News GEM-World Bank/GFDRR-DFID challenge fund projects kick off By: Jul 2, 2018 Share Facebook LinkedIn The GFDRR-DFID Challenge Fund projects on the development of exposure, vulnerability and hazard footprints databases kicked off with a 2-day inception workshop held at GEM Headquarters from 10-11 April 2017. Several organizations attended the workshop led by World Bank’s GFDRR, British Geological Survey (BGS), GEM Foundation and the University College London (UCL). BGS leads the development of a data schema and data for a multi-hazard database (Challenge 1) while GEM and University College London lead the development of a global exposure database (Challenge 2) and open vulnerability platform for evaluating risk (Challenge 3) respectively. GEM also contributes to Challenge Fund 1 and 3. The goal of the workshop is to integrate the three Challenge Funds so that the final product contributes to the broader objectives of the building evidence for action on disaster risk management and the Sendai Framework. Alanna Simpson, Senior Disaster Risk Management Specialist and leader of the GFDRR Labs team notes that “GEM has done very well in the development of earthquake exposure data” but added that “the idea of the three Challenge Funds is for people to collect information - hazard, exposure and vulnerability - on the built environment at the same time for multiple perils.” She further adds that “the projects would not only develop an exposure database schema that will allow people to collect data only once for many purposes, but would also look into how this framework would be flexible enough to take the top down and bottom up information, including official and non-official data so that they can be used to build the whole picture.” The GFDRR-DFID Challenge Fund seeks to bridge the gap between technology and on-the-ground user needs in the field of disaster risk identification. The Global Facility for Disaster Reduction and Recovery (GFDRR) is a global partnership that helps developing countries better understand and reduce their vulnerability to natural hazards and climate change.For more information, visit https://www.gfdrr.org and https://www.gfdrr.org/the-challenge-fund .

John met and discussed potential partnerships with key representatives of national governments, as well as representatives of the academic and private sectors. TNB Malaysia considering OpenQuake for earthquake hazard and risk assessmentOn May 7th, John was invited by the research arm of the Malaysian national energy company, TNB, to visit their campus in Kuala Lumpur and to give a presentation on GEM. TNB is in the process of assessing the earthquake hazard and risk of their critical energy infrastructure for electric power generation and transmission and is interested in partnering with GEM and learning to use OpenQuake to further develop their capacity for hazard and risk assessment. The project is led by Prof. Azlan Adnan of the University of Technology Malaysia (UTM), who also led a delegation and coordinated a visit to GEM’s headquarters in Pavia, Italy recently. Malaysia has seen a significant increase in earthquake activity since the 2004 M 9.3 Indian Ocean earthquake and tsunami. As a result, they have been rapidly developing the science and engineering capability to address this new hazard, and in 2017 the government put in place their first building code provisions for earthquake safety. The GEM presentation was attended by members of the project team at TNB, the University of Technology, Malaysia, as well as by representatives of the national meteorological agency (also responsible for earthquake monitoring) and the national disaster management agency. TNB is keen to develop a public-private partnership to form a national Malaysian sponsorship of GEM and will work with GEM to develop a proposal. Indonesia keen to join GEM and the USAID-supported CRAVE Project. On May 11th, John visited the Department of Public Works (PUSKIM) of Indonesia research facility in Bandung, 300 km west of Jakarta on the island of Java. PUSKIM has the lead responsibility for the development of the latest national earthquake hazard model and map of Indonesia, which was published in September 2017. The work was accomplished through the National Committee for Seismic Hazard, a coordination of several academic and technical organizations, and chaired by Prof. Mahsyur Irsyam of the Institute of Technology, Bandung (ITB). He also served as one of the review panel members for GEM’s Global Earthquake Hazard and Risk Model due for release on 5th December this year. The new national hazard model was developed using a combination of Open Quake and the PSHA code developed by the USGS. John met with Prof Irsyam and with Pak Lufti Faisal, Head of Engineering Department, and Pak Arief Subaruddin, Director of Research Institute for Housing and Human Settlement. Public Works has agreed to provide the national hazard model to the GEM global model. They are also keen to become a sponsor of GEM, and will work with GEM to develop a proposal to the Ministry. Also on May 11th, John visited the National Center for Volcanology and Geohazards Mitigation (CVGHM) in Bandung. The purpose was to discuss GEM’s invitation to CVGHM to be a participant in the CRAVE Project, funded by USAID for a pilot project on volcano risk assessment. He met with Devi Syahbana, Team Leader for Volcano Hazard Mitigation in Eastern Indonesia who expressed interest to work with GEM incoordination with the national disaster management agency, BNBP. John also met with several members of the earthquake hazard modeling team, also based at CVGHM: Athanasius Cipta and Amalfi Omang who are OpenQuake users, and did much of the model analysis for the national earthquake hazard map. Both of them did masters degrees at the Australian National University under the supervision of Prof. Phil Cummins, the Geoscience Australia representative to the GEM Governing Board.

News Methods and Tools Innovation for Seismic Risk Assessment project By: Jul 25, 2020 Share Facebook LinkedIn GEM is set to start a 3- year project called METIS or Methods and Tools Innovation for Seismic Risk Assessment funded by the European Commission. The project is part of the program. Electricite De France (EDF), a GEM technical collaborator, is coordinating the project which will be implemented in collaboration with 14 other organizations. The project will start in September 2020 and end in August 2024. The objective of is to translate research into practice through rigorous and efficient methodologies and tools to assess seismic safety of NPP (nuclear power plants). It also aims to innovate current practice by combining simulation with experimental data. The research will develop methods to improve the ability to define safety limits for extremely rare events, which go beyond current design analyses (i.e. design extension for earthquakes). The refined seismic PSA (probabilistic safety assessment) is expected to provide meaningful support in defining regulations for safe design of NPP, as well as for assessing plant safety in real-time in case of temporary unavailability of relevant safety equipment or structures. GEM will contribute to the task on seismic hazard assessment and the one on PSA Tools and Methodology. In the hazard task, GEM will implement into the OQ Engine methods such as vector-valued probabilistic seismic hazard analysis (PSHA), cluster-based PSHA as well as new methods to propagate epistemic uncertainties. Research will also be carried out in the context of processing earthquake catalogues to remove aftershocks and foreshocks and on testing PSHA models. GEM’s contribution to the PSA Tools and Methodology will concentrate on testing risk results. The participation of GEM in this high-level program will not only enhance GEM’s scientific advancement of earthquake hazard analysis using the OpenQuake engine, but will also promote a two-way sharing of knowledge and skills with other project collaborators for the advancement of earthquake hazard assessment to critical infrastructure such as nuclear power plants. The results of this project will help nuclear operators in their periodic safety reviews and to respond to the high-level EU-wide safety objectives of the amended EURATOM nuclear safety directive (stress tests). The considered accident scenarios will provide input for updating severe accident management guidelines (SAMG). No images found. GALLERY 1/2 Gallery VIDEO RELATED CONTENTS
