A 7.3-magnitude earthquake occurred in the Philippines’ Moro Gulf at 6:08 a.m. Saturday, July 24, 2010.
The epicenter of the earthquake was 573 miles southeast of Manila. No damage or deaths have been reported and no tsunami warning has been issued.
Because the earthquake struck so deep, at a depth of 375 miles (603 km), severe damage is not anticipated.
This area suffered a 6.0-magnitude earthquake just two months ago. The earthquake in May was also in the Moro Gulf, roughly 25 miles from Cotabato, Mindanao, Philippines and 570 miles south-south east from Manila.
The initial quake that preceded the aftershock had a magnitude of 6.9, the U.S. Geological Survey said.
An earthquake in 1976 in the Moro Gulf killed more than 5,000 people. The 1976 Moro Gulf earthquake was 8.0 magnitude and was followed by a tsunami.
