Event narrative

On Wednesday April 14th 2010, at 07:49 local time, an earthquake of moment magnitude 6.9 struck the town of Jiegu (aka Gyêgu, Jyekundo, Yushu county town) and surrounding region in the Yushu county of the Yushu Tibetan autonomous prefecture in the southern part of China’s Qinghai province.

The earthquake occurred on the Ganzi-Yushu fault, with epicentre at 33.22°N, 96.67°E and focal depth of 18 km. A surface rupture was associated with this earthquake, which run for a distance of 33km and crossed less than 2 km south of Jeigu town. Jiegu town at the time had a population of 80,000 people and the strong shaking caused the collapse of more than 60% of the adobe low-rise housing in the town as well as the collapse of around one tenth of the town’s multi-storey buildings.

Overall impact

Authorities reported that 2698 people have been killed, while 270 remained missing presumably dead, 12,135 people were injured of which 2622 were hospitalized, with 1434 of them having serious injuries. The majority of the casualties occurred in Jiegu, an ancient market town in the Eastern Tibetan Plateau at altitude of 3700 metres, but many more smaller settlements in this sparsely inhabited mountainous region were also devastated including some culturally very important Tibetan temples and heritage sites.

At least 14% of the affected area’s school buildings collapsed, but thankfully the earthquake occurred just eleven minutes before these buildings were occupied by the students as classes were due to start.

Search and rescue activities were very efficient, as a regiment of the Chinese Army was stationed nearby Jiegu and acted promptly, as was the air lift of the seriously injured to hospitals outside this remote mountainous region. A critical role in this played the nearby Yushu Batang airport that was opened only eight and a half months earlier.

The earthquake left an estimated 100,000 people homeless and the Chinese government decided to entirely reconstruct the town of Jiegu with a timeframe of three years. Economic losses from this earthquake were estimated by the Chinese authorities at around 6.5 billion US$.
