MANILA, Philippines — Rescuers detected signs of life in an avalanche of garbage that killed at least four workers and left more than 30 others missing Thursday in a central Philippines landfill and plan to intensify search efforts, an official said Saturday.
Twelve workers have been rescued with injuries from the huge mound of garbage that collapsed among the low-slung buildings of a waste management facility in the village of Binaliw in Cebu City, authorities said.
Dozens of rescuers including police, firefighters and disaster-response personnel have raced against time to find more survivors in dangerous conditions in the rubble of twisted tin roofs, iron bars and combustible heaps of garbage and debris.
''Authorities confirmed the presence of detected signs of life in specific areas, requiring continued careful excavation and the deployment of a more advanced 50-ton crane, which is enroute with police escort,'' Cebu City Mayor Nestor Archival said in a statement.
''Safety of responders remains paramount due to hazards such as unstable debris and acetylene risks, prompting adjustments to the security perimeter and controlled access,'' Archival said.
The four dead, including an engineer and a female office worker, were all employees of the landfill and waste management facility with a staff of 110, according to the mayor and police.
The initial list of victims on Friday included two dead and 36 missing, which increased Saturday to four dead, according to Archival, who did not provide an updated nunber of people missing.
The cause of the collapse of the mountain of garbage remains unclear, but a survivor told The Associated Press on Friday that it happened in an instant without any warning despite fairly good weather at the time.
