A 5.7 magnitude earthquake rattled southern and central Mexico on Thursday, but there are no immediate reports of damage or injuries.
Workers at some Mexico City office towers temporarily evacuated their buildings but quickly re-entered after the swaying stopped.
The U.S. Geological Survey said the quake occurred around 8:30 a.m. local time (13:30 GMT) and was centered near the city of Huajuapan de Leon in southern Oaxaca state, about 140 miles (230 kilometers) southeast of the capital.
One minute before the earthquake, a small explosion was recorded at Mexico's most active volcano, Popocatepetl . . .
