A strong earthquake shook southern Mexico early Wednesday morning, reportedly killing one person in Oaxaca and being felt as far away as Mexico City and the states of Veracruz, Puebla, and Guerrero. The quake struck at 2:22 a.m. with an epicenter in rural southwestern Oaxaca near the Pacific Ocean. It lasted half a minute and was strong enough to shake buildings in Mexico City, sending frightened people onto the street despite the hour.
