Searchers have found another body in the debris from a massive landslide in northwestern Washington state, bringing the death toll to at least four from the wall of mud and debris that swept through a small riverside neighbourhood.
At least 18 people remained missing, though authorities warned that number could grow. Late Saturday, rescuers heard cries for help, and a day later, they heard nothing.
Crews were able to get out to the muddy, tree-strewn area after geologists few over in a helicopter and determined it was safe enough for emergency responders and technical rescue personnel to search for possible survivors, Snohomish County Fire District 21 Chief Travis Hots said yesterday evening. They found the body buried in the mud.
"We didn't see or hear any signs of life out there today," he said, adding that they did not search the entire debris field, only drier areas safe to traverse.
Despite that, Hots said crews were still in a "search and rescue mode. It has not gone to a recovery mode at this time."
He said the search would continue until nightfall, when conditions would become too dangerous.
Several people, including an infant, were critically injured in the mudslide that hit yesterday morning about 88 kilometres north of Seattle. About 30 homes were destroyed.
Rescuers' hopes of finding more survivors had been buoyed late Saturday when they heard people yelling for help from within the debris field, but they were unable to reach anyone. The mud was so thick and deep that searchers had to turn back.
The slide wiped through what neighbors described as a former fishing village of small homes, some nearly 100 years old. The neighbourhood "is not there anymore," Hots said.
Some of the missing may have been able to get out on their own, authorities said. The number unaccounted for could change because some people may have been in cars and on roads when the slide hit, Hots said.
Officials described the mudslide as "a big wall of mud and debris." It was reported about 18 metres deep in some areas.
Authorities believe the slide was caused by ground made unstable by recent heavy rainfall.
The slide blocked the North Fork of the Stillaguamish River. With the water pooling behind the debris, authorities worried about downstream flooding and issued an evacuation notice Saturday. The water had begun to seep through the blockage yesterday afternoon, alleviating some concerns.
Snohomish County officials said yesterday that residents could return home during daylight hours.
