On April 14, 2010, an earthquake reaching 7.1 Richter scale struck Jiegu Town of yushu. More than 2 698 people were confirmed dead, and 12 135 were injured, of which 1 434 were severely injured. Rescue operation was carried out soon after the disaster; however, the rescue teams face great challenges of altitude hypoxia, freezing temperature and very bad weather. Thus, 1 434 severe injuries were rapidly transported airlifted to hospitals in Xining and neighboring provinces for effective treatment. The extremity trauma （49.9 % ） was the most common patteru of injuries. Asphyxia （40.8 % ） was by far the most important reason for death. A high incidence of acute altitude illness in the lowland rescuers was a special medical problem during the highest earthquake in yushu. We have learned more lessons from yushu earthquake.

Geodesy and Geodynamics 2012年第4期3卷 1-6页

作者： Zhu Yiqing Liu fang Cao Jianping Zhao Yunfeng State Key Laboratory of Geodesy and Earth's Dynamics Institute of Geodesy and GeophysicsChinese Academy of Sciences Second Crust Monitoring and Application Center China Earthquake Administration earthquake Administration of Shanxi Province

Absolute and relative gravity observations from 1998 -2010 from the China Crustal Movement Ob- servation Network, a major national scientific project, have been used to model the gravity field and its varia- tions associated with the April 14, 2010 Ms7.1 yushu earthquake. The evolution of the regional gravity field and its relationship with seismicity before and after the yushu earthquake are studied. The observed gravity changes are closely related to the active Ganzi-yushu Fault, and gravity measurements can be used to observe the migration of material accompanying active faults and crustal tectonics. The dynamic variation of the gravity field reflects its evolution prior to and during the yushu earthquake. The gravity measurements near its epicen- ter are as large as 80 × 10-s m/*** they show wave-like increases with time prior to the yushu earth- quake.

作者： Zhang Zhijin Tang Guibo He Xiaofen Zhang Ming Wu Dangjie Geng Gasongbao Department of Radiology Qinghai Provincial People's Hospital Department of Radiology Tibetan Autonomous Prefecture of Yushu

The purpose of this study was focused on the imaging features of the chest trauma and its relation to clinical characteristics. All the injured patients were from the yushu earthquake areas on days April 14 - 23,2010. After an initial treatment,the injurers were rapidly transported from yushu at an altitude of 4 000 m via air to Xining at 2 260 m within 6~8 h,and promptly admitted to Qinghai Provincial People’s Hospital. A total of 130 wounded injurers who had high suspicion of chest injuries all had examinations of Chest X-ray and computed tomography(CT)images. Of them 63 injurers presented at least one of the features of the chest trauma in imaging with a positive rate of 48.5 %. Of these,37 cases (28.5 %) were multi-system with multiple injuries ,33 cases (25.4 %) were chest trauma with multi-injury types,which included thoracic fractures in 54 cases (85.7 %),pleural injury in 56 cases (88.9 %),lung injury in 54 cases (85.7 %),lungs complications in 37 cases (58.7 %),and extrapulmonary complications of 35 cases (55.6 %). The radiological data were analyzed retrospectively. The features of chest trauma in yushu earthquake,the complications of chest injuries,and the relation between imaging findings and clinical manifestations,as well as the differences of chest trauma between yushu earthquake and Wenchuan earthquake were discussed in detail.

Engineering Sciences 2013年第2期11卷 5-16页

作者： Wu Tianyi High Altitude Medical Research Institute High Altitude Medical Research Center Tibet University

On April 14,2010,an earthquake reaching Richter scale 7.1 struck Jiegu Town of yushu,a mountain rescue operation promptly launched. All injurers had a direct assess to take medical care,and were immediately rescued and rapidly evacuated by air to Xining and Golmud at lower altitudes and admitted to advanced hospitals. Almost all of the injurers have been completely recovered. yushu earthquake was one of the highest earthquakes in the world,with a high incidence of acute altitude illness,which was observed in about 80 % of the lowland rescuers at an altitude of 4 000 m."Rescue the rescuers"became the major task of Qinghai-Tibetan rescue teams,all the severe patients were rapidly descended to Xining and treated promptly and effectively. The outcome was excellent,all patients survived. After the earthquake,it is a long and arduous task to reconstruct what has been destroyed. Medical teams continue to work in the yushu earthquake area because about 30 000 workers and carders are now here for rebuilding the earthquake center. Thus the prevention and treatment of altitude illness are still critical tasks for medical teams. Although all the fights are successful,there are more experiences and lessons we have learned from the medical mountain rescue during the earthquake and the reconstruction,and reports here are to sum up our experiences from the medical mountain rescue operation in yushu earthquake and draw the lessons that we should learn. With the increasing of earthquake probability occurring in the Qinghai-Tibetan Plateau,we also should prepare against earthquake disasters and for further rescue training in the high mountains.

During the yushu earthquake on April 14,2010,a large number of rescuers from sea level or lowlands ascended to the quake areas very rapidly or rapidly less than 24 h. However,yushu earthquake is the highest quake in the world at altitudes between 3 750 m and 4 878 m where is a serious hypoxic environment. A high incidence of acute altitude illness was found in the unacclimatized rescuers;the mountain rescue operation changed as "rescue the rescuers". Lesson from the yushu earthquake is that the occurrence of acute altitude illness may be closely related to the ascent schedules. This prompted us to study the relationship between ascent rate and the incidence and severity of acute altitude illness;five different groups were compared. The first group was 42 sea level male young soldiers who ascended to quake area very rapidly within 8 h at 4 000 m;the second group was 48 sea level male young soldiers who ascended to 4 000 m rapidly less than 18 h;the third group was 66 acclimatized medical workers from 2 261 m who ascended to 4 000 m rapidly within 12 h;the fourth group was 56 Tibetan medical workers from 2 800 m who ascended to 4 000 m rapidly within 8 h;the fifth group was 50 male sea level workers who ascended to 4 000 m gradually over a period of 4 d. The results showed that the sea level rescuers ascended to 4 000 m very rapidly or rapidly had the highest incidence of acute mountain sickness (AMS) with the greatest AMS scores and the lowest arterial oxygen saturation (SaO2);the sea level workers ascended to 4 000 m gradually had moderate incidence of AMS with moderate AMS scores and SaO2 values;whereas the acclimatized and adapted rescuers had the lowest incidence of AMS,lowest AMS scores and higher SaO2;especially none AMS occurred in Tibetan rescuers. AMS score is inversely related to the ascent rate (r=-0.24,p< 0.001). Additionally,acute altitude illness is significantly influenced by altitude acclimatization. The ascent rate is inversely re- lated to the perio

A necklace of pearl in high altitude medicine and hypoxic physiology in yushu earthquake

引用

Engineering Sciences 2013年第2期11卷 2-4页

作者： Fan Ming Institute of Basic Medical Sciences Academy of Military Medical Sciences

During yushu earthquake,a large number of rescuers flocked to the mountainous quake areas. Under such a very specific circumstance,a high incidence of acute altitude illness was observed in rescuers who rapidly traveled from near sea level to an altitude of 4 000 m. It is evident that acute altitude illness leads to a significant human and economic toll,and also seriously influences the mountain rescue operation. So what does this teach us about mountain rescue in yushu? Professor Wu Tianyi and many other authors collected shining points of the experiences and drew the lessons from the yushu earthquake into this special issue in Engineering Sciences which is like to thread pearl beads for a necklace. What readers learn from this special issue will have implications for the health and well-being of all high altitude populations all over the world.

Modeling of co- and post-seismic surface deformation and gravity changes of M W 6.9 yushu, Qinghai,earthquake

引用

earthquake Science 2011年第2期24卷 177-183页

作者： Chengli Liu Bin Shan Yong Zheng Ying Jiang Xiong Xiong Key Laboratory of Dynamic Geodesy Institute of Geodesy and Geophysics Chinese Academy of Sciences Wuhan 430077 China Graduate University of Chinese Academy of Sciences Beijing 100049 China

Based on the elastic dislocation theory, multilayered crustal model, and rupture model obtained by seismic waveform inversion, we calculated the coand post-seismic surface deformation and gravity changes caused by the yushu M W 6.9 earthquake occurred on April 14, 2010. The observed GPS velocity field and gravity field in yushu areas are disturbed by the coand post-seismic effects induced by yushu earthquake, thus the theoretical coand post-seismic deformation and gravity changes will provide important modification for the background tectonic movement of yushu and surrounding regions. The time relaxation results show that the influences of yushu earthquake on yushu and surrounding areas will last as long as 30 to 50 years. The maximum horizontal displacement, vertical uplift and settlement are about 1.96, 0.27 and 0.16 m, respectively, the maximal positive and negative value of gravity changes are 8.892×10-7 m·s-2 and -4.861×10-7 m·s-2 , respectively. Significant spatial variations can be found on the coand post-seismic effects： The co-seismic effect mainly concentrates in the region near the rupture fault, while viscoelastic relaxation mostly acts on the far field. Therefore, when using the geodetic data to research tectonic motion, we should not only consider the effect of co-seismic caused by earthquake, but also pay attention to the effect of viscoelastic relaxation.
