At least two person is dead and 31 others injured, including 10 seriously, after an earthquake measuring 5.1 degrees on the Richter scale jolted Yanjin County, Zhaotong City, Southwest China's Yunnan Province, at 1:51 p.m Friday.

Earlier reports said the death toll was two proved erroneous when it was discovered that the same victim had been counted twice, a spokesman with the Zhaotong municipal government told Xinhua.

"Power, communications and traffic in the quake-hit areas have all been resumed," said Yang Jiahua, vice mayor of Zhaotong.

The official said medical workers have arrived in the affected areas for rescue and epidemic prevention.

Yunnan Provincial Civil Affairs Bureau has sent officials and earthquake experts to direct relief efforts in quake-hit areas.

Yin Liyuan, vice director of the bureau, said 400 tents were already on the way to the quake-hit areas.

Vice governor Kong Chuizhu urged local departments to assess the situation in affected areas and evacuate people to safe places.

Damage to homes and economic losses are being calculated.

The epicenter of the quake was located 28 degrees north and 104.2 degrees east of the township of Dousha, 570 kilometers from Kunming, the provincial capital.

A Xinhua correspondent in Chengdu, capital of neighboring Sichuan Province, said he felt the quake.

Cheng Lianyuan, CPC secretary of Yanjin County committee, said the township was 26 kilometers from the county, adding, "The quake was strongly felt in the county. Some big rocks rolled down from the mountains and destroyed many parts of the road between the township and the county".

The work team from Yanjin was stuck on the damaged road, which was being repaired by more than 50 workers.

Yet Zhang Yan, head of the county's publications department, had already visited the township.

"Quite a number of homes in Dousha Township were damaged and the streets are littered with tiles and bricks. Many residents stayed outdoors for fear of aftershocks," she said.

Officials of the township were investigating casualties and losses caused by the quake in the villages, Zhang said.

The earthquake was also strongly felt in the neighboring county of Daguan, 40 kilometers from the epicenter.

Zheng Yi, head of the county, said they were counting casualties and losses.

Yanjin County is located on the Yunnan-Guizhou Plateau and has a population of 350,000.

An earthquake measuring 5.1 on the Richter Scale hit Yanjin and neighboring Daguan county on July 22, killing 22 and injuring 106 people.

The quake toppled more than 1,400 houses and damaged 38,000 others in 13 townships of the county as most houses in Yanjin are built on hillside and therefore vulnerable to earthquakes.

Yanjin is located on an earthquake belt, where at least nine major quakes were recorded, the strongest of which was measured at 7.1 on the Richter scale.
