Sensors picking up signals near school

Rescuers are hopeful, but no one has been pulled out alive since a few hours after the disaster Friday.
GUINSAUGON, Philippines (AP) -- Rescue workers refused to give up hope of finding survivors in an elementary school buried by up to 100 feet of mud, digging into the night Monday after detecting what the provincial governor called "signs of life."
Sounds of scratching and a rhythmic tapping were picked up by seismic sensors and sound-detection gear brought in by U.S. and Malaysian forces.
"To me, that's more than enough reason to smile and be happy," South Leyte Gov. Rosette Lerias said. "The adrenaline is high ... now that we have seen increasing signs of life."
Still, it was hard to imagine survivors under the wet muck nearly four days after a mountainside collapsed and covered the farming village of Guinsaugon, killing up to 1,000 people. No one has been pulled out alive since just a few hours after the disaster Friday morning.
Bodies, but no survivors
The search has focused on the school because of unconfirmed reports that some of the 250-300 children and teachers may have sent cell phone text messages to relatives soon after the disaster Friday.
Under the glare of generator-powered lights, a multinational group of troops and technicians used high-tech gear like seismic sensors and sound- and heat-detection equipment alongside shovels and rescue dogs. They finally halted about 3 a.m. today until daybreak.
A U.S. military spokesman said late Monday that U.S. Marines digging at the site had found bodies, but no survivors.
"I asked had they received or found any type of survivors, and the answer was no," U.S. Marine Capt. Burrell Parmer said after speaking to the commander of U.S. forces at the disaster site.
The statement discounted an earlier report by Philippine Interior Undersecretary Marius Corpus that U.S. Marines had found 50 survivors. There was no immediate explanation for how the false report had spread.
"There is a lot of rubble, a lot of large boulders," Parmer said. "On some sides near the river, it's very moist, very soft soil, and you can get stuck up to ... your waistline if you're not careful."
Definite signals
Still, the Marines were eager to discover the origin of sounds detected by seismic sensors.
"The farther down we went, the signals grew stronger," U.S. Marine Lt. Richard Neikirk said as he pointed to a spot under a big boulder.
A Malaysian team using sound-detection gear picked up noises, too.
"We have a sound," said Sahar Yunos of the Malaysia Disaster and Rescue Team. "Knocking, something like that."
A rescue dog also stopped three times at one spot away from where rescue workers were digging.
There was no visible sign of the school. Rescue workers were digging at two places -- one where the school was believed to have sat close to the mountain, the other 200 yards down the hill, where the landslide could have carried it.
Dozens of U.S. Marines and Philippine soldiers, along with local miners, were digging in a watery, boulder-strewn spot around the school's original site, using shovels on the muck and moving it with body bags, while draining the murky water in large bottles.
