Emergency workers in the Philippines recovered 43 bodies from the muddied wreckage of a gold miners’ bunkhouse after Typhoon Mangkhut set off a landslide, burying the remote northern town of Itogon in a river of debris and potentially doubling the country’s death toll, officials said on Monday.

Mangkhut, a super typhoon that slammed into the northern Philippine province of Luzon on Saturday, continued a path of destruction across southern China on Sunday and into Monday.

Officials feared the death toll could surpass 100 in the Philippines, and at least four people were killed in China as of Monday, according to the state news media.

The whir of choppers and the buzz of chain saws were all that was heard on Monday near the mining town of Itogon as workers looking for bodies dug through the mud using shovels and their bare hands — the ground too wet for heavy machinery.

Francis Tolentino, a senior adviser to President Rodrigo Duterte, estimated that nationwide 5.7 million people had been affected by the storm, which hit the country at the height of its powers, with wind speeds topping 150 miles per hour.

Mr. Duterte inspected part of the disaster area on Sunday, and met with top officials in Tuguegarao City for a televised briefing on the damage and the recovery effort.

“I share the grief of those who lost their loved ones,” the president said.

A slightly weakened Mangkhut battered the coast of southern China on Sunday, blowing out the windows of high rises in Hong Kong and causing floods and power outages in Macau.

Nearly 2.5 million people were ordered to evacuate China’s southern province of Guandong, as Mangkhut churned its way toward the mainland. Four people were killed in the province, one of the country’s most populous, according to the state news media.

The storm crossed the southern coast with winds as high as 100 miles an hour. As night fell, the streets of the cities along China’s southern coast largely emptied as residents heeded warnings to stay indoors, having already stocked up on food and water at stores on Saturday and earlier Sunday. Guangzhou ordered all restaurants closed to keep people off the streets, and high-speed rail service was suspended in the province.
