A strong apparent aftershock from a powerful earthquake late last month shook Mexico Monday, officials said. According to officials, no immediate damage or injuries were reported from the earthquake, which had an initial magnitude of 6.3. The U.S. Geological Survey reported a preliminary magnitude of 6.3 for Monday's aftershock. It said the epicenter was near the border of Guerrero and Oaxaca states in southern Mexico, which was close to the epicenter of a strong earthquake on March 20. Since that quake, Mexico has experienced a number of aftershocks.
