GUINOBATAN, Philippines — Officials could only apologize Monday when asked about the prospects of finding survivors in the towns and villages swamped by mudslides from devastating Typhoon Durian, which has killed an estimated 1,000 people in the Philippines.

"At this time, no more. I'm sorry," said Juan Garcia, mayor of the town of Guinobatan. "It's almost impossible. They have been buried under sand and boulders. I don't think they can survive."

Officials in Vietnam said today that at least 10 people were dead after Durian, downgraded to a tropical storm, hit the country's southern coast. Fifty others were injured when their houses collapsed.

On Thursday, Durian lashed the Philippines with 165 mph winds and a five-hour deluge that dislodged tons of debris from the slopes of the Mayon volcano. Walls of mud and boulders destroyed nearly every standing structure in their path.

Official figures showed 450 dead, 507 injured and 599 missing, but Sen. Richard Gordon, head of the local Red Cross, said he believed more than 1,000 died in the thousands of homes buried under volcanic debris, mud and floodwaters.
