Rescue workers sifted through tangled debris today for tens of thousands of victims buried or missing after the earthquake in China, where the death toll soared to more than 12,000 people in the hardest-hit province alone.
As night fell the day after the powerful 7.9 magnitude quake tore through urban areas and mountain villages across central China, state media said rescue workers had reached the epicenter in Wenchuan county, north of the Sichuan provincial capital, Chengdu.
State television quoted He Biao, director of the emergency office of the Aba government, as saying initial reports from soldiers who had to hike in showed there may be only 2,300 survivors from a population of 9,000 in Yinxiu, one of the affected towns.
The roads and bridges to another town in Wenchuan were all destroyed by the earthquake, and up to 80 per cent of the homes had collapsed. There was also no power in the county, he said.
The death toll figures were expected to jump sharply as rescuers worked their way through hard-hit towns at the epicenter.
In a massive government relief operation, some 20,000 soldiers and police arrived in the disaster area with 30,000 more on the way by plane, train, truck and on foot, the Defense Ministry told Xinhua. Rescue experts in orange jumpsuits extricated bloody survivors on stretchers from demolished buildings.
"Survivors can hold on for some time. Now it's not time to give up," Wang Zhenyao, disaster relief division director at the Ministry of Civil Affairs, told reporters in Beijing.
Xinhua said more than 12,000 had died in Sichuan province alone, but difficulties in accessing some areas meant the total number of casualties remained uncertain. In counties around one city near the epicenter, 18,645 people were buried, the agency said.
More than two dozen British and American tourists who were thought to be panda-watching in the area also remained missing.
Aftershocks rattled the region for a second day, sending people running into the streets in Chengdu.
Zhou Chun, a 70-year-old retired mechanic, was leaving quake-hit Dujiangyan city with a soiled, light-blue blanket draped over his shoulders.
"My wife died in the quake. My house was destroyed," he said. "I am going to Chengdu, but I don't know where I'll live."
Zhou and other survivors were pulling luggage and clutching plastic bags of food amid a steady drizzle and the constant wail of ambulances.
Just east of the epicenter, 1,000 students and teachers were killed or missing at a collapsed high school in Beichuan county — a more than six-story building reduced to a pile of rubble about two yards (meters) high, according to Xinhua. The agency said up to 5,000 people were killed and 80 percent of the buildings had collapsed in Beichuan alone.
At another leveled school in Dujiangyan, 900 students were feared dead. As bodies of teenagers were carried out on doors used as makeshift stretchers, relatives lit incense and candles and also set off fireworks to ward away evil spirits.
Elsewhere in Gansu province, a 40-car freight train derailed in the quake that included 13 gasoline tankers was still burning Tuesday evening, Xinhua said.
Premier Wen Jiabao, who rushed to the area to oversee rescue efforts, said a push was on to clear roads and restore electricity as soon as possible. His visit to the disaster scene was prominently featured on state TV, a gesture meant to reassure people that the Communist Party was doing all it could.
"We will save the people," Wen said through a bullhorn to survivors as he toured the disaster scene, in footage shown on CCTV. "As long as the people are there, factories can be built into even better ones, and so can the towns and counties."
The Ministry of Health issued an appeal for blood donations to help the quake victims.
Fifteen missing British tourists were believed in the area at the time of the quake and were "out of reach," Xinhua reported.
They were likely visiting the Wolong Nature Reserve, home to more than 100 giant pandas, whose fate also was not known, Xinhua said, adding that 60 pandas at another breeding center in Chengdu were safe.
Another group of 12 Americans also on panda-watching tour sponsored by the U.S. office of the World Wildlife Fund remained out of contact Tuesday, said Tan Rui, WWF communications officer in China.
Two Chinese-Americans and a Thai tourist also were missing in Sichuan province, the agency said, citing tourism officials.
The disaster comes less than three months before the start of the Beijing Olympics. The tragedy is just the latest event to tarnish the run-up to the event meant to showcase China's rise that has been marked by internal strife and criticism abroad of Beijing's human rights record.
In light of the quake, Beijing Olympics organizers said the torch relay will be simplified, downscaled and begin with a minute of silence Wednesday when a leg kicks off in the southeastern city of Ruijin.
The more somber relay will likely last until the torch's previously planned trip to the quake-hit areas next month, organizing committee spokesman Sun Wiede said, and people along the route will be asked for donations to help disaster victims.
Expressions of sympathy and offers of help poured in from across the world, and Chinese President Hu Jintao discussed the disaster in a phone call with U.S. President George W. Bush, state TV reported.
The Dalai Lama, the exiled spiritual leader who has been vilified by Chinese authorities who blame him for recent unrest in Tibet, offered prayers for the victims. The epicenter is just south of some Tibetan mountain areas that saw anti-government protests earlier this year.
The Chinese government said it would welcome outside aid. Russia was sending a plane with rescuers and supplies, the country's Interfax news agency reported.
But Wang, the disaster relief official, said international aid workers would not be allowed to travel to the affected area. While China has been slow at times to react to natural disasters, it usually has not lacked the manpower to eventually cope with them.
China's Ministry of Finance said it had allocated 860 million yuan (US$123 million; ¤80 million) in aid for quake-hit areas.
The quake was China's deadliest since 1976, when 240,000 people were killed in the city of Tangshan, near Beijing in 1976. Financial analysts said the quake would have only a limited impact on the country's booming economy.
Seismologists said the quake was on a level the region sees once every 50 to 100 years. The last time the Indian land mass crashed the Tibetan highlands into the Sichuan plane with such ferocity was 1933, when a magnitude 7.5 quake killed more than 9,300 people. Monday's quake resulted from the pent-up stress since then, experts said.
"It's more an issue of how long and how much stress has been built up in this region," said Amy Vaughn of the U.S. Geological Survey.
