The U.S. Geological Survey says a 5.8 earthquake struck the southern Philippines Saturday just before the midday hour. The earthquake hit at around 11 pm Friday night eastern time in the U.S.
The earthquake was about 6 miles below the surface, and its epicenter was located about 330 miles east-southeast of Manila.
The 5.8 quake follows a 5.7 earthquake that hit the north end of the Philippines on Friday evening. It was centered about 385 miles north of Manila and was also centered just over 6 miles below the surface of the earth.
The Philippines are a volcanic island chain, and the area is very active geologically. The island chain is a part of an ocean ridge that is bordered to the east by a deep ocean trench that is part of a geologic subduction zone.
So far, no damage or injuries have been reported from either earthquake.
