Publications Risk Modeler's toolkit Share Facebook LinkedIn Download 2015 | User manual The goal of this book is to provide a comprehensive and transparent description of the methodologies adopted during the implementation of the OpenQuake Risk Modeller’s Toolkit (RMTK). The Risk Modeller’s Toolkit (RMTK) is primarily a software suite for creating the input models required for running seismic risk calculations using the OpenQuake-engine. The RMTK implements several state-of-the-art methods for deriving robust analytical seismic fragility and vulnerability functions for single structures or building classes. The RMTK also provides interactive tools for post-processing and visualising different results from the OpenQuake-engine seismic risk calculations, such as loss exceedance curves, collapse maps, damage distributions, and loss maps. The OpenQuake Risk Modeller’s Toolkit is the result of an effort carried out jointly by the IT and Scientific teams working at the Global Earthquake Model (GEM) Secretariat.

Publications Development of a Probabilistic Earthquake Loss Model for Iran Share Facebook LinkedIn Download 2017 | Peer-reviewed Iran is located in one of the most seismically active regions of the world. This high seismicity combined with densely populated regions has led to several destructive earthquakes in the past, such as the M7.4 Tabas (1978), M7.4 Manjil–Rudbar (1990), or the M6.6 Bam (2003). Seismic hazard and risk assessment can provide critical information to decision makers for the development of efficient risk reduction measures. In this study, exposure models for the residential, commercial and industrial building stock were developed using recent housing census information, socio-economic data and the judgement of local experts. For each building class in the exposure model, a set of fragility and vulnerability models was derived using nonlinear time history analysis and ground motion records from the region. The exposure and vulnerability models were combined with the recently released Earthquake Model for the Middle East (EMME) to estimate probabilistic earthquake losses using the OpenQuake-engine. These results identify the regions within the country with the highest risk, the most vulnerable building classes, and the expected economic losses for a number of return periods.

Earthquake Risk Modelling, a bridge between knowledge and application GEM Impact Story Series Early beginnings: realizing the power of earthquakes to change communities I became interested in earthquakes at an early age. It was 1968, I was living in Istanbul Turkey with my family. We were having dinner when all of a sudden, the ground started to shake and things fell to the floor. It was a time of crisis in Istanbul and what struck me was the earthquake changed everything in just a few seconds. People that were at war were all of a sudden in the streets together and I understood the power of earthquakes to change communities. That memory stuck with me. It has influenced my work as a research scientist and motivated a desire to help people understand what could happen in the event of a disaster. First involvement with GEM, earthquake risk in Canada We know that there's potential for significant earthquakes on the west coast on Canada where I live. I work with the Geological Survey of Canada and was introduced to GEM about five years ago at a hazards and risk modeling workshop in Pavia. One of our mandates as a federal research agency is to generate a national earthquake risk assessment for Canada to help inform disaster risk reduction planning and policy development. GEM and Canada partnership A severe earthquake in any of the known hotspots of Canada would strain existing capacities to respond and recover so understanding both the physical and socio-economic risks at a national scale is a priority for us. We don't have a publicly available seismic risk model right now and there is an urgent need to develop a shared understanding at the level of individual communities. GEM provides a suite of tools and expertise that enable us to do risk assessments at all scales - at the national scale, at the regional scale and at the local scale using an open source set of tools that are available to all. Our partnership with GEM enabled collaboration with academic researchers and partners from other organizations to create a team in Canada that is able now to do more than we could have on our own, So, as we progress in generating our national earthquake risk assessment we continue to learn from GEM and hopefully have something to offer back as well. Earthquake risk modelling as a bridge between knowledge and application GEM for me is a community of researchers who share a passion for telling stories about earthquake risks through the use of analytic models. These risk models are a bridge between our understanding of what could happen in the event of a large earthquake and what we can do about it. And so for me working with GEM is working with people who understand in great detail the various aspects of earthquake risk modeling whether it's the hazard models or the vulnerability models, social vulnerability, earthquake risk - all these pieces need to come together in order for us to understand what could happen in the event of a disaster but most importantly what can we do in advance to reduce our risk to earthquakes in the future. GEM as change agent GEM is a change agent in many ways – the most important are the principles on which it's based- the open collaborative nature of GEM is a game changer I think in the field of earthquake risk modeling. By providing open source tools and providing access to a community of experts worldwide, GEM is really accelerating the way in which we think about and model earthquake risk globally, in a way that we haven't been able to do within the context of individual organizations whether that be a national government organization or a private industry organization. Being part of GEM is like being in a jazz band For me being part of the GEM organization is like playing music in a band. You can play classical music where everyone has a part to play and it's scripted and you play your instrument on the appointed time or you can play jazz. Research as a creative design process And when you play jazz with fellow musicians or researchers you learn from each other. You listen to what they're doing, you learn from each other in the moment and your music becomes alive - it changes, it evolves very quickly. It inspires me to think about research as a creative design process. GEM is about bringing together the best science and the best people to advance the best research possible. Supporting GEM means more efficient international collaboration GEM is a nonprofit organization and it offers an invitation for public sector and private sector partners to join an international collaboration to improve our understanding of earthquake risk modeling and ultimately to understand risk better. The incentive for us in Canada to become a member of GEM is pretty simple. The value proposition is very clear. It allows us to do things that we could not do alone as an individual organization and I think many organizations are in a similar position these days. We're all experiencing reduced funding for our research programs, reduced capacities to do the work that we're asked to do. In collaboration however, we have the potential to do this work more effectively. What GEM offers for us is a network of researchers who bring capacity beyond what we have within our own walls to do the work in a way that we couldn't have done otherwise. GEM as a platform for understanding multi-hazard risk in the future I think the value of being a public sector member of GEM is the opportunity to work together as part of a team – and to think about where this collaboration can go in the future. The communities that we work with certainly experience earthquake risk but they also face other hazards of concern: floods, debris flows, other kinds of hazards. And the work that GEM is doing is leading the way I think toward how we as organizations can think about multi hazard risk in a coherent way and use the tools and platform that GEM has assembled over the last 10 years to take us into the future. About the GEM Impact Stories Earthquake risk remains abstract and highly technical, and there are significant risks that due to poor or limited understanding of it, policymakers and the public at large may not be able to fully take advantage of existing and future information that can either help create better or enhance existing earthquake risk reduction and management strategies, especially at the local and national level. Specifically, the GEM Impact Stories project aims to: Collect and document stories where GEM or its partners have contributed to positive change; Encourage policy and decision makers to use science- and evidence- based information to formulate earthquake DRR strategy at the national level through positive stories of change; and Increase awareness of the public at large on earthquake risk and preparedness.

Publications GEM1 Hazard: Description of Input Models, Calculation Engine and Main Results Share Facebook LinkedIn Download 2010 | Report This document provides an overview of the PSHA input models collected during GEM1, of the engine used to perform PSHA calculations, and the methods and criteria adopted for computing a proof-of-concept global hazard map. The GEM1 PSHA input repository contains seventeen national or regional models and one global model based on a smoothed seismicity approach. The oldest models were developed in the context of the GSHAP project, ended at the end of the 1990s; the most recent models are the ones prepared by the USGS-NSHM project for South America and a global smoothed seismicity model specifically produced for GEM1. In terms of geographical coverage the gathered models cover almost all the globe; the only missing regions are the Caribbean, the area around Papua-New Guinea and the Pacific Islands. These areas will hopefully be updated soon in the context of Regional Initiatives. In terms of information content, a relevant part of the PSHA input models is based on area sources while a minority uses fault sources. All the models but the Japanese and the model for the New Madrid Zone in the eastern US incorporate a time independent Poissonian model. Least but not last, epistemic uncertainties are taken into account by just some models, usually the most recent ones, and frequently treated as aleatory in the calculations.
