaged homes and buildings and rattled people as far away as Mexico City.

The quake was an aftershock from the 8.2-magnitude quake in Oaxaca on Sept. 7, which killed nearly 100 people and left scores in the region homeless.

Experts have recorded thousands of aftershocks from that quake. The aftershock Saturday was one of the most powerful.

One woman in Oaxaca state died when a wall of her home fell in the town of Asuncion Ixtaltepec. Seven other people suffered non-life-threatening injuries in Oaxaca state.

The new quake was “horrible,” said Bettina Cruz, who lives in Juchitan, Oaxaca. “Homes that were still standing just fell down,” Cruz said, her voice shaking. “It’s hard. We are all in the streets.”

Nataniel Hernandez said by phone from the southern state of Chiapas, which was also hit hard by the earlier quake, that “since Sept. 7 it has not stopped shaking.”

In Mexico City — 290 miles from Oaxaca — the quake was strong enough to frighten people still shaken by a 7.1-magnitude quake on Tuesday that killed more than 300.

“I was frightened, because I thought, not again!” said Alejandra Castellanos, who had been on the second floor of a hotel in central Mexico City.

Residents in Mexico City slept in tents and accepted food and coffee from strangers, as some waited for information about their missing family members.

Patricia Fernandez Romero’s 27-year-old son went missing after Tuesday’s quake.

“There are moments when you feel like you’re breaking down,” she said. “And there are moments when you’re a little calmer . . . They are all moments that you wouldn’t wish on anyone.”
