New Earthquake Strikes Southern Mexico

The U.S. Geological Survey says a new earthquake which stuck Mexico Saturday had a magnitude of 6.1 and was centered in the southern state of Oaxaca. 

It initially calculated as a magnitude 6.2 quake.

The director of Mexico's disaster agency says it's an aftershock of the 8.1 quake that hit on September 7 off the country's southern coast.
