Tri-lateral workshop on natural hazards: towards a comprehensive assessment of risks due to natural hazards,Canada - U.S.A. - Mexico

Summary This workshop was primarily motivated by the goals of the International Decade for Natural Disaster Reduction (IDNDR), one of which is that each country should have a comprehensive national assessment of risks due to natural hazards by the year 2000. It was sponsored by the Environmental Adaptation Research Group (EARG) of Environment Canada, the International Partnerships of Environment Canada, the Geological Survey of Canada, Emergency Preparedness Canada and the Canadian National Committee of the IDNDR. The National Science Foundation of the U.S. and the Government of Mexico supported travel costs related to their delegates. The workshop dealt with both atmospheric hazards such as tornadoes and floods, and geological hazards such as earthquakes and landslides. Nine U.S., eight Mexican and 24 Canadian participants included academia, government and the private sector. Six projects were selected as being of joint interest to all three countries, with lead country and agencies identified for possible future cooperative work.

ICL Latin-American Network: on the road to landslide reduction capacity building

There is a clear need for integrated research on landslide disaster risk. Landslide disasters have major impacts in developing countries due to the increasing social vulnerability of both rural and urban communities. In recent decades, landslide disasters in Latin America triggered by both precipitation and earthquakes have also increased considerably. Thus, scientific contributions based on integrated risk research are quite urgent for improving the knowledge base for reducing the vulnerability of exposed communities to landslides. Thus, there is a parallel necessity to promote capacity building for young scientists in Latin America by considering the shift of disaster paradigm to recognize the “unnaturalness” of disasters. Under such a framework, there are particular goals to be pursued including: (1) Development of landslide regional networks with a commitment for understanding risk as a socially constructed process; (2) Engagement of young scientists in integrated landslide risk research; (3) Inducing a scientific multi- and transdisciplinary approach for integrated landslide risk research; (4) Development and implementation of capacity building; (5) Contributing to the dissemination and application of common methodologies on landslide disasters investigations; and (6) Strengthening collaboration on integrated landslide disaster risk research in Latin America. In this paper, we present one of the main activities of the ICL Latin-American network in terms of capacity building carried out in 2013; to that end, the first international workshop on forensic investigations of disasters associated with landslides was held in the University of Sciences and Arts of Chiapas in the city of Tuxtla Gutierrez, Chiapas, Mexico, from June 26th to July 4th, 2013.     

Some examples of mining in Ireland and its impact on the environment

Integral risk management: steps on the way from theory to practice

The best strategy to cope with natural hazards is the integral risk management, which involves all participants, decides on the basis of risks and also accepts a residual risk. Therefore, a substantial risk dialogue is essential not only to encourage self-responsibility. Even if throughout the Alpine perimeter this is accepted by the administration and the experts, the difficulties lie in the detail on the way to a full implementation of the effective risk management into practice. Therefore, a series of expert hearings and workshops was carried out in Bavaria to highlight the status of risk dialogue and point out the need for further development. In the beginning, an expert hearing dealt with the status of torrential risk management and worked out recommendations, focusing on the phases of reconstruction, preparation and prevention. On this basis, a practitioner workshop developed solution concepts for two case studies regarding all elements of the integral risk management. One of these was further regarded in a final workshop together with the municipality to encourage risk awareness, risk dialogue and to estimate the benefit of the measures. The activities and the results are described and summarized in the following article.     

Late-Cenozoic Magnetostratigraphy : Comparisons with Bio-, Climato-, and Lithozones

A workshop conference entitled “Late Cenozoic Magnetostratigraphy: Comparisons with Bio-, Climato-, and Lithozones” took place in Tokyo and Otsu, Japan, between October 28 and November 1, 1974. It was organized by G. J. Kukla and H. Nakagawa as an outcome of the PA-70-17 Project of the International Geological Correlation Programme, launched in 1970 by the International Union of Geological Sciences. The workshop was supported by the Japanese Society for the Promotion of Science, by IGCP, and the National Science Foundation (of the United States). Out of 70 participating geophysicists, geologists, and paleontologists, 37 attended in person, while the remaining 33 contributed by mail.¹ Prior to the conference a questionnaire was distributed in order to collect opinions on several issues. The workshop's objective was to tackle problems in the recognition of depositional polarity and to review the relationship of magneto-stratigraphic units with radiometric data and with regional bio-, litho-, and climatostratigraphic systems of the Pliocene and Pleistocene. The principal conclusions of the conference were summarized as follows:

1. (1) The only practical (though not infallible) way of demonstrating the validity of interpreted depositional polarity and magnetostratigraphic zonation is to reproduce the results in parallel, widely separated sections with different lithology and sedimentation rates.

2. (2) The hazard of unrecognized postdepositional normal overprints must be recognized and considered in all attempted correlations. Multiple sampling of parallel sections and consistency checks of magnetic data are a prerequisite for correct results.

3. (3) Continuous sequences with high sedimentation rates, such as those which originated in subsiding basins, are viewed as prospective candidates for international stratotypes of the Pliocene and Pleistocene. The investigation of such deposits should be accelerated.

4. (4) Magnetostratigraphy must follow basic stratigraphic principles. Magnetic zones should be clearly defined and locally labeled, whether or not their correlation with paleomagnetic chronology appears possible.

5. (5) Improved data on absolute age of reversals are needed. For that purpose, multiple K/Ar and fission-track analyses of key volcanic layers should be performed on a continuing basis.

     

Advances of Soil Microbiology in the Last Decade in China

Soils are fundamental to preservation and sustainability of life-support system on Earth. Soils develop as the most dynamic and complex interface linking atmosphere, hydrosphere, lithosphere and biosphere. Soils harbor enormous diversities of microbial communities as the primary driving forces for global exchanges of matter and energy on our planet. Despite of its profound importance, the invisible soil microbes have for long been underappreciated. In the early 2000s, there has been growing awareness that soil microbiology has attracted huge interest from nonsoil scientists due to the introduction of three domain phylogeny. It is also known as tree of life theory which is widely recognized as the most accurate reflection of the relatedness of all organisms and provides us with a tool to classify and elucidate the largely untapped resource of soil microbial communities. In January 2005, the Department of Earth Sciences of National Natural Science Foundation of China organized a workshop of ‘Soil Biology and Soil Processes’ with focused discussion on soil microbiology research frontiers. The workshop outlined research priorities, cross disciplinary research opportunities, technological needs and potential breakthroughs within soil microbiology. This workshop has witnessed the rapid advances of soil microbiology in soil nutrient transformation, global environmental changes and environmental remediation over the last decade in China. This article will give a brief review on soil microbial researches in the past decade in China, present the status quo of funding system and highlight the challenge and opportunities for future soil microbiology in China.

Learning to think differently: Diversity training and the ‘good encounter’

At a time of ongoing economic and social insecurity the capacity to live with difference is under renewed strain. In this context, community outreach organisations and projects of intervention that deal with diversity-related tensions are essential. This paper provides an empirical account of a diversity workshop run by an international organisation that aims to cultivate more peaceful modes of coexistence through attention to the everyday formation of prejudice. The paper has two key concerns. The first is to attend to the techniques employed to facilitate encounters with difference and to unpack the constructions of prejudiced thought. In the context of growing debates around the possibilities and challenges of coordinated contact, the paper engages with work that has articulated alternative ways of responding to difference through an attention to practices of embodied thought. The second concern focuses upon the conditions that make new ways of thinking possible and argues that in order to understand how such organisations might affect positive change, it is vital to understand how such workshops take-place. The paper therefore attends to the role of memory, habit and the working of particular affects such as shame, to open up a discussion about the ways in which workshop exercises might resonate beyond training events. The paper concludes with some reflections upon the implications for policies concerned with behavioural change in the context of developing relations across difference.     

Compaction localization in the Earth and the laboratory: state of the research and research directions

Localized compaction in porous rocks is a recently recognized phenomenon that has been shown to reduce permeability dramatically. Consequently, the phenomenon is relevant to a variety of technologies involving fluid injection or withdrawal. This article summarizes current understanding of localized compaction and impediments to further progress. The article is based on discussions at a small workshop on localized compaction sponsored by the Office of Science, U. S. Department of Energy.     

Earthlearningidea—two million and counting: bringing Earth science ideas to teachers across the world

As one door closes, another one opens—sometimes. This is certainly true in the history of the development of the Earth science education website, http://www.earthlearningidea.com . In the expectation that funding would be available to help teachers in a range of developing countries during the UN's International Year of Planet Earth in 2008, a series of overseas workshops in Earth science was proposed. Undeterred by the probable absence of funding, Chris King, of Keele University, co‐opted Elizabeth Devon and Peter Kennett to initiate a web‐based series of Earth science activities, which could be freely accessed by anyone in the world. This was, and is, run on a purely voluntary basis. Up until 2014, the website was generously hosted, free of charge, by the Applied and Environmental Geophysics Research Group at Keele University, but the site now runs on a FreeBSD server situated in the London Telehouse and managed by Martin Devon. The minimal monthly costs of this are covered by a grant from the Geologists' Association's Curry Fund.

The IUGS/IAGC Task Group on Global Geochemical Baselines

The Task Group on Global Geochemical Baselines,operating under the auspices of both the International Union of Geological Sciences(IUGS) and the International Association of Geochemistry(IAGC),has the long-term goal of establishing a global geochemical database to document the concentration and distribution of chemical elements in the Earth's surface or near-surface environment.The database and accompanying element distribution maps represent a geochemical baseline against which future human-induced or natural changes to the chemistry of the land surface may be recognized and quantified.In order to accomplish this long-term goal,the activities of the Task Group include:(1) developing partnerships with countries conducting broad-scale geochemical mapping studies;(2) providing consultation and training in the form of workshops and short courses;(3) organizing periodic international symposia to foster communication among the geochemical mapping community;(4) developing criteria for certifying those projects whose data are acceptable in a global geochemical database;(5) acting as a repository for data collected by those projects meeting the criteria for standardization;(6) preparing complete metadata for the certified projects;and(7) preparing,ultimately,a global geochemical database.This paper summarizes the history and accomplishments of the Task Group since its first predecessor project was established in 1988.     

A new high-stress undrained ring-shear apparatus and its application to the 1792 Unzen–Mayuyama megaslide in Japan

Sassa and others in the Disaster Prevention Research Institute (DPRI), Kyoto University, developed a series of undrained ring-shear apparatus to physically simulate landslide initiation and motion, from DPRI-3 (Sassa 1992) to DPRI-7 (Sassa et al., Landslides 1(1):7–19, 2004). The maximum undrained capacities in the DPRI series ranged from 300 to 650 kPa. Sassa and others in the International Consortium on Landslides (ICL) have developed a new series of undrained ring-shear apparatus (ICL-1and ICL-2) for two projects of the International Programme on Landslides (IPL-161 and IPL-175). Both projects are supported by the Science and Technology Research Partnership for Sustainable Development Program (SATREPS) of Japan. ICL-1 was developed to create a compact and transportable apparatus for practical use in Croatia; one set was donated to Croatia in 2012. ICL-2 was developed in 2012–2013 to simulate the initiation and motion of megaslides of more than 100 m in thickness. The successful undrained capacity of ICL-2 is 3 MPa. This apparatus was applied to simulate possible conditions for the initiation and motion of the 1792 Unzen–Mayuyama megaslide (volume, 3.4?×?10⁸ m³; maximum depth, 400 m) triggered by an earthquake. The megaslide and resulting tsunami killed about 15,000 people. The Unzen Restoration Office of the Ministry of Land, Infrastructure and Transport (MLIT) of Japan systematically collected various papers and reports and published two summary leaflets: one in English in 2002 and an extended version in Japanese in 2003. Samples were taken from the source area (for initiation) and the moving area (for motion). The hazard area was estimated by the integrated landslide simulation model LS-RAPID, using parameters obtained with the ICL-2 undrained ring-shear apparatus. The estimated hazard area agrees reasonably with the landslide moving area reported in the Ministry leaflets.     

Structure of the lithosphere along the deep seismic sounding profile: Tien Shan—Pamirs—Karakorum—Himalayas

During 1973–1977, as part of the International Geodynamic Project, some seismic investigations of the Earth's crust have been carried out by geotraverses of the Tien Shan—Pamirs—Karakorum—Himalayas. The seismic data obtained together with other geophysical information, allow the construction and interpretation of the lithospheric section through the Pamirs-Himalayas structure. This section includes thick crust with complex layering, supra-asthenospheric and asthenospheric layers of the upper mantle. The thickness of the Earth's crust increases from 50–55 km in the north, in the Ferghana depression (Tien Shan), to 70–75 km in the south, near the Karakul Lake (Northern Pamir). It varies within 60–65 km for the Central and Southern Pamir, Karakorum and the Inner Himalayas. Its thickness is least (35–37 km) in the south, under the outer margin of the Himalayan foredeep. Extreme gravity minima and depressions on the geoid surface correspond to the regions with maximum thickness of the Earth's crust. The centers of the disturbing masses on the geoid surface are located in the vicinity of the asthenosphere's upper layer; this determines the effect of the whole lithospheric layer, including its asthenospheric layer, at intense changes of gravity anomalies. The asthenospheric upper layer is recorded at a depth of about 120 km, its base at a depth of 200 km, in the northern and southern regions, and 300 km in its central part (Southern Pamir, Karakorum). In the middle asthenospheric layer, wave velocities decrease to 7.5 km/sec, under the base they increase to 8.4 km/sec and reach 9.4 km/sec at a depth of about 400 km. In the supra-asthenospheric layer of the upper mantle, longitudinal and shear wave-velocities slightly increase (by less than 0.1 km/sec) towards its base.     

某工厂夜光车间环境放射性监测、评价及防护

在黑暗环境中显示仪表指示常采用荧光技术。某工厂夜光车间是利用掺人放射性物质的荧光粉对玻璃制品进行涂抹、描绘等工艺加工的生产车间。由于荧光粉中掺人放射性物质^226Ra、^40K,^226Ra、^40K在自发衰变过程中会放出α、β、γ射线,对人体会产生不同程度的损伤,大剂量或累计照射会对人类造成一定辐射影响。因此,工作时应严防人为等意外因素可能造成超安全计量的放射性损害。为确保夜光车间工作人员和公众人身健康与安全,必须定期对夜光车间及周围环境进行放射性监测与评价。通过环境放射性监测．分析环境辐射水平,寻找可能存在的问题,进而提出保障人体健康的防护措施。
