The Philippine Seismological Agency (Phivolcs) warned that people living near the coast in the provinces of Surigao del Sur and Davao Oriental should “evacuate immediately” or “move further inland.” Both provinces are largely rural and not densely populated, unlike other parts of the Philippines.
It was also noted that ships already at sea during this period should remain in deep water until further instructions were given.
The United States tsunami warning system warned that there could be waves up to 3 meters above the normal tide on some Philippine coasts, although it later stated that there was no risk of a tsunami.
