- Guidelines for Analytical Vulnerability Assessment-Low/Mid-Rise | GEM Foundation
Publications Guidelines for Analytical Vulnerability Assessment-Low/Mid-Rise Share Facebook LinkedIn Download 2014 | Report Guidelines (GEM-ASV) for developing analytical seismic vulnerability functions are offered for use within the framework of the Global Earthquake Model (GEM). Emphasis is on low/mid-rise buildings and cases where the analyst has the skills and time to perform non-linear analyses. The target is for a structural engineer with a Master’s level training and the ability to create simplified non-linear structural models to be able to determine the vulnerability functions pertaining to structural response, damage, or loss for any single structure, or for a class of buildings defined by the GEM Taxonomy level 1 attributes. At the same time, sufficient flexibility is incorporated to allow full exploitation of cutting-edge methods by knowledgeable users. The basis for this effort consists of the key components of the state-of-art PEER/ATC-58 methodology for loss assessment, incorporating simplifications for reduced effort and extensions to accommodate a class of buildings rather than a single structure, and multiple damage states rather than collapse only considerations.

- International Conference for the Decade Memory of the Wenchuan Earthquake - GEM Foundation
News International Conference for the Decade Memory of the Wenchuan Earthquake By: Jul 12, 2018 Share Facebook LinkedIn The 4th International Conference on Continental Earthquakes organized by the China Earthquake Administration (CEA) was held from May 12-14, 2018 in Chengdu, Sichuan, China to commemorate the 10th anniversary of the Wenchuan earthquake. “It has been 10 years since the great earthquake of Wenchuan, Sichuan, southwest China. The impact of that devastating event on either natural science or social sustainability was so important that a decade review will be of no doubt worth for further development,” said Prof. Guoguang Zheng, conference convener and Director of China Earthquake Administration. In line with this, GEM’s Marco Pagani with CEA’s Prof. Mengtan Gao co-organized a session on the activities promoted by Global Earthquake Model. In this session, Anirudh Rao from the GEM Risk Team presented how the OpenQuake engine could be used to assess earthquake risk. Examples of annual average losses, exposure and vulnerability models were presented to emphasize the scientific features of the engine. Anirudh also emphasized the importance of open tools and open data being promoted by GEM. This conference had also been a venue to report the progress of GEM-CEA collaboration to implement China’s national earthquake hazard model on OpenQuake. The collaboration, which started in 2017 hopes to update China’s hazard model for better understanding of future earthquakes in the country. The GEM-CEA technical partnership aims to further fine tune the model for mitigation purposes. In one of the presentations, Professor Tso-Chien Pan from the Institute of Catastrophe Risk Management-NTU Singapore showed a case-study using OpenQuake to investigate the effects of high-resolution location-based exposure data on seismic risk estimates of urbanized regions in Southeast Asia. About the Wenchuan earthquake Sichuan earthquake of 2008, also called Wenchuan earthquake or Great Wenchuan Earthquake, Chinese Wenchuan dizhen or Wenchuan Da Dizhen, massive and enormously devastating earthquake that occurred in the mountainous central region of Sichuan province in southwestern China on May 12, 2008. The epicentre of the magnitude-7.9 quake (measured as magnitude 8.0 by the Chinese) was located near the city of Dujiangyan, about 50 miles (80 km) west-northwest of Chengdu, the provincial capital, at a depth of 11.8 miles (19 km) below the surface. The May 2008 quake flattened some four-fifths of the structures in the affected area. Whole villages and towns in the mountains were destroyed, and many schools collapsed. Almost 90,000 people were counted as dead or missing and presumed dead in the final official Chinese government assessment; the officially reported total killed included more than 5,300 children, the bulk of them students attending classes.(source: https://www.britannica.com/event/Sichuan-earthquake-of-2008) No images found.

Publications Working together to assess risk from global to local: lessons from the Global Earthquake Model Share Facebook LinkedIn Download 2015 | Peer-reviewed Reliable, high-quality risk assessment is the basis for an objective understanding of risk; priority for action 1 of the Sendai framework for disaster risk reduction 2015-2030. It is the foundation of decisions and actions that effectively build resilience. Earthquake risk continues to rise, yet reliable data, risk information, and assessment tools are out of reach or under-utilised in many areas of the world. The Global Earthquake Model (GEM Foundation) was created to bridge these critical gaps. Through authentic collaboration across public and private stakeholders, the GEM community supports risk management and awareness by developing and implementing open risk assessment tools, compiling and generating risk information. GEM influences risk reduction by promoting technology transfer and developing risk assessment capacity. All GEM risk assessment resources are made freely available through its web-based OpenQuake platform. As input to the Sendai framework, this paper provides an overview of GEM's achievements to date, lessons learnt - emphasizing effective modes of collaboration and capacity development -, and presents opportunities and challenges in going forward.
