Earthquake Shakes Southern Philippines

A 5.3-magnitude earthquake shook off the southern Philippines on Friday, making objects to shake but causing no damage, the government's seismology office said.

There was no immediate tsunami warning but scientists cautioned there may be aftershocks.

The quake struck at 8:07 am (2307 GMT Thursday) and was centered 32 kilometres (20 miles) south of the southern city of Davao on Mindanano island at a depth of 29 kilometres.

The Philippines sits on the Pacific Ring of Fire, where continental plates meet, causing frequent seismic and volcanic activity.
