MEXICO CITY — The U.S. Geological Survey says the new earthquake to strike Mexico had a magnitude of 6.2 and was centered in the southern state of Oaxaca. That’s the region most shaken by a magnitude 8.1 quake that hit on Sept. It also swayed buildings in Mexico City, which is trying to recover from a magnitude 7.1 temblor that struck on Thursday, killing at least 295 people. It’s not immediately clear if the new quake caused damage or injury. The quake was much weaker than the one that hit on Tuesday, killing at least 295 people and knocking down buildings across the capital. A magnitude 8.1 earthquake struck earlier this month near the state of Chiapas. This story will be updated.
