Advertisement At least 300 people have died and thousands are feared hurt after a magnitude-6.9 earthquake struck China's Qinghai province, officials say. The powerful tremor hit remote Yushu county, 500km (310 miles) south-west of provincial capital Xining, at 0749 (2349 GMT), at a shallow depth of 10km. Chinese TV showed wrecked buildings and people scrabbling through debris. Officials ordered rescue crews and supplies to Yushu, but the area is hundreds of miles from an airport.

History of deadly earthquakes "Soldiers have been dispatched to save the people buried in the collapsed houses," local official Huang Limin was quoted as saying by China's state news agency Xinhua. One official told journalists more than 85% of buildings in Jiegu town near the epicentre had collapsed. "The streets in Jiegu are thronged with panic - injured people, with many bleeding in the head," Zhuo Huaxia told Xinhua. "Many students are buried under the debris due to building collapse at a vocational school. "I can see injured people everywhere. The biggest problem now is that we lack tents, we lack medical equipment, medicine and medical workers." Many of the buildings in Yushu, a county with a largely Tibetan population of about 80,000, were thought to be made from wood. In 2008, a huge quake struck neighbouring Sichuan province which left 87,000 people dead or missing. Quake-prone region Karsum Nyima, from Yushu county's TV station, told China's state-run CCTV that school students had been assembled in outside playgrounds, although school buildings had not collapsed. ANALYSIS Michael Bristow, BBC News, Beijing The earthquake struck just before 0800 local time - when many people were still at home. It was followed by three aftershocks. Some media reports say most buildings in the town near the epicentre fell down. Grainy pictures on Chinese television showed rescuers pulling at the rubble of one collapsed structure. Soldiers have been sent to the area to help with the rescue. The earthquake happened in a remote and sparsely populated area on the Tibetan plateau. The area is regularly hit by earthquakes. "In a flash, the houses went down. It was a terrible earthquake. In a small park, there is a Buddhist tower and the top of the tower fell off," he said. "Everybody is out on the streets, standing in front of their houses, trying to find their family members." Zhuo De, an ethnic Tibetan resident of Yushu, who spoke by phone from the capital of Qinghai province, Xining, said there could be many more casualties. "The homes are built with thick walls and are strong, but if they collapsed they could hurt many people inside," he said. The remote high-altitude region is prone to earthquakes, but officials from the US Geological Survey said this was the strongest quake within 100km of the area since 1976. Residents of Yushu fled their homes after the quake The region, which is home to ethnic Mongolians and Tibetan farmers and herdsmen, is dotted with coal, tin, lead and copper mines. After the Sichuan quake, five million people were left homeless, and officials estimated rebuilding work would take at least three years. The government later punished people who had compiled lists of the victims and had suggested shoddy school-building was partly to blame for the high death toll. Are you in the area?

Epicentro del terremoto.



Al menos cuatrocientas personas fallecieron y otras 10,000 resultaron heridas por un terremoto de magnitud 7,1 y sus posteriores réplicas que azotaron al condado de Yushu, en las remotas y montañosas áreas al sur de la provincia de Qinghai, en el oeste de China.

Un funcionario de la ciudad de Gyêgu, que fue uno de los lugares más afectados, dijo que "definitivamente el número de muertos aumentará."

El Servicio Geológico de los Estados Unidos informo que el temblor comenzó a las 07,49 hora local (23:49 UTC). El epicentro se situó a 240 kilómetros al norte-noroeste de Qamdo, Xizang, y 375 kilómetros al sur-sureste de Golmud, Qinghai, con una profundidad de diez kilómetros. El centro de terremotos de China, sin embargo, contradice las estadísticas del USGS, poniendo la magnitud del terremoto en 7,1.

El Servicio Geológico de los Estados Unidos también informó que hubo una réplica de 5,8 grados de magnitud que sacudió la misma zona alrededor de una hora y media más tarde, a las 09,25 hora local (01:25 UTC).

El director de noticias de la estación de televisión Yushu del condado, que fue testigo del terremoto, se refirió a la cadena estatal CCTV sobre el incidente, diciendo que "En un instante, las casas se vinieron abajo. Fue un terrible terremoto. En un pequeño parque, hay una torre budista y la parte superior de la torre se cayó." Dijo que los residentes huyeron después de que los temblores comenzaron.

"Todo el mundo está en la calle, de pie en frente de sus casas, tratando de encontrar a sus familiares".

La meseta donde se produjo el terremoto, es comúnmente asechada por temblores, sin embargo, rara vez hay muchas bajas debido a su lejanía y poca población. Sin embargo, en mayo de 2008 un terremoto de 8,0 grados de magnitud se suscitó cerca de Sichuan y mató a 80.000 personas.
