Disaster officials also added that 31 people were injured, 11 severely, as the mudslide engulfed houses and two buses in Masara village.
The disaster struck the gold mining village in Davao de Oro province following heavy rains that have swamped the region in recent weeks.
"There was no sign that a landslide would occur because the rains stopped on Thursday and by Friday it was already sunny and hot," provincial disaster official Edward Macapili said.
Military joins rescue operations
The military, which has been deployed to help in the rescue efforts, said three seriously injured people were airlifted for medical help.
On Wednesday, the military said in a post on Facebook that "impassable" roads and "no cellphone signal in the area" posed significant challenges to their work.
Meanwhile, 285 families from Masara and four nearby villages have been evacuated to safer areas, Macapili said.
At least 18 people died from landslides and flooding in the region last week, the national disaster agency said.
