1Source models for the 2016 Mw6.0 Hutubi earthquake, Xinjiang,China: A possible reverse event显示文摘South and north-dipping nodal planes from the U.S. Geological Survey moment tensor solution were used to invert global teleseismic body waves to reveal the source rupture process of the December 8,2016, Mw6.0 Hutubi earthquake. The results show that a compact pattern is the main feature of this event for only one main slip zone located at the hypocenter for both models. The slip distributions are dominated by a nearly pure-thrust fault, and there is no apparent surface rupture. The inversion revealed that the slip zone extends 10 km along strike and 12 km along dip. The released total seismic moment was about 9.0 × 10^(17) Nm, corresponding to a magnitude of Mw6.0. It is difficult to solve for a best-fit rupture plane due to the sample slip pattern without obvious rupture directivity. This makes the farfield teleseismic data not sensitive enough to determine the fault geometric parameters. The source model of the reverse north-dipping plane fits well with the observed waveforms, and the results of the aftershock relocation outline a trend of north-dipping profiles, indicating the possibility of a reverse event. The inverted normal fault beneath the Qigu fold, interpreted by geological and seismic studies,may be the seismogenic fault for this reverse event.Gang Liu Xuejun Qiao Wei Xiong Yu Zhou Zhaosheng Nie Chuanjia Xia 2017Geodesy and Geodynamics2017,8,5:4
2Near-field surface deformation during the April 20,2013,Ms7.0 Lushan earthquake measured by 1-Hz GNSS显示文摘The April 20,2013,Ms7.0 Lushan earthquake was successfully recorded by closely spaced Continuous Global Positioning System (CGPS) stations owned by the Crustal Movement Observation Network of China (CMONC).The 1-Hz GNSS data from eight CGPS stations,which are located between 30 km and 200 km from the hypocenter,were processed within quasi-real-time.The near-field surface deformation indicated the following characteristics:the near-field movements were limited to several centimeters;the peak of the deformation wave was significantly larger than the static permanent offset;at the beginning of the event,the north wall of the fault moved to the southeast as the south wall moved to the southwest;station SCTQ,which was the closest station to the hypocenter at 30 km,had the largest static permanent displacement of 2 cm;the peaks of the deformation waves were 1.5 cm,5 cm and 3 cm,to the east,the south and vertically upward,respectively;and the peaks of velocity and acceleration,derived from the deformation,were 3.4 cm/s and 5.3 cm/s2,respectively.Liu Gang Zhao Bin Zhang Rui Huang Yong Wang Jun Nie Zhaosheng Qiao Xuejun Tan Kai 2013Geodesy and Geodynamics2013,4,2:3
3Genomic Surveillance for SARS-CoV-2 Variants of Concern from Imported COVID-19 Cases-the Mainland of China,2021显示文摘Introduction:After the epidemic in Wuhan City was brought under control in 2020,local outbreaks of coronavirus disease 2019(COVID-19)in the mainland of China were mainly due to imported COVID-19 cases.The ongoing evolution of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has continued to generate new variants.Some have been designated as variants of concern(VOCs)by the World Health Organization(WHO).To better assess the role of imported SARS-CoV-2 surveillance and the prevalence of VOCs in 2021,the genomic surveillance data of SARS-CoV-2 from imported COVID-19 cases of 2021 in the mainland of China were analyzed.Methods:The analyses included the number of sequence submissions,time of sequence deposition,and time of detection of the VOCs in order to determine the timeliness and sensitivity of the surveillance.The proportions of VOCs were analyzed and compared with data from the Global Initiative of Sharing All Influenza Data(GISAID).Results:A total of 3,355 sequences of imported cases were submitted from 29 provincial-level administrative divisions,with differences in the number of sequence submissions and median time of sequence deposition.A total of 2,388 sequences with more than 90%genomic coverage were used for lineage analysis.The epidemic trend from Alpha to Delta to Omicron in imported cases was consistent with that in the GISAID.In addition,VOCs from imported cases were usually identified after WHO designation and before causing local outbreaks.Conclusions:The global distribution of SARSCoV-2 VOCs changed rapidly in 2021.Robust genomic surveillance of the imported SARS-CoV-2 in the mainland of China is of great significance.Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the etiological agent of coronavirus disease 2019(COVID-19),is constantly mutating under the different circumstances of global transmission(1).The emerging SARS-CoV-2 variants may have potential adverse impacts on epidemic traits and severity.To some extent,it is also capable of escaping natural and vaccine-induced immunity(2–3).Some of them were designated as variants of concern(VOCs)by the World Health Organization(WHO)(4).Therefore,robust surveillance is essential to assess the evolution of viruses in real time.After the epidemic in Wuhan City was brought under control in 2020,several COVID-19 outbreaks in the mainland of China have been proven to relate to SARS-CoV-2 contaminated cold-chain products(5–7),while most were caused by transmission through imported cases on flights,at isolation facilities,or in designated hospitals(8–9).Therefore,genomic surveillance for SARS-CoV-2 from imported cases is of great significance for monitoring the risk of different variants that were imported into the mainland of China,assessing the risk of importation-associated domestic spread,and helping guide public health interventions.On March 17,2020,the China CDC released a notice and launched genomic surveillance for SARS-CoV-2 from imported COVID-19 cases nationwide.The laboratories of provincial CDCs were required to conduct SARS-CoV-2 whole-genome sequencing for samples from imported cases and submit the genomic sequences to the China CDC in time.This study includes the analysis of genomic surveillance data of imported SARS-CoV-2 cases of 2021 from the mainland of China.Yenan Feng Xiang Zhao Zhixiao Chen Kai Nie Zeyuan Yin Ying Xia Ji Wang Peihua Niu Ruhan A Lili Li Dayan Wang Wenjie Tan Xuejun Ma Shiwen Wang Huanyu Wang George F.Gao Cao Chen Wenbo Xu 2022China CDC weekly2022,4,31:1

5Surveillance and Analysis of SARS-CoV-2 Variant Importation—China,January–June 2022显示文摘Introduction:The severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant is the dominant circulating strain worldwide.To assess the importation of SARS-CoV-2 variants in the mainland of China during the Omicron epidemic,the genomic surveillance data of SARS-CoV-2 from imported coronavirus disease 2019(COVID-19)cases in the mainland of China during the first half of 2022 were analyzed.Methods:Sequences submitted from January to July 2022,with a collection date before June 30,2022,were incorporated.The proportions of SARS-CoV-2 variants as well as the relationships between the origin and destination of each Omicron imported case were analyzed.Results:4,946 sequences of imported cases were submitted from 27 provincial-level administrative divisions(PLADs),and the median submission interval was within 1 month after collection.In 3,851 Omicron sequences with good quality,1 recombinant(XU)and 4 subvariants under monitoring(BA.4,BA.5,BA.2.12.1,and BA.2.13)were recorded,and 3 of them(BA.4,BA.5,and BA.2.12.1)caused local transmissions in the mainland of China later than that recorded in the surveillance.Omicron subvariants dominated in the first half of 2022 and shifted from BA.1 to BA.2 then to BA.4 and BA.5.The percentage of BA.2 in the imported SARS-CoV-2 surveillance data was far higher than that in the Global Initiative on Sharing All Influenza Data(GISAID).The imported cases from Hong Kong Special Administrative Region,China,accounted for 32.30%of Omicron cases sampled,and 98.71%of them were BA.2.Conclusions:The Omicron variant showed the intra-Omicron evolution in the first half of 2022,and all of the Omicron subvariants were introduced into the mainland of China multiple times from multiple different locations.Yenan Feng Xiang Zhao Zeyuan Yin Changcheng Wu Zhixiao Chen Kai Nie Ruhan A Lili Li Peihua Niu Ji Wang Yuchao Wu Shiwen Wang Dayan Wang Wenjie Tan Huanyu Wang Xuejun Ma George FGao Cao Chen Wenbo Xu 2022China CDC weekly2022,4,50:1

8Development of a PDRA Method for Detection of the D614G Mutation in COVID-19 Virus—Worldwide,2021显示文摘ABSTRACT Background:COVID-19 infection is a major public health problem worldwide,and the D614G mutation enhances the infectivity of COVID-19.Methods:A probe-directed recombinase amplification(PDRA)assay was discussed to detect the D614G mutation at 39℃for 30 min.The sensitivity,specificity,and reproducibility of the PDRA were evaluated by D614 and G614 recombinant plasmids.The clinical performance of PDRA assay was validated by testing of 53 previously confirmed COVID-19 positive RNAs and 10 negative samples.Direct sequencing was carried out in parallel for comparison.Result:With good reproducibility and specificity,the PDRA assay worked well with the concentration in the range of 103–107 copies/reaction.Compared with direct sequencing as a reference,the recombinase-aided amplification(RAA)assay obtained 100%sensitivity and 100%specificity using clinical samples.Ziwei Chen Xinxin Shen Ji Wang Xiang Zhao Yuan Gao Ruiqin Zhang Jinrong Wang Leping Liu Xinmin Nie Xuejun Ma 2021China CDC weekly2021,3,21:1
9Coulomb stress evolution along the Kongur Extensional System since 1895 and present seismic hazard显示文摘The present-day tectonic activities on the northeastern margin of the Pamir Plateau are mainly E-W oriented extensions, among which the Kongur Extensional System(KES) plays an important role in the internal expansion of the Pamir. As the largest earthquake since Taxkorgan earthquakes in 1895 and 1896, the Aketao earthquake occurred on the Muji fault on the northern portion of the KES in 2016. Since then, the trend of seismic activities along the KES has been paid much attention to. Based on the visco elastic layered lithosphere model, we calculate the co-seismic and post-seismic stress changes caused by five historical earthquakes on the KES and its adjacent areas since 1895, and analyze the interaction among strong earthquakes. The results show that all of the historical earthquakes after 1895 occurred in the areas where the co-seismic and post-seismic Coulomb stress increased. Coulomb stress loading at the hypocenters of the 1896 Taxkorgan earthquake, the 1974 Markansu earthquake and the 2016 Aketao earthquake were 0.251 MPa, 0.013 MPa and 0.563 MPa, respectively. The three earthquakes were catalyzed by such variations. The historical earthquakes increased the stress state on most segments of the Southern Kungai Mountain fault and Kongur fault along the KES. In particular, we can identify 2 visible earthquake gaps with increasing seismic hazard formed on the Qimugan segment and Bulunkou segment of the KES. The Qimugan section and the Bulunkou section are located at the fault transition zone with concentrated stress and high extension rate, so great attention should be paid to their seismic hazard at present day.Wei Xiong Xuejun Qiao Gang Liu Wei Chen Zhaosheng Nie 2019Geodesy and Geodynamics2019,10,1:1

12Study on the Cap Rock Deformation of Hutubi Underground Gas Storage by GPS Observations显示文摘The deformation responses of surface cap rocks of Underground Gas Storage( UGS) in Hutubi,Xinjiang during gas injection and production were investigated with the GPS data recorded by the deformation monitoring network,which includes 13 observation sites. The time series of three-dimensional deformation of the surface cap rocks was obtained in the UGS operation process,and the deformation signals in different phases were identified by combining the GPS data with wellhead pressure data. The results show that the respiration response of surface cap rock deformation is obvious during gas injection and production of UGS,and the surface deformation due to a 1MPa change of wellhead pressure is 1. 02 mm in gas injection and 1. 24 mm in gas production horizontally, and- 1. 11 mm in gas injection and 0. 86 mm in gas production vertically.Wang Dijin Li Yu Nie Zhaosheng Wang Tan Qiao Xuejun Li Jie Yu Pengfei Cheng Ruizhong 2016Earthquake Research in China2016,30,3:0
