The landslide hit the mountain village of Masara in Davao de Oro province on 6 February after weeks of torrential rains. It struck outside a gold mine in Maco town in Davao de Oro province, and buried homes and vehicles that were supposed to ferry employees of the mining company.
The authorities plan to shift the focus from search and rescue to search and retrieval beginning on Tuesday, Maco town disaster officer Ariel Capoy said.
“It is almost a week after the incident and... we are assuming that no one is alive there," Edward Macapili, a disaster agency official, told AFP news agency. "There is already a foul smell in the area now so there’s a need to fast-track the retrieval."
Even though over 300 people were involved in rescue operations, the process was being hampered by thick mud, heavy rain, damaged communication lines, and the threat of further landslides, officials said.
Rains have led to tens of thousands of residents moving to emergency shelters.
Heavy rainfall, mountainous terrain, and deforestation from mining have made the islands prone to landslides.
More than 1,100 families have been moved to evacuation centers for their safety, disaster response officials said earlier.
The area has been swamped by heavy rains in the weeks before the landslide struck. Earthquakes also damaged houses and buildings in the region in recent months, officials said.
The US, through the US Agency for International Development, was providing US$1.25m humanitarian aid to the affected communities in the southern islands, its embassy in Manila said in a statement.
The US Defense Department also provided two C-130 cargo planes to help deliver food packs to the affected communities.
