"We were passing by the Jushui town, and we saw a huge landslide," a man from Mianzhu City, about 60 kilometers to quake center Wenchuan, told Xinhua over the phone. He was on his way to visit a friend in Anxian County in the northeast Monday afternoon.
"Rocks buried many houses down at the foot of the hill, and some of the vehicles on the road were buried too. I saw the rear of a car and the wheels of another. Several people were crying for help and some were bleeding," he said.
A nurse at the forestry center in the Aba prefecture asked reporters to take photos of a boy with scratches on his face to help find his relatives. The nurse said his parents were suspected to have died in the quake.
The quake, with a magnitude of 7.8, struck Sichuan, including the capital Chengdu, around 2:30 p.m. on Monday. The epicenter of the quake was in Wenchuan, about 159 kilometers northwest of Chengdu.
"Wenchuan is located at a major fault line. This was really big-scale fracture, and the destruction was grave," said Che Shi, an official with the China Seismological Bureau.
Local authorities said the quakes have left more than 8,500 people dead in Sichuan alone. Water, electricity and transportation were seriously affected in the province. The massive quake is believed to be the deadliest quake to strike China since the Tangshan earthquake in 1976, which claimed 242,000 lives.
By Monday midnight, at least 24,000 troops have arrived by air in the quake-hit zones for rescue operations, and another 10,000 were on the way by rails.
In Dujiangyan City, about 100 kilometers from Wenchuan, some of the residential buildings seemed to have been axed, and refrigerators, television sets and other furniture were left rumbled in the debris.
In Shiyou Road in Dujiangyan, Xinhua reporters saw on Monday afternoon at least four buildings flattened, and people were digging frantically into the wreckages. At least 50 schoolchildren were confirmed dead at a school in the city.
Deep into the night, many residents in Chengdu spent the nights in streets, and cars queue at some of the petrol stations, as people fear shortage of petrol.
Rail traffic has been partially resumed and jammed or disrupted mobile communications were returning to normal.
The Sichuan Provincial health department has sent 24 medical teams to Wenchuan, Mianzhu and Shifang, worse hit than capital Chengdu. More than 100 helicopters were sent to Mianyang, Deyang and Dujiangyan to transport the injured.
The Ministry of Health, the neighboring municipality Chongqing and the army have also dispatched medical workers to Sichuan.
Major earthquakes not likely hit China in near future
Major earthquakes will not likely hit China again in near future, the China Seismological Bureau (CSB) said here on Monday.
Experts with the CSB concluded late on Monday night that apart from the regions near the epicenter of Monday's earthquake, which is located 31.0 degrees north latitude and 103.4 degrees east longitude, the rest of Sichuan Province and the country is not likely to be hit again soon.
The CSB has strengthened earthquake monitoring, the bureau said.
