The storm made landfall on Sunday morning with winds of up to 90 kilometers per hour (56 mph), according to media reports, uprooting trees and blowing the roofs off houses and schools.
Vamco is the latest in a series of storms that have pummelled Vietman over the past six weeks causing flooding and landslides that have killed at least 159 people and left 70 others missing.
Initial reports from the Disaster Management Authority on Sunday said that five people were injured while they were trying to secure their houses.
Vamco has weakened since hitting the Philippines as a typhoon with winds of up to 155 kph, but state media said it had still caused significant damage, though details were not immediately available.
Authorities evacuated nearly 650,000 people from seven coastal provinces to higher and safer ground before the storm hit to try to reduce casualties.
Agriculture and Rural Development Minister Nguyen Xuan Cuong told the VNExpress news website he hoped the precautions would minimise the storm’s impact.
Vamco caused severe damage in the Philippines, causing flooding that affected more than 340,000 people.
Philippine authorities said Sunday the death toll had risen to 67, though floodwaters are now receding, giving hope that the worst could be over.
Roads and bridges have been washed away, power supplies disrupted, and crucial food crops destroyed, leaving at least 150,000 people at immediate risk of food shortages.
