  • S1-1-1 Crustal and upper mantle and seismogenic structure of the Wenchunan earthquake
  • Convenor Jianping WU (China), Fuyun WANG (China), Zhifeng DING (China), Fenglin NIU (USA)
  • Introduction:
    The Wenchuan Ms 8.0 earthquake occurred in the eastern boundary zone of the Tibetan Plateau. The area experienced a complicated geological and tectonic evolution history, leading to the development of a complex crustal and mantle structure beneath the area. Understanding where and how intra-plate large earthquakes occur is a major focus of earthquake science. We invite contributions on any aspect related to the imaging of seismogenic structure of the Wenchuan earthquake. Studies focus on the crustal and upper mantle structures, the deep geometry of Longmenshan fault system, the influence of fluids on earthquakes, high-precision spatial distribution of seismicity before and after the main earthquake are particularly encouraged. We also welcome presentations on regional studies of viscosity, anisotropy, density and geodynamics in the eastern margin of the Tibetan Plateau. Topics like the seismogenic structure of other major earthquakes will be gladly received.
 
  • S1-1-2 Subsurface imaging and monitoring with ambient seismic noise
  • Convenor Huajian YAO (China), Lihua FANG(China), Yingjie YANG (Australia)
  • Introduction:
    Cross-correlation of continuous ambient noise field can yield Empirical Green’s functions between receiver pairs. It has been demonstrated that not only broadband surface waves can be recovered and used to image 3-D subsurface structures (velocity and attenuation) from local to global scales, but also certain phases of body waves can be successfully retrieved to image both smooth and interface structures of the Earth. Another important application of ambient noise cross-correlation is to monitor temporal variations of velocity structures, which plays a key role in monitoring dynamic processes of the Earth’s interior, e.g., volcanic and earthquake processes. In particular, with more and more dense-array deployments nowadays, we have unprecedented opportunities to achieve very high-resolution images of subsurface structures in both spatial and temporal scales. In this session, we welcome contributions using ambient noise cross-correlation methods to better understand the structure and its temporal changes in the regions of the 2008 Wenchuan earthquake. We also welcome novel developments of ambient noise data processing and imaging methods. Applications of ambient noise methods in other regions are also welcome. 
 
  • S1-1-3 Advances in active source monitoring
  • Convenor Hongti WANG (China), Baoshan WNAG (China), Hongfeng YANG (Hong Kong, China)
  • Introduction:
    The earth’s structure changes at spatiotemporal scales, studying the temporal variation of the subsurface are of key importance in understanding the dynamic earth’s process and mechanism of hazardous event as earthquakes. Recently, a variety of passive and active source methods are being developed to investigate the temporal changes at various scales. Here we invite abstracts related to recent advances in subsurface monitoring with both passive- and active-source. Topics may include, but are not limited to, development of environmental-friendly active sources, method in related data processing, results from temporal change monitoring.

  • S1-2-1 Uplift history and deformation mechanism of the Tibetan Plateau
  • Convenor Jing LIU (China), Peizhen ZHANG (China), Xiwei XU (China), Erqi WNAG (China), Chengshan WANG (China)
  • Introduction:
    Understanding the spatial and temporal pattern of surface uplift and lithospheric deformation of the Tibetan plateau is fundamental for exploring the geodynamic driver for building high plateaus, and Cenozoic changes in Asian climate, and surface processes shaping the spectacular plateau landscape. In addition, the Tibetan plateau and its neighboring regions are among the most tectonically active regions in the word, and several destructive earthquakes occurring over the past several decades demand a better understanding of active tectonic processes over various temporal and spatial scales to estimate seismic hazards. Recent multidisciplinary studies, including geophysics, structural geology, sedimentology and stratigraphy, geochemical/geochronological/paleo-altimetry, tectonic geomorphology, paleo-seismology, geodesy, and numerical/analogue modeling, have offered quite a lot new observations to understanding the uplift history and deformation mechanisms of the Tibetan plateau and its neighboring regions. In this section, we seek contributions from scientists who work on all aspects, and encourage submissions working on (1) examining the distribution of deformation over a variety of spatial and temporal scales, from individual faults over short/intermediate-timescales to the entire fault system over Myrs time scale; (2) detecting the magmatic, sedimentary, and metamorphic records for crustal thickening and exhumation during the plateau growth; (3) reconstructing the topographic evolution of the plateau landscape, including past absolute elevation and spatiotemporal pattern of erosion rates; (5) numerical modeling regarding the plateau growth and the corresponding kinematic and geodynamic processes, landscape evolution driven by the interaction of tectonic and climatic forcing, and stress loading among the active fault systems and earthquake rupture. Submissions focusing on the plateau uplift and deformation mechanisms beyond the Tibetan plateau are also welcome as well.
 
  • S1-2-2  Interseismic strain accumulation and earthquake cycle
  • Convenor Guojie MENG (China), Shuanggen JIN (China), Hiroaki TAKHASHI (Japan), Shestakov NIKOLAI (Russia)
  • Introduction
    Understanding and characterizing the seismic strain accumulation and earthquake cycle processes are extremely important for earthquake forecast and seismic hazard mitigation. Significant progress has been achieved during the past decades in this field, thanks to unprecedented coverage of geodetic and seismic networks, as well as novel modeling techniques. Integration and analysis of different time-scale geological, geophysical, seismological and geodetic observations formed an almost complete view of earthquake cycle. To promote interdisciplinary studies which deal with strain accumulation and earthquake cycle processes, this session will bring together scientists working on paleoseismic, geodetic, geophysical, geomorphic and seismologic datasets to provide a comprehensive understanding of the earthquake cycle. Abstracts from multiple perspectives are encouraged based on the following topics, but not limited to: (1) Field and/or laboratory investigation of earthquake deformation process; (2) Observation and modeling of strain accumulation and earthquake cycle; (3) Investigation of fault structure and physical conditions where strain accumulations is observed; (4) Strain accumulations and its relationship with large earthquakes of different mechanisms and seismic hazard; (5) Relationship between the earthquake cycle and regional tectonics; (6) Improving of observational and processing methods used for the investigation of interseismic strain accumulation and earthquake cycle.
 
  • S1-2-3  Active fault, paleoearthquake, tectonic geomorphology, and surface processes
  • Convenor Honglin HE (China), Youli LI (CHina), Jie CHEN (China), Huiping ZHANG (China), Shenghua LI (China), Lewis OWEN (USA), Yasutaka IKEDA (Japan)
  • Introduction
    Seismic risk evaluation is mainly based on the seismic record, including both historical and instrumental earthquakes. The accuracy of the seismic risk evaluation then mainly relies on the integrity of seismic records, usually a record longer than one seismic cycle is necessary. Therefore, how to prolong the seismic record to more than one seismic cycle is very important to make an accurate seismic risk evaluation. Paleoseismology, a very useful method to prolong seismic record, is the study which aims to identify paleoearthquake preserved in these disrupted stratigraphic units and displaced landforms through paleo-seismological trenching and geomorphological analyses. The geomorphic features (mainly displaced linear or planar landforms) generated by surface ruptures and surface processes provides valuable information on how an earthquake along a given fault is characterized and whether those characteristics recur in prior earthquakes. Tectonic geomorphology form and evolve due to the alternation of co-seismic slip along fault and erosional processes operating on the topographic surface. It thus reflects not only on the repeating occurrence of slip along a fault but also on the degradational surface processes that modify its original shape. To properly constrain an earthquake’s along-fault slip distribution and subsequently a fault’ slip accumulation patterns from displaced geomorphic marks, the initial marker morphology needs to be inferred with confidence and a sound understanding of geomorphic response to prevailing climatic conditions, which alters this initial morphology, is required.
    In this session, we welcome contributions describing and critically discussing new ideas and different approaches to study paleoearthquake, tectonic geomorphology, and surface processes. We are particularly interested in studies applying new and innovative methodological or multidisciplinary approaches. We hope to assemble a broad program bringing together studies applying a variety of methods such as paleoseismic trenching, high-resolution coring, geophysical imaging, remote sensing, traditional tectonic geomorphology and digital tectonic geomorphology, as well as the application of earthquake geology and statistics in seismic hazard assessments. In addition, we encourage contributors illustrating and exploring the advances in dating paleoseismology, active tectonics, and surface processes.
 
  • S1-2-4 Wenchuan earthquake sequence: a comprehensive understanding of its tectonic origin, physical processes, and hazard implications
  •  (United with S5-1-4)
  • Convenor Zhengkang SHEN (USA), Xiwei XU (China), Xiaofeng CUI (China)
  • Introduction
    Earthquake is the complex result under the mutual impact of multi-factors, which may involve issues of geodynamics, geochemistry, and other ambits. However, it is essentially the mechanical-instability and rupture of the rock. As the mechanical environment, the tectonic stress plays crucial role during the seismogenic and occurrence process of earthquake. This section focuses on the recent research on tectonic stress fields related to strong earthquakes, includes the development of in-situ stress measurement method and its implementation, the tectonic stress filed backgrounds for strong earthquakes, the stress accumulation during the seismogenic process, the dynamic change of stress field during the occurrence, the stress filed variations induced by strong earthquakes, as well as the multi-aspect influence from the tectonic stress changes. Contributions are not limited to Wenchuan earthquake, and the related researches for other strong earthquakes are also welcome.

  • S2-1-1 Retrospect and calibration of observations for Wenchuan Earthquake: potential precursors and co-seismic responses
  • (United with S2-4-4)
  • Convenor Qinghua HUANG (China), Xuemin ZHANG (China), Bin CHEN (China), Jann-Yeng LIU (Taiwan, China), Sergey PULINETS (Russia)
  • Introduction:
    Wenchuan earthquake brought disastrous consequence in China, and it also challenges the existed seismic monitoring and prediction system. This earthquake is quite special, neither obvious pre-seismic activities, nor lots of precursory phenomena that were submitted before it, which showed big differences with others such as Tangshan Ms7.6 earthquake in 1976, Haicheng Ms7.3 earthquake in 1975, etc. So retrospect and introspection are quite important to help us find out the problems and try to improve or solve them in future when we face the similar situation. This session mainly focus on the researches correlated to Wenchuan Ms8.0 earthquake on May 12 2008, including the further investigations and verification on precursors that have been found, the potential precursory signals by using new technology, new data, or new methods, the co-seismic responses, and even the observations during the aftershocks of Wenchuan earthquake. It is welcome for all the presentations to help understanding the preparation, occurrence and propagation processes and their mechanisms for Wenchuan earthquake. Solicited contributions include observational, analytical, theoretical and numerical simulation papers.

  • Introduction
 
  • S2-2-2   Earthquake physics: simulation and observations
  • Co-organized by APEC Cooperation for Earthquake Simulation (ACES)
  • Convenor Huilin XING (Australia), Yongxian ZHANG(China), Shiyong ZHOU (China)
  • Introduction:
    Earthquakes are amongst the most costly and deadly of all natural phenomena. An overwhelming majority of the world’s earthquakes strike APEC member economies located around the Pacific Rim. Earthquake generation is controlled by a vast range of physical processes occurring over many orders of magnitude of scale in space and time. At the smallest scales, these processes include microscopic frictional interactions within fault zones and rock fracture. Motions of tectonic plates and mantle convection are important at the largest scales. Much remains unknown about the earthquake generation process, hampering earthquake mitigation and forecasting efforts. Recent developments in laboratory experiments, field observations and numerical simulations offer the possibility for an improved understanding of earthquake physics towards earthquake predictions.
 
  • S2-2-3   Anthropogenic seismicity: induced and triggered earthquakes
  • Co-organized by Asian Seismological Commission (ASC)
  • Convenor Harsh K. GUPTA (India), Yaolin SHI (China), Yong CHEN (China)
  • Introduction:
    Under suitable geological situations, some of the anthropogenic activities such as creation of the artificial water reservoirs, underground coal and metal mining, oil extraction, geothermal energy production etc. can trigger/induce earthquakes. There is a very fine distinction between the induced and triggered earthquakes. When the causative activity accounts for a substantial part of the stress change, the resultant earthquake is termed as induced, while in the case of triggered - earthquakes, the stress changes associated with causative activity are very small. Reservoir triggered seismicity (RTS) has been observed at over 120 sites globally and damaging earthquakes exceeding magnitude 6 have occurred at 4 places. The largest induced earthquakes have exceeded magnitude 5 in gold mines of South Africa and India. The socio-economic impact of induced/triggered earthquakes is immense. A proper understanding of the factors and situations conducive to such earthquakes is very important. The aim of this session is to invite contributions to elucidate the genesis of such events, case histories and way forward to make creation of artificial water reservoirs, mining and production of natural resources safer.

  • S2-3-2   Advances in geodetic study of devastating earthquakes
  • Convenor Wenke SUN (China), Qi WANG (China), Rongjiang WANG (Germany), Peiliang XU (Japan)
  • Introduction:
    odern geodetic techniques, including GNSS, SLR, VLBI, DORIS, InSAR, Satellite Altimetry and Satellite Gravimetry, are capable of measuring and monitoring small changes of Earth’s surface and interior mass transportation with high accuracy and spatial-temporal resolution. Particularly increasingly dense GNSS and other geodetic observation networks provide a unique opportunity to investigate crustal deformation and its mechanism of great devastating earthquakes, such as the great 2008 Wenchuan earthquake. The great Wenchuan earthquake has a unique rupturing process, complex fault geometry, geodynamics and data interpretation for pre-, co-, and post-seismic deformations. Just 10 years after the Wenchuan earthquake, it is worthwhile to review the advances in geodetic study of this earthquake. Any topics related to other devastating earthquakes are also welcome.
 
  • S2-3-4   Development of geophysical field detecting satellite mission
  • Convenor Xuhui SHEN (China), Fan JIANG (China), Piergiorgio PICOZZA (Italy), Rune FLOBERGHAGEN (Italy)
  • Introduction:
    Geophysical fields include the geomagnetism field, geo-gravity field and electro-magnetic field, which take the role of the link-bridge among the lithosphere, atmosphere, ionosphere, and magnetosphere to understand the interacting and coupling mechanisms each other . Following the developing of space science and technology, the detection of geophysical fields based on satellites has been going on, for examples, MAGSAT, ORSTED, DEMETER, SWARM, GOCE, CHAMP, GRACE and so on. The latest one is the China Seismo-Electromagnetic Satellite, named ZH-1 launched on February 2, 2018. ZH-1 is the first space-born platform of the China earthquake observation system and the first satellite of the China geophysical fields detection mission. This session will focus on the following issues: inter-calibration for the space-based geophysical data, data procession methodologies and data application, the payloads and satellite platform developing, as well as the future proposals and missions.
 
  • S2-3-5   Earthquake physics and lithosphere-coversphere-atmosphere-ionosphere coupling: clues from Global Earth Observation System of Systems (GEOSS)
  • Convenor Lixin WU (China), Angelo De SANTIS (Italy), Rita Di GIOVAMBATTISTA (Italy)
  • Introduction:
    The scientific interpretation and systematic understanding of earthquake physics and Lithosphere-coversphere-atmosphere-ionosphere (LCAI) coupling process are the scientific foundation of analyzing to abnormal earth system behaviors and appearancesas particular responses to seismic activity. The spaceborne, airborne, and ground-based platforms as well as the multi- parameter observations are providing new opportunity and challenge to seismic process, earthquake physics and LCAI coupling. The terrible Ms7.9 Wenchuan earthquake, May 12, 2008, in China and other medium-strong earthquakes happened during the last decades in the world had accompanied with a large amount of investigations and studies on above mentioned issues. More deep and detailed researches and investigations on the synergic observation and integrated interpretation on earthquake physics and earthquake related LCAI coupling are very necessary. Systematic retrospect, statistical analysis, mechanism exploration and case studies are all valuable to solid the foundation of earthquake physics and LCAI coupling, and to facilitate the development of earthquake anomaly identification, recognition, and with multiple observations supported with GEOSS. Contributions not limited to the following topics are welcome:
    1) Earthquake physics and earth system response
    2) LCAI coupling appearance related with seismic activity
    3) Earthquake anomaly identification and recognition
    4) Multi-parameter analysis and validation
    5) Statistic and case study
 
  • S2-3-6   Global seismo-geodetic observation: GPS, strain accumulation and silent earthquakes

  • Convenor Paramesh BANERJEE (Singapore), Sidao NI (China), Jianghui GENG (China), Han YUE (China), Qiming ZENG (China), Jingfa ZHANG (China)
  • Introduction:
    With the advent of modern space based geodetic technology and advancement of seismological instrumentation, the line between Seismology and Geodesy are fading away steadily. The solid earth deformation, both elastic and visco-elastic, spans a large temporal (and spatial) scale, from millions of years of tectonic motion to tens-of-Hz of seismic shaking. Modern seismo-geodetic observations using seismological sensors, gravity meter and GNSS stations, together, provide ameasurement systemthat spans a very wide frequency spectrum of the elastic response originated fromthe surface and sub-surface processes. This leads to possibility of more detailed understanding of the complicated driving stress and deformation mechanisms inside the crust and mantle.
    This session invites contributions from seismo-geodetic studies of geological fault motion, strain accumulation through different phases earthquake cycle (inter-seismic, co-seismic and post-seismic) and related fields, with emphasis on following topics, but not exclusive to:
    1. Regional strain field leading to tectonic and seismic motions.
    2. Regional and local scale plate/block motion with emphasis on localization of strain accumulation, or lack of it, leading to estimate of seismic hazard assessment.
    3. Strain accumulation and release through inter-seismic and post-seismicphases of earthquake-cycle and/or their relationship with co-seismic energy release and kinematic processes.
    4. Source processes of slow earthquakes, silent earthquakes or other anomalous earthquakes.
    5. Seismo-geodetic observation and studies of other deformation processes, such as landslide, glacier-quake, etc.
    6. Societal aspects of Seismo-geodetic observation system and instrumentation network.
    7. Status of seismo-geodetic observation system in Asian countries in particular, and global in general.

  • S2-4-1  Earthquake natural laboratory and large earthquake forecasting
  • Co-organized by South California Earthquake Center (SCEC), National Test Site for Earthquake Monitoring and Forecast
  • Convenor Gregory C. BEROZA (USA), Jinwei REN (China), Zhengkang SHEN (USA), Xiaodong ZHANG (China)
  • Introduction:
    Since the 1960s, many countries and regions in the world have studied earthquake prediction in seismological field experiments, or natural laboratories. By making intensive observations, these efforts have led to a deeper scientific understanding of the earthquake preparation process and of earthquake occurrence. These observations and experiments in natural laboratories have led to new insights, but have also highlighted aspects of earthquake behavior that we do not yet understand. At the end of 2014, to steadily promote progress in the science and technology of seismic monitoring and prediction in the country, China Earth Administration decided to set up National Earthquake Monitoring & Prediction Experimental Field in Sichuan & Yunnan. By establishing the shared service platform for the Experimental Field, it will gradually secure the sharing of seismic data, attract high-level internal and external seismic research efforts, and promote major seismic studies, including: application of new technologies for earthquake monitoring, pioneering of new approaches for earthquake forecasting, and the development of dynamic models in the Experimental Field, etc. 
    This session, jointly sponsored by Southern California Earthquake Center andNational Earthquake Monitoring & Prediction Experimental Field in Sichuan & Yunnan, sincerely invites Chinese and overseas scholars, who come from the fields of geology, geophysics, geodesy, and seismology, to contribute their perspectives and insights on the science of earthquakes. At the same time, we encourage exchanges of research results that help enlighten and promote the seismological studies and forecasting of damaging future earthquakes in all settings.
 
  • S2-4-2   Improving earthquake occurrence and hazard forecasts
  • Co-organized by APEC Cooperation for Earthquake Simulation (ACES)
  • Convenor John B. RUNDLE (USA), Huilin XING (Australia), Yongxian ZHANG (China)
  • Introduction
    Earthquake occurrence, hazard forecasts (hazard maps) and nowcasts have long lagged behind similar applications, such as weather, economic, or population forecasts and nowcasts, especially in addressing issues of verification and validation. Validation asks how well the algorithm used to produce the forecast implements the conceptual model (have we built the model right?). Verification asks how well the model forecasts the observations that actually occur (have we built the right model?). In recent years, this situation has been changing, in part via adopting ideas from other forecasting applications. We invite papers dealing with issues such as defining forecast and nowcast goals, improving models with new data or methodology, testing against observations, assessing uncertainties, and better using forecasts and nowcasts for hazard mitigation. Forecasts and nowcasts can be achieved either using sophisticated models of fault interactions, or by analysis of online catalogs. We invite papers that address any or all of these issues.
 
  • S2-4-3   Multi-parameters observations of pre-earthquake signals and their potential for prediction
  • Convenor Dimitar OUZOUNOV (USA), Xuhui SHEN (China), Fuqiong HUANG (China), Katsumi HATTORI (Japan)
  • Introduction:
    Year of 2018 is the10th year of remembering the 2008 Wenchuan Earthquake disaster in China that is part of the recent catastrophic earthquakes (the 2004 Sumatra, the 2011 Tohoku, Japan, the 2015 in Nepal) claimed thousands of lives and caused extensive economic losses. Still the International science community is looking for solutions in the early detection of major seismic events in order to minimize the loss of human life. Multiple detections of earthquake precursory signals have been reported before the 2008 Wenchuan earthquake quake and before major events worldwide, and the new observations from space and ground have provided new evidences about the existence of pre-earthquake processes. In this session, while still discussing the applicability of pre-earthquake signals towards short-term earthquake forecasting, we expect to see the latest progress in short –term earthquake forecasting and the integration of multi-parameter observations.

  • S2-5-3  Application of artificial intelligence techniques in earthquake studies
  • Convenor Jieyuan NING (China), Lihua FANG (China), Zhigang PENG (USA)
  • Introduction
    Earthquake prediction, especially short-term prediction, is a worldwide unsolved problem. The challenges are mainly come from lack of both long-term recordings of geophysical data and detailed knowledge of Earth structures, which render earthquake statistics and geodynamic modeling ineffective. Nowadays, however, there are dramatic increases in the quantity and quality of geophysical data. These data partly alleviate the difficulty in long-term data shortage, providing much better opportunity on determining Earth’s fine structure and revealing the mechanisms of earthquake nucleation, propagation and termination. Meanwhile, advances in data science, especially artificial intelligence, dramatically increase the accuracy and efficiency of data analysis. They provide new approaches for solving problems from different perspectives, enabling automatic characterization of various types of signals, data compression, noise reduction, seismic phase identification and event detection, seismic source characterization, inference of the Earth’s fine structure, and novel visualization. With the abundant geophysical data as well as advances in computer and information technologies, there are great opportunities for data science to extract meaningful insights for inverting the Earth’s structures, understanding earthquake dynamics, and mitigating earthquake hazards. In this session we seek new thoughts, methods and technologies that will contribute to new way of data acquisition, the efficient and safe storage, processing and transmitting of big data, properly presenting computational results, automatic detection of seismic phases, extraction of earthquake signals, accurate inversion of the Earth’s structure, effective recognition of earthquake precursors, identification of earthquake nucleation, propagation and termination processes, etc.

  • S3-1-5 Landscape response to earthquakes and resulting secondary hazards
  • Convenor A. Joshua WEST (USA), Zhangdong JIN (China), Chong XU (China)
  • Introduction:
    The striking immediate damage from large continental earthquakes attracts justified attention, but the longer-term effects of these events on the natural landscape are also of fundamental importance. The Wenchuan earthquake particularly highlighted the central role of earthquake-triggered landslides as a hazard and as an erosional agent. These landslides inflicted immediate damage and were also the beginning of a series of “cascading hazards” that included debris flows and floods that occurred in the years following 2008. Ten years after the earthquake, we can look back and reflect on how these follow-on hazards prolonged the damage from the earthquake and hampered reconstruction — and how lessons from the sequence following the Wenchuan earthquake may guide understanding of similar events in the future.At the larger scale, the Wenchuan case provided greater understanding of how earthquake-triggered landslides contribute to erosional fluxes, thus shaping the geodynamics of tectonically active landscapes and potentially contributing to feedbacks between seismicity, erosion, and landscape evolution. Whether and how repeated large earthquakes may have contributed to the topography of eastern Tibet remains an open question. This session will bring together research from the Wenchuan earthquake as well as other large continental earthquakes aimed at understanding the landscape response to these events, considering both the hazard and tectonic perspectives.
  • S3-1-6 Seismic hazard assessment
  • (United with S3-3-3)
  • Co-organized by Asian Seismological Commission (ASC)
  • Convenor ChunXiang CAO (China), Ruben TATEVOSSIAN(Russia), Toshiaki YOKOI (Japan), Ramesh P. SINGH (USA)
  • Introduction:
    The seismic hazard assessment is multistage complex procedure including seismic observations at dense local network, elaboration of seismotectonic models, selection and justification of ground motion prediction equations, building of hazard curves and design response spectra, site response analysis, and generation of accelerograms. Very important issue, of crucial importance for critical facilities, such as nuclear power plants (NPP), is adequate level of conservatism. This issue is difficult to formalize, normally it is evaluated on the base of expert judgment. But the problem is still rather unclear. Contributions related to any of the topic incorporated in the seismic hazard assessment are welcomed. Discussions on the balance between formal procedures and expert judgment approach in hazard assessment are appreciated. In view of intensive design and construction works of critical facilities in Asia, such as NPPs in China, India, Bangladesh, Philippines, Vietnam, etc., it is encouraged to discuss seismic hazard assessment with emphasis to critical facilities. The potential papers can presents both methodological approaches and practical applications of well-known techniques.

    Science and technology is the root of informed decision-making in disaster risk reduction (DRR). Roles of science and technology has got enhanced attention in the Sendai Framework for DRR and there has been prominent global and several regional initiatives to enhance multi-stakeholder partnership in implementing science-based decision-making.

Meanwhile, communities are the first responders in case of a disaster. Therefore, community-based disaster risk reduction (CBDRR) should be the core of any risk reduction approach. The CBDRR need to build on people's local knowledge and cultural practices, and apply technological tools and approaches that people can easily understand and integrate into their lives.This session will present interactive practice among multiple stakeholders, and welcomes innovative papers on the following topics: innovative technology, App development, system building, social training, CBDRR activities, and science education.

  • Convenor Mengtan GAO (China), Marco PAGANI (GEM)
  • Introduction
    GEM (Global Earthquake Model) Foundation is motivated to serve the public good in a collaborative, credible, open and transparent manner. It strives to make seismic risk assessment inclusive to create a holistic culture of awareness and resilience, bringing a once-scarce resource available to all sectors and beneficiaries. It works from research to practice, from knowledge to action, the GEM’s efforts are ultimately motivated by the welfare of the public. It collaborates across sectors, geographies and disciplines to promote knowledge and information sharing in an open, transparent manner. It is able to bring together diverse stakeholders from scientific community to policy makers, from global to local partners to deliver impact on the ground because of our professional track record in global seismic hazard and risk assessment. the GEM’s products, data and processes are transparent and freely accessible to the public. GEM strives to develop trustworthy hazard and risk evaluations, vital for organizing rescue and humanitarian activities when an earthquake occurs. GEM works to ensure that damage and loss assessments before and after an earthquake are accurate in order for governments to respond quickly in areas where assistance is most needed, and in order for communities to ‘build back better’. In recent years, GEM is organizing the project of global seismic hazard and risk assessment and the global seismic hazard map will be completed in 2018. In this session, we plan to show the services, tools, products and achievements GEM does with many collaborators all of the world and discuss the farther collaboration between GEM and CEA (China Earthquake Administration). This session will be hosted by Professor Gao Mengtan from CEA and Doctor Marco Pagani from GEM Foundation.
