News Social Vulnerability Workshop: Making recovery and resilience modeling useful for decision makers and local stakeholders By: Jul 31, 2019 Share Facebook LinkedIn Social Vulnerability workshop participants - June 18-19, 2019 More than 20 individuals from NGOs, academia, private and public sectors from US, Canada, Australia, Nepal, China, Germany and Switzerland participated in GEM’s Social Vulnerability workshop held from 18th to 19th of June 2019 in Pavia, Italy. The aim of the 2-day workshop was to review the methodology and tools for social vulnerability modeling, and to outline future interdisciplinary directions and opportunities for integrating hazard, built-environment, and social dimensions of earthquake risk into a single measurement framework that takes into account quantitative, ‘top-down and stakeholder-based, bottom-up’ approaches. The workshop also set in motion GEM’s plan to release a Global Social Vulnerability and Integrated Risk (SVIR) map in December this year. Dr. Christopher Burton of Auburn University, USA and GEM’s former SVIR Team Coordinator, facilitated the 2-day workshop and is working with GEM to complete the global SVIR map. Areas of model improvement: perspectives of participants Participants identified four key areas that need to be addressed to improve the current SVIR metrics, models and tools to ensure its usefulness at the local level. These are: integration of risk and hazard with social vulnerability modeling; addition of statistical and technical capabilities to GEM’s Integrated Risk Modeling Toolkit (IRMT) and training of its users; using Resilience Performance Scorecard (RPS) as a metric by interlinking it with real data such as no. of hospital beds; and updating of Recovery Modeling Tools to include other hazards such as fire and floods. “Social vulnerability modeling is most useful for the public sector. Nonetheless, any model with a business interruption component would be good for the insurance sector,” Alex Allman, Munich Re underscoring the value of social vulnerability models in the private and public sectors. GEM social vulnerability and resilience: future directions To address the gaps between risk dimensions and stakeholder needs, the group agreed that there is an urgent need to improve communication of existing tools, methods and models with GEM partners and organizations working on similar initiatives in order to encourage stakeholders to use and contribute to its future development. Developing basic standards for data and methods for resilience and social vulnerability modeling by integrating current and future work into all aspects of the disaster risk reduction (DRR) cycle – prevention, preparation, response and recovery was also considered an important component for future models. By having basic standards, others can conduct assessments at sub-national level. Other aspects that need attention in the near future are: multi-hazard resilience at community, infrastructural and institutional levels; identification of where indirect economic losses are likely to occur and which areas are most vulnerable; and understanding the drivers of business resilience and recovery within different industries. What’s next Several technical papers will be prepared in the coming months as well as an SVIR program plan to outline the way forward for GEM’s work in the field of social vulnerability and integrated risk.

Publications Modeling distributed seismicity for probabilistic seismic_hazard analysis: Implementation and insights with the OpenQuake engine Share Facebook LinkedIn Download 2014 | Peer-reviewed In any probabilistic seismic‐hazard model, the earthquake activity that cannot be associated with well‐characterized fault structures is taken into account as seismicity distributed over a geographical region. Ground‐motion prediction equations (GMPEs) are generally based on predictor variables describing the spatial extension of a rupture. The approach taken to model rupture finiteness can therefore bias the estimation of seismic hazard. We study the effect of rupture finiteness in modeling distributed seismicity using the OpenQuake (OQ) engine, the open‐source software for seismic hazard and risk assessment promoted by the Global Earthquake Model initiative. For a simple test case we show how the inclusion of rupture finiteness, with respect to the point‐rupture approximation, leads to a significant increase in the probabilities of exceedance for a given level of motion. We then compare the OQ engine with the calculation software developed by the U.S. Geological Survey‐National Seismic Hazard Mapping Project. By considering a gridded seismicity model for California, we show how different approaches for modeling finite ruptures affect seismic‐hazard estimates. We show how sensitivity to rupture finiteness depends not only on the spatial distribution of activity rates but also on the GMPE model. Considering two sites in Los Angeles and San Francisco, we show that for a return period of 475 years, the percent difference in the associated ground‐motion levels when using point and finite ruptures ranges from 19% to 46%; for a return period of 2475 years the difference ranges from 29% to 58%.

Publications Model of seismic design lateral force levels for the existing reinforced concrete European building stock Share Facebook LinkedIn Download 2021 | Peer-reviewed As part of the development of a European Seismic Risk Model 2020 (ESRM20), the spatial and temporal evolution of seismic design across Europe has been studied in order to better classify reinforced concrete buildings (which represent more than 30% of the approximately 145 million residential, commercial and industrial buildings in Europe) and map them to vulnerability models based on simulated seismic design. This paper summarises the model that has been developed to assign the years when different seismic design levels (low code, moderate code and high code) were introduced in a number of European countries and the associated lateral forces that were specified spatially within each country for the low and moderate codes for typical reinforced concrete mid-rise buildings. This process has led to an improved understanding of how design regulations evolved across Europe and how this has impacted the vulnerability of the European residential building stock. The model estimates that ~ 60% of the reinforced concrete buildings in Europe have been seismically designed, and of those buildings ~ 60% have been designed to low code, ~ 25% to moderate code and 15% to high code. This seismic design model aims at being a dynamic source of information that will be continuously updated with additional feedback from local experts and datasets. To this end, all of the data has been made openly available as shapefiles on a GitLab repository.

News GEM presents the OpenQuake-engine at the 12th International Geoscience Conference, Saudi Arabia By: Jul 2, 2018 Share Facebook LinkedIn GEM’s Marco Pagani and Valerio Poggi recently conducted a 1-day workshop to introduce the hazard component of the OpenQuake-engine (OQ-engine) at the 12th International Geoscience Conference from February 4-7, 2018 in Jeddah, Saudi Arabia. This year’s event, organized by the Saudi Geological Survey (SGS) and Saudi Society for Geosciences, attracted geoscientists and experts not just from the Arab states but from countries around the region and beyond as well. More than 30 workshop participants got to observe and experience the key features of the OQ-engine. The morning session focused on theories describing the main characteristics of the hazard component and the information composing a hazard input model. The afternoon session focused on the calculation of hazard, initially illustrating the main characteristics of the Saudi Arabia National hazard model and subsequently performing some calculations using the model and demonstrating simple use cases. The workshop organizer, SGS said the OQ-engine is indeed a very powerful tool for seismic hazard calculation and what sets it part from the other software is that it is truly open and accessible to all. Other participants shared the same view and expressed interest to use the OQ-engine in the future. To download the OQ manual and installer, click here. Marco and Valerio met Hani M. Zahran and Vladimir Sokolov of the SGS after the workshop to discuss and explore future work and collaboration in the Arabian peninsula. Recently, the GEM Foundation hazard team completed the latest seismic hazard model for Saudi Arabia using the OQ-engine in collaboration with the SGS. Though the hazard model is for a moderate seismicity area, the implementation nonetheless posed a number of challenges and difficulties (e.g. the interactions with volcanic processes in proximity to the Red sea), which GEM and SGS hope to further address in future collaborative undertakings. “The conference is a good opportunity for GEM to further strengthen its network in the Arabian region. It has given us the chance to meet representatives from SGS for the first time; although in the recent past, we have collaborated with them to implement the OQ-engine for the Saudi hazard model. The meeting opened new doors and possibilities of expanding GEM’s work in the Arabian Peninsula,” Marco Pagani reflecting on the value of GEM’s participation to the conference. The main objective of the annual conference is to advance knowledge and cooperation in Earth Sciences across the Arabian region to facilitate research in emerging fields, to build strong links between academia, industry and eco/geo/archeological tourism, and to foster long-term sustainable development of the Arab region.

News CRAVE ‘Twin’ Workshops in Colombia and Indonesia By: May 23, 2019 Share Facebook LinkedIn CRAVE workshop participants - Indonesia. Photo credit: IT Bandung Bogota, Colombia Members of the USAID-supported project – Collaborative Risk Assessment for Volcanoes and Earthquakes or CRAVE from Colombia participated in a 2-day workshop to discuss volcanic threats and risks. The Servicio Geológico Colombiano (SGC) hosted the workshop from May 15-16, 2019. The workshop was divided into two parts: a morning session focused on earthquake and volcanic hazard and risk in Colombia, where the SGC, the National Unit for Disaster Risk Reduction in Colombia (UNGRD) and the GEM Foundation presented to a general audience the achievements and challenges that the country currently faces. This session was attended by 40 people representing seven governmental institutions (Ministry of Housing, Ministry of Environment, Department of National Planning, National Administrative Department of Statistics, and Instituto Distrital de Gestión de Riesgos y Cambio Climático), and 20 experts from the three main volcanological observatories in Colombia (Manizales, Popayan and Pasto). The second part of the workshop focused on the technical aspect of volcanic hazard and risk assessment using hazard footprints for four volcanic hazard components: lava flow, lahar, pyroclastic density currents, and ash fall. OpenQuake tools for volcanic risk analysis were used for the Ruiz Volcano pilot case and hazard footprints were discussed for five other volcanoes (Galeras, Puracé, Azufral, Cumbal and Chiles). For volcanic threats, participants agreed that the hazard products to be developed must be adapted to the needs of risk assessment in order to arrive at a more realistic view of risk. It was also mentioned that more technical discussion is needed for the probabilistic modelling of other volcanic phenomena e.g. ash fall to establish realistic probabilities or rates of occurrence of such phenomena. The discussion on volcanic risk highlighted the importance of factoring in communication and social risk metrics such as damage to roads and airports and access to clean water, as they can significantly impact the modification/adjustment or formulation of risk management strategies. Bandung, Indonesia In the following week, a similar event took place in Bandung (Indonesia), with support from the Institute of Technology of Bandung (ITB). The event featured a day of presentations and discussion with representatives from the Center for Volcanology and Geological Hazard Mitigation (CVGHM), the Indonesian Ministry of Public Works, the National Disaster Management Agency (Badan Nasional Penanggulangan Bencana - BNPB), the Meteorology, Climatology and Geophysics Agency (Badan Meteorologi, Klimatologi dan Geofisika - BMKG), the Philippine Institute of Volcanology and Seismology (PHIVOLCS) and the British Geological Survey (BGS). This part of the workshop provided an opportunity to discuss and better understand the current gaps in volcano, earthquake and tsunami hazard and risk assessment in the region and beyond. On the second day of the event, 40 participants employed OpenQuake for the estimation of economic losses and damage due to earthquake and volcano scenarios. The participants highlighted the need for open tools for risk assessment and to share data concerning exposure and disaster loss to improve or calibrate existing models. Data such as exposure and disaster loss are required for monitoring of the Sendai Framework for Disaster Risk Reduction. CRAVE is funded by USAID to develop a common framework for the assessment of the impact from earthquakes and volcanoes, with the support of experts from the Philippines, Indonesia, Colombia, United Kingdom and Singapore.

Publications Exploring the impact of spatial correlations and uncertainties for portfolio analysis in probabilistic seismic loss estimation Share Facebook LinkedIn Download 2014 | Peer-reviewed The significant potential for human and economic losses arising from earthquakes affecting urban infrastructure has been demonstrated by many recent events such as, for example, L’Aquila (2009), Christchurch (2011) and Tohoku (2012). Within the current practice of seismic loss estimation in both academic and industry models, the modelling of spatial variability of the earthquake ground motion input across a region, and its corresponding influence upon portfolios of heterogeneous building types, may be oversimplified. In particular, the correlation properties that are well-known in observations of ground motion intensity measures (IMs) may not always be fully represented within the probabilistic modelling of seismic loss. Using a case study based on the Tuscany region of Italy, the impacts of including spatially cross-correlated random fields of different ground motion IMs are appraised at varying spatial resolutions. This case study illustrates the impact on the resulting seismic loss when considering synthetic aggregated portfolios over different spatial scales. Inclusion of spatial cross-correlation of IMs into the seismic risk analysis may often result in the likelihood of observing larger (and in certain cases smaller) losses for a portfolio distributed over a typical city scale, when compared against simulations in which the cross-correlation is neglected. It can also be seen that the degree to which the spatial correlations and cross-correlations can impact upon the loss estimates is sensitive to the conditions of the portfolio, particularly with respect to the spatial scale, the engineering properties of the different building types within the portfolio and the heterogeneity of the portfolio with respect to the types.
