It's not clear how many people may have been trapped in their homes when part of a mountainside cascaded down Masara village on Tuesday night in the far-flung town of Maco in Davao de Oro province.
Provincial government spokesman Edward Macapili said eight miners, who were among those waiting on two parked buses to take them home, jumped out of the windows or ran away and survived.
Torrential rains that have swamped the region on and off in recent weeks have eased and the weather was clear in the previous three days, Macapili said.
"It happened so fast," he told The Associated Press. "They suddenly saw the landslide cascading directly toward them."
The military earlier reported a higher number of missing and surviving miners, saying impassable roads and poor communication lines were hampering efforts to get more specific details from the village.
Three seriously injured victims would be evacuated by helicopter, regional military spokesperson Rosa Rosete-Manuel said.
Army troops, police and villagers resumed a search for the missing Wednesday after suspending it late Tuesday due to the darkness and fears of more landslides.
About 600 villagers living near the landslide-hit area have been evacuated to safer communities.
"There are reports of unaccounted individuals believed to be affected by the landslide," Rosete-Manuel said without elaborating.
Earthquakes in recent months had damaged buildings in the southeastern region, and more than a dozen villagers have died in recent weeks from flooding and landslides, according to disaster-response officials.
A landslide buried a house and killed 10 people last month in Monkayo town, also in Davao de Oro province, officials said.
