As night fell, barefoot volunteers dragged a generator and stadium lights into a town cemetery, where nearly 200 freshly dug graves lay open like wounds in the red clay soil, waiting for some of the hundreds killed by torrential rains.

Funerals already had been held all day as a light rain persisted on Thursday - a sister laying her brother to rest, a man burying his one-year-old niece in a small white casket, a mother who cried her nine-year-old son’s name repeatedly as he was lowered into the earth.

Small, handmade white crosses identified only by numbers - the details would have to come later - dotted the desolate, sodden hilltop.

Dozens more funerals will come on Friday and 300 more graves will be dug on Saturday, said Vitor da Costa Soares, a city worker in charge of the cemetery.

“We’ll make room. We have to. We’ll stay up here until 10 p.m., midnight if we can, and we’ll be here at 6 a.m. tomorrow,” he said.

At least 476 people were known dead after heavy rains unleashed mudslides before dawn on Wednesday, burying people as they slept. Survivors started digging for friends and relatives with their bare hands, kitchen utensils, whatever they could find as they waited for help in remote neighbourhoods perched precariously on steep, washed-out hillsides.

In the remote Campo Grande neighbourhood of Teresopolis, now accessible only by a perilous five-mile (eight-kilometer) hike through mud-slicked jungle, family members pulled the lifeless bodies of loved ones from the muck. They carefully laid the corpses on dry ground, covering them with blankets.

A young boy cried out as his father’s body was found - “I want to see my dad! I want to see my dad!”

Flooding and mudslides are common in Brazil when the summer rains come, but this week’s slides were among the worst in recent memory. The disasters punish the poor, who often live in rickety shacks perched perilously on steep hillsides with little or no foundations. But even the rich did not escape the damage in Teresopolis, where large homes were washed away.

“I have friends still lost in all of this mud,” said Carlos Eurico, a resident of Campo Grande, as he motioned to a sea of destruction behind him. “It’s all gone. It’s all over now. We’re putting ourselves in the hands of God.”

In the same area, Nilson Martins, 35, carefully held the only thing pulled out alive since dawn- a pet rabbit that had somehow remained pristinely white despite the mud.

“We’re just digging around, there is no way of knowing where to look,” he said. “There are three more bodies under the rubble over there. One seems to be a girl, no more than 16, dead, buried under that mud.”

The hundreds of homes washed away in the neighbourhood were turned inside out, their plumbing and electrical wires exposed. Children’s clothes littered the earth, cars were tossed upside down into thickets. An eerie quiet prevailed as people searched for life. The sounds of digging, with sticks and hands, were occasionally punctuated by shouts as another corpse was located.

Conceicao Salomao, a doctor coordinating relief efforts at a makeshift refuge inside a gymnasium in central Teresopolis, said about 750 people were staying there on Thursday and about 1,000 people had sought treatment in the past day. One danger she worried about was leptospirosis, a waterborne bacterial disease.

“The hospitals around here are overflowing. The army and navy are setting up field hospitals to help,” she said.

Rio state’s Civil Defence department said on its website that 222 people were killed in Teresopolis, 214 in nearby Nova Friburgo and 40 in neighbouring Petropolis. It said about 14,000 people had been driven from their homes.

An additional 37 people had died in floods and mudslides since Christmas in other parts of southeastern Brazil - 16 in Minas Gerais state north of Rio and 21 in Sao Paulo state.

Nineteen-year-old Geisa Carvalho and her mother were awakened at 3 a.m. on Wednesday by a tremendous rumble as tons of muck slid down a sheer granite rock face onto their Teresopolis neighbourhood of Caleme.

The power was out, but by lightning flashes they could see the torrent of mud and water rushing just a few feet (meters) from their home - and the remnants of their neighbours’ houses that were swept far down a hill.

“We were like zombies, covered in mud, in the dark, digging and digging,” Ms. Carvalho said.

Nearly all the homes in their neighbourhood were swept to the bottom of a hill.

Just a few rescuers managed to hike to Caleme on Thursday and they had only shovels and machetes - not the heavier equipment needed to hunt for survivors. Residents said they had no food, water or medication, and many made the long walk for help to the centre of Teresopolis, about 40 miles (65 kilometers) north of Rio.

Morgues in the cities were full and bodies covered in blankets were laid in streets.

Officials said the area hit by slides had seen 10 inches (26 centimeters) of rain in less than 24 hours. More rain is forecast through the weekend.

President Dilma Rousseff flew by helicopter over the region on Thursday and the Health Ministry said it was sending seven tons of medications, enough to treat 45,000 people for a month.

Ms. Rousseff said the “destruction was an act of God” but she also said people died because homes were illegally built in areas prone to slides.

“We saw areas in which mountains untouched by men dissolved,” she told reporters in Rio after the flyover. “But we also saw areas in which illegal occupation caused damage to the health and lives of people.”
