Manila: An earthquake of 6.9 magnitude struck off the southern Philippine island of Mindanao on Saturday and hazardous tsunami waves were possible on parts of the coasts of the Philippines and Indonesia, the Pacific Tsunami Warning Centre said.

There were no immediate reports of casualties or damage, from the earthquake, which the US  Geological Survey (USGS) said struck 193 km east of the Philippine city of General Santos, at a depth of 60 km.

"Hazardous tsunami waves from this earthquake are possible within 300 km of the epicentre along the coasts of Indonesia and the Philippines," the Pacific Tsunami Warning Centre said.

Meanwhile in Indonesia, bad weather and a massive ash column hampered efforts to assess whether Indonesia's Anak Krakatau volcano island could trigger another deadly tsunami as authorities said on Friday the search for victims will continue into January. The death toll for the Sunda Strait tsunami a week ago is so far 426, with more than 40,000 people displaced.
