Abstract

At 07:49, 14 April 2010, the Yushu Tibetan Autonomous Prefecture of Qinghai Province on the Qinghai-Tibet Plateau, China was struck by a magnitude 7.1 earthquake, with the epicenter located at 33.1° N and 96.7° E and at an altitude of 4300 m, and an epicentral intensity of Modified Mercalli scale IX. It was the first strong earthquake that struck the high-altitude, hypoxia-prone Tibetan plateau primarily inhabited by ethnic minorities since the founding of the People’s Republic of China, which has caused a huge loss of lives and property and adversely impacted the economic and social development of the area. The 2010 Yushu Earthquake was an earthquake disaster with the greatest destruction, widest spatial extent, and greatest difficulty for relief efforts in the history of Yushu, involving 19 townships in six counties of the prefecture. As verified by the Ministry of Civil Affairs, Ministry of Public Security, and the Yushu Prefecture Government, the earthquake killed 2698 people and caused government agencies to list 270 missing persons, who were mostly in Jiegu Town of Yushu County. The earthquake also caused a direct economic loss of RMB 44 billion Yuan. The severe environmental conditions in Yushu and limited infrastructural support for disaster relief to remediate the impacts on the earthquake victims were also rare in the history of earthquake disaster relief. This article focuses on the characteristics of the high-altitude Yushu Earthquake assessment and response, and summarizes the experiences and lessons of government and society in responding to this earthquake. The assessment of and response to the Yushu Earthquake will provide helpful references for high plateau earthquake response in the future.

Highlights

Summary

Introduction

Plateau, where the three large rivers in China (the Yangtze River, the Yellow River, and the Lancang River) originate. With a total area of 267,000 km and a population of 283,100 of which 95 percent are Tibetan (about a quarter of the Tibetan population in the province), the prefecture is the most heavily populated by Tibetans within the province. Jiegu Town of Yushu County, where the autonomous prefecture government is located, has a permanent population of about 80,000, which is 35 percent of the total population in the prefecture. Among this urban population, more than 98 percent are Tibetans. After introducing the earthquake event and making a brief assessment of its impact and the national response process, this article discusses and summarizes the experiences and lessons for government, society, and media in the region’s earthquake response
