"They are still under the rubble, they are still there. They are covered in shallow earth, we need a backhoe," Parba said.
A man embracing a child in a house was dug out by rescuers using a backhoe in a poignant scene witnessed by journalists.
Authorities have limited the number of rescuers and other people inside the stricken villages, fearing heavy rains on the loose and soaked ground could cause new slides.
Thursday's landslide also covered part of a river, prompting officials to order a temporary canal to be dug.
About 270 government troops and policemen were deployed to prevent residents from returning to high-risk villages, Sinas said.
President Rodrigo Duterte was to visit Naga city in Cebu province yesterday as he faces his latest crisis.
The landslide in the central region occurred as parts of the far northern Philippines deal with damage from a typhoon that hit last weekend. At least 95 people were killed and more than 50 are missing, many in the gold-mining town of Itogon in the north where landslides hit houses and a chapel where people had gathered in the storm.
Cebu province was not directly hit by Typhoon Mangkhut but the storm intensified the seasonal monsoon rains that normally fall in tropical Asia.
It's not clear what set off the landslide, but some residents blamed limestone quarries, which they suspect may have caused cracks in the mountainside facing their villages.
The Philippines is one of the world's most disaster-prone countries.
