MANILA, Philippines - There are no reports of damage or injuries today after a strong earthquake that rattled a southern Philippine island.
The Mindanao quake was measured at magnitude 6.5 by Philippine authorities while the U.S. Geological Survey said it was a 6.4. No tsunami warning was issued.
A civil defense official says the quake was strong but deep underground.
Several aftershocks were recorded.
The Philippine archipelago is located in the Pacific "Ring of Fire," where earthquakes and volcanic activity are common. A magnitude-7.7 quake killed nearly 2,000 people on the northern island of Luzon in 1990.
