The village of Ucab in the picturesque Cordillera region was hit by one of 50 landslides triggered by heavy rains brought by Typhoon Mangkhut.
Taufan tropika tersebut tiba ke daratan tenggara negara itu di wilayah Guangdong semalam selepas membadai Filipina mengakibatkan angka korban dijangka melebihi 50 orang.
Mangkhut had shut the city all day Sunday after the Observatory gave the storm its highest warning signal.
More than 2.4 million people have been relocated and nearly 50,000 fishing boats were called back to port.
Mangkhut’s structure will be ripped by wind shear, weakening its top winds as it approaches the coast to Hong Kong’s west.
Mangkhut was still punching powerful winds and gusts equivalent to a Category 4 Atlantic hurricane when it hit the Philippines.
In the Philippines, economic losses could reach 6.6% of gross domestic product, or more than US$20 billion.
Mangkhut entered the Philippines as a super typhoon in the early hours, and sent winds and rains across Luzon, home to about half the country's 105 million people.
Taufan Mangkhut dijangka melanda kawasan darat antara Guangdong barat dan timur Hainan malam ini membawa angin kencang dan hujan lebat.
Super Typhoon Mangkhut, a category 5 storm, entered Cagayan province on the main island of Luzon in the early hours.
Taiwan's central weather bureau predicted that Mangkhut would be nearest to the island on Saturday, bringing heavy rains to its southern and eastern parts although it was unlikely to make a direct hit.
Thousands fled their homes on the Philippines' northern coastal tip ahead of the early Saturday landfall of what has been called the strongest typhoon yet this year.
The state weather service says Mangkhut will be the strongest typhoon so far this year, with sustained winds of 205kmh.
The civil defence office in Manila said towns and cities on Mangkhut's path are preparing government buildings as evacuation centres, stockpiling food and other emergency rations.
