Intraplate Earthquakes in North China
5 Intraplate earthquakes in North China mian liu, hui wang, jiyang ye, and cheng jia Abstract North China, or geologically the North China Block (NCB), is one of the most active intracontinental seismic regions in the world. More than 100 large (M > 6) earthquakes have occurred here since 23 BC, including the 1556 Huax- ian earthquake (M 8.3), the deadliest one in human history with a death toll of 830,000, and the 1976 Tangshan earthquake (M 7.8) which killed 250,000 people. The cause of active crustal deformation and earthquakes in North China remains uncertain. The NCB is part of the Archean Sino-Korean craton; ther- mal rejuvenation of the craton during the Mesozoic and early Cenozoic caused widespread extension and volcanism in the eastern part of the NCB. Today, this region is characterized by a thin lithosphere, low seismic velocity in the upper mantle, and a low and flat topography. The western part of the NCB consists of the Ordos Plateau, a relic of the craton with a thick lithosphere and little inter- nal deformation and seismicity, and the surrounding rift zones of concentrated earthquakes. The spatial pattern of the present-day crustal strain rates based on GPS data is comparable to that of the total seismic moment release over the past 2,000 years, but the comparison breaks down when using shorter time windows for seismic moment release. The Chinese catalog shows long-distance roaming of large earthquakes between widespread fault systems, such that no M ࣙ 7.0 events ruptured twice on the same fault segment during the past 2,000 years. -

Li et al. BMC Psychiatry (2020) 20:78 https://doi.org/10.1186/s12888-020-2474-z RESEARCH ARTICLE Open Access Prevalence and risk factors of post- traumatic stress disorder among elderly survivors six months after the 2008 Wenchuan earthquake in China Lan Li1,2,3, Jan D. Reinhardt3,4,5, Craig Van Dyke1,6, Heng Wang7, Maoqiong Liu8, Aiko Yamamoto9, Qian Chen10* and Xiuying Hu11* Abstract Background: Several studies indicate that older age is a risk factor for probable post-traumatic stress disorder (PTSD). However, evidence on the prevalence and risk factors for elderly disaster survivors is limited. Methods: Multi-stage stratified sampling was applied in this cross-sectional study. The Revised Version of the Impact of Event Scale (IES-R) was used to evaluate symptoms of PTSD. Chi-squared test was used for univariable analysis of prevalence of probable PTSD by possible determinants. Multivariable logistic regression analysis was utilized to further explore risk factors for PTSD. Results: 427 elderly survivors age 60 or older participated. The prevalence of probable PTSD was 40.5, 36.3, and 21.5% according to a cut off score of the IES-R of 33, 35, and 2 points on average across items, respectively. In multivariable logistic regression, elderly survivors with a higher number of diagnosed chronic illnesses were more likely to be screened positive for PTSD and those with a greater number of family members living in the same home were less likely to be classified as having probable PTSD for all cut off scores. Elderly survivors with improved economic status and those with primary school or lower education were more often estimated to have probable PTSD with a cut off score of 35 and 2 points on average. -

Lessons Learnt from the 512 Wenchuan Earthquake: Perception of Seismic Risks
Australian Earthquake Engineering Society Conference AEES 2008, Ballarat, Victoria. Special Session on 512 Wenchuan Earthquake Lessons Learnt from the 512 Wenchuan Earthquake: Perception of Seismic Risks Hing-Ho Tsang Research Fellow, Department of Civil Engineering, The University of Hong Kong, Pokfulam Road, Hong Kong, China. Email: [email protected] Abstract On May 12, 2008, a devastating earthquake occurred in Sichuan Province of China depriving tens of thousands of lives and destroying homes of millions of people. In this article, the seismotectonic background and the seismicity of the regions are first introduced. The seismic hazard levels specified in the Chinese Code for Seismic Design of Buildings, GB 50011 – 2001, and issues concerning the perception of earthquake risks and the extensive damage to buildings in the affected regions are discussed. Keywords: Wenchuan Earthquake, Sichuan, China, seismic, hazard, risk, intensity 1. BRIEF BACKGROUND OF THE 512 WENCHUAN EARTHQUAKE At 06:28:01.42 UTC on May 12, 2008, a devastating earthquake occurred at the Wenchuan County in the Sichuan Province of China. On the moment magnitude scale, the earthquake was of Mw = 7.9 according to reports from the United States Geological Survey (USGS). On the surface wave magnitude scale, the earthquake was of Ms = 8.0 according to reports from the China Earthquake Administration (CEA). The epicentre of the earthquake was 80 km west-northwest of the provincial capital city of Chengdu (refer Figure 1(a)). The fault ruptured at a depth of about 19 km. There were over 200 aftershocks with magnitudes greater than 4.0 and 8 aftershocks with magnitude greater than 6.0 occurred in the area afterwards. -

Appendix A A Study of the Haicheng Foreshock Sequence By Lucile Jones, Wang Biquan and Xu Shaoxie (English Translation of a Paper Published in Di Zhen Xue Bao (Journal of Seismology), 1980.) Abstract We have examined the locations and radiation patterns of the foreshocks to the 4 February 1978 Haicheng earthquake. Using four stations, the foreshocks were located relative to a master event. They occurred very close together, no more than 6 kilo meters apart. Nevertheless, there appear to have been too clusters of foreshock activity. The majority of events seem to have occurred in a cluster to the east of the master event along a NNE-SSW trend. Moreover, all eight foreshocks that we could locate and with a magnitude greater than 3.0 occurred in this group. The're also "appears to be a second cluster of foresfiocks located to the northwest of the first. Thus it seems possible that the majority of foreshocks did not occur on the rupture plane of the mainshock, which trends WNW, but on another plane nearly perpendicualr to the mainshock. -
History of Badminton
Facts and Records History of Badminton In 1873, the Duke of Beaufort held a lawn party at his country house in the village of Badminton, Gloucestershire. A game of Poona was played on that day and became popular among British society’s elite. The new party sport became known as “the Badminton game”. In 1877, the Bath Badminton Club was formed and developed the first official set of rules. The Badminton Association was formed at a meeting in Southsea on 13th September 1893. It was the first National Association in the world and framed the rules for the Association and for the game. The popularity of the sport increased rapidly with 300 clubs being introduced by the 1920’s. Rising to 9,000 shortly after World War Π. The International Badminton Federation (IBF) was formed in 1934 with nine founding members: England, Ireland, Scotland, Wales, Denmark, Holland, Canada, New Zealand and France and as a consequence the Badminton Association became the Badminton Association of England. From nine founding members, the IBF, now called the Badminton World Federation (BWF), has over 160 member countries. The future of Badminton looks bright. Badminton was officially granted Olympic status in the 1992 Barcelona Games. Indonesia was the dominant force in that first Olympic tournament, winning two golds, a silver and a bronze; the country’s first Olympic medals in its history. More than 1.1 billion people watched the 1992 Olympic Badminton competition on television. Eight years later, and more than a century after introducing Badminton to the world, Britain claimed their first medal in the Olympics when Simon Archer and Jo Goode achieved Mixed Doubles Bronze in Sydney. -

Study on Urban Efficiency Measurement and Spatiotemporal
sustainability Article Study on Urban Efficiency Measurement and Spatiotemporal Evolution of Cities in Northwest China Based on the DEA–Malmquist Model Jun Yin and Qingmei Tan * College of Economics and Management, Nanjing University of Aeronautics and Astronautics, Nanjing 211106, China; [email protected] * Correspondence: [email protected] Received: 18 November 2018; Accepted: 12 January 2019; Published: 15 January 2019 Abstract: Urban efficiency can effectively measure the management and allocation level of urban factor inputs. Based on the data of 30 prefecture-level cities in Northwest China from 2006 to 2015, urban efficiency is measured by data envelopment analysis (DEA). Then the spatiotemporal evolution rule is identified by Malmquist model. The results illustrate that the overall average urban efficiency of cities in Northwest China each year from 2006 to 2015 was at the low level. Only Jiayuguan, Yulin, Yan’an, and Karamay reached the high average urban efficiency, while Dingxi, Pingliang, Guyuan, Shangluo, Tianshui, Longnan, and Baiyin were at the inefficient level. Most cities in Northwest China were still in the “growing” stage of increasing returns to scale. The scale of urban investment was relatively insufficient, and economies of scale had not yet formed. Cities with decreasing returns to scale were mainly distributed in the capital cities and the central and sub-central cities of Guanzhong-Tianshui Economic Zone with relatively abundant urban resources and capital. Cities with constant returns to scale were mainly distributed in four cities including Yan’an, Yulin, Jiayuguan, and Karamay with high efficiency. The overall comprehensive efficiency, technical efficiency, and scale efficiency of cities in Northwest China were not only low, but also showing a downward trend. -
Distribution Pattern of Landslides Triggered by the 2014

This paper presents a preliminary analysis of the distribution patterns and characteristics of these co-seismic landslides. In total, 1826 landslides with a total area of 19.12 km2 triggered by the 3 August 2014 Ludian earthquake were visually interpreted using high-resolution aerial photos and Landsat-8 images. The sizes of the landslides were, in general, much smaller than those triggered by the 2008 Wenchuan earthquake. The main types of landslides were rock falls and shallow, disrupted landslides from steep slopes. These landslides were unevenly distributed within the study area and concentrated within an elliptical area with a 25-km NW–SE striking long axis and a 15-km NW–SE striking short axis. Three indexes including landslides number (LN), landslide area ratio (LAR), and landslide density (LD) were employed to analyze the relation between the landslide distribution and several factors, including lithology, elevation, slope, aspect, distance to epicenter and distance to the active fault.
