TANAUAN, Philippines, Nov 16 (Reuters) - Long-delayed emergency supplies flowed into the typhoon-ravaged central Philippines on Saturday, reaching desperate families who had to fend for themselves for days, as the United Nations more than doubled its estimate of homeless to nearly two million.

The aid effort was still patchy, with relief officials reporting a surge in desperate, hungry survivors trying to leave the coastal city of Ormoc, 105 km (65 miles) west of Tacloban, the worst-affected major city.

More than a week after Typhoon Haiyan killed at least 3,633 with tree-snapping winds and tsunami-like waves, hundreds of international aid workers set up makeshift hospitals and trucked in supplies. Helicopters from a U.S. aircraft carrier ferried medicine and water to remote, battered areas.

Residents of Tanauan, a fishing town about 15 km (9 miles) southeast of Tacloban, said they only started receiving substantial aid on Friday after being forced to survive on biscuits and dispose of dead bodies on their own for days.

More than 60 people were buried behind the municipal office in the district of 50,000 people. Down the road, dozens of corpses were interred under a roundabout.

"I think (the response) was quite slow. This town was isolated. Media didn't come here. We were out of circulation for three days," said Penny Tecson, the wife of the district's mayor. She was running the recovery operation while her husband, Pel Tecson, was in Tacloban to coordinate the district's first large-scale delivery of aid from the national government.

In one ward of Tanauan, neighborhood chief Cecilio Yepes Jr. estimated his community lost nearly 10 percent of its 1,176 residents. Here, the storm surge has transformed an entire swampy plain into a rubbish pile of trees and debris. Locals have recovered and buried 30 bodies. Another 98 remain somewhere in the vast wasteland that stretches on either side of the road.

At least 800 people died in the district of Palo, which lies between Tanauan and Tacloban, national authorities said.

In Tacloban, work crews and heavy equipment cleared debris from roadsides, but side streets remained piled with the sodden, tangled remains of homes which city officials fear could reveal hundreds more bodies when they are eventually cleared.

There are 1,179 people missing, according to the national count. The official death toll only rose by 12 on Saturday, giving hope that initial local estimates of 10,000 dead were overblown.
