A 6.9-magnitude earthquake struck off the Philippine island of Mindanao on Saturday triggering a brief tsunami warning. The quake struck southeast of Davao City at a depth of 59 kilometres, the US Geological Survey said, a week after a volcano-triggered tsunami killed more than 400 people in neighbouring Indonesia. The Pacific Tsunami Warning Center warned “hazardous tsunami waves from this earthquake are possible” along the coasts of Indonesia and the Philippines.
However, waves were forecast to be less than 30 cm above tide level, it said, while Philippine monitors warned that “minor sea level disturbances” were to be expected.
The Philippine government’s seismology institute initially advised people to “stay away from the beach and not to go to the coast fronting the Philippine Sea,” for about two hours after the quake.
