Real, Philippines ? Helicopters delivered food to survivors and picked up casualties Friday as flash floods began to recede in the northern Philippines, revealing the magnitude of a disaster triggered by back-to-back storms that killed more than 650 people and left nearly 400 missing.

Soldiers who reached an isolated Pacific Ocean village in Aurora province reported finding about 30 dead. In the worst-hit town of Real, in nearby Quezon province, TV images showed bodies buried under mud and debris with only the soles of their feet visible.

Flash floods and landslides triggered by back-to-back storms that lashed the northeastern Philippines had killed more than 650 people by Friday, with nearly 400 still missing, military officials said.

Some 170,000 have fled their homes for higher ground while health authorities urged local officials to bury the dead quickly.

President Gloria Macapagal Arroyo appealed to the nation to “come together … (and) reach out to those who need help.”

“We need one great heave to deliver the relief supplies, find the missing, rescue the isolated, feed the hungry and shelter the homeless,” Arroyo said.

The brunt of the devastation was wrought by a tropical storm that blew through late Monday, killing at least 527 people, military Chief of Staff Gen. Efren Abu said Friday.

Hardest hit was Quezon province, where 484 bodies have been recovered and 352 people remain missing, he said.

Typhoon Nanmadol then struck the same region late Thursday.

Maj. Gen. Romeo Tolentino, the regional military commander, said landslides were blocking the road to the coastal village of Dumingan.

“There were landslides and our civilians were going hungry,” he said. “Some were wet. So they are really pitiful.”
