Officials say a strong earthquake has shaken a remote area of eastern Indonesia. The quake was located fairly deep below the northern Molucca Sea and no tsunami warning was issued.

The U.S. Geological Survey says the earthquake measured magnitude 6.4 and struck late Sunday. It says it was centered 138 kilometers (85 miles) west-northwest of the town of Tobelo at a depth of 70 kilometers (43 miles). The area is also south of the southern Philippines.

There were no immediate reports of damage or injuries from the remote area.

Indonesia straddles a series of fault lines that make it prone to volcanic and seismic activity.

A giant quake on Dec. 26, 2004, triggered a tsunami in the Indian Ocean that killed 230,000 people, half of them in Indonesia's Aceh province.
