- Celebrating Achievements and Way Forward
Latest News Celebrating Achievements and Way Forward READ MORE Photo caption: GALLERY RELATED CONTENTS RELATED CONTENTS As GEM’s first Working Programme (2009-2013) draws to a close, the GEM Foundation presents to partners, collaborators and stakeholders worldwide, ”Celebrating achievements & looking forward”, GEM vision document for global earthquake risk assessment and a sustainable future for GEM. ”The document celebrates GEM’s journey from the idea of a handful of determined individuals, to what has now become a global community, a solid reality and an authoritative voice in earthquake risk assessment globally” said Rui Pinho, GEM Secretary-General. Right from its inception, GEM chose the less travelled road to increase earthquake resilience, building its work and community around the principles of openness, transparency, inclusiveness, equitable access, solid science and collaborative work across sectors, geographies, and disciplines. At the end of GEM’s first Working Programme, GEM’s unique approach has proven to be the right one; the breadth and wealth of tools and resources developed and being developed, through the involvement of global scientists and stakeholders, is advancing the science and technology needed for global state-of-the-art seismic hazard and risk modelling, data collection, and risk assessment at scales from global, to regional and national. This strategic document shares the successes but also the challenges and the issues that GEM needs to address as it moves towards its second Working Programme (2014-2018). Long-term impact and sustainability are crucial for the achievement of GEM’s mission. From 2014 onwards, GEM’s focus will shift towards practical implementation, public communication and development of datasets and tools at a local scale, to increase the applicability of the products in the OpenQuake platform for reliable risk mitigation. GEM will look at different collaboration opportunities in order to permeate different levels of risk management, and transfer and translate GEM products into accessible resources at different levels of governance from global to regional, to local. With the support of current and future partners, collaborators and stakeholders worldwide, GEM will continue to engage in a wide range of partnerships to advance the science required to assess the risk of the complex interconnected systems within which we live, and increase resilience to earthquakes globally.

- What role will GEM play as the risk landscape and associated demand evolve between now and 2030?
Latest News What role will GEM play as the risk landscape and associated demand evolve between now and 2030? READ MORE Photo caption: GALLERY RELATED CONTENTS RELATED CONTENTS A world that is resilient to earthquakes and other natural hazards will continue to be GEM’s vision over the next decade. The mission to 2030 also calls for GEM to become a global leader in the integrated, multi-hazard risk assessment and resilience planning domain. GEM’s strategy and roadmap to 2030 is underpinned by the global drivers for disaster risk reduction and sustainability - namely the Sendai Framework, the Paris Agreement on climate change, and the Sustainable Development Goals – and by its four core values: openness, collaboration, public good and credibility. GEM’s approach is further placed in the context of the evolution of the science and technology of risk modelling and user needs to address systemic and cascading risks for multi-hazards. GEM plans to maintain its global leadership in earthquake hazard and risk assessment, while at the same time leveraging its broader capabilities, such as in exposure modelling, into partnerships addressing the effects of climate change. GEM will also leverage its public-private partnership approach and collaboration network to support the development of risk solutions and improve resilience including through insurance/risk financing, as well as risk mitigation and reduction through urban planning and building regulation.

- Fault2SHA 3rd Workshop: Role of scaling laws & fault interaction
Latest News Fault2SHA 3rd Workshop: Role of scaling laws & fault interaction READ MORE Photo caption: GALLERY RELATED CONTENTS RELATED CONTENTS The event gathered scientists working on earthquake hazards from a variety of perspectives: fault mappers, seismologists, hazard modelers, theoretical geophysicists, and engineers.The presentations by keynote speakers illustrated many challenges in understanding the distribution of earthquakes in time and space. However they also noted that through careful data collection and analysis, progress is being made on important topics such as fault segmentation and earthquake clustering. In addition, the work by the hazard modelers shows that the constantly improving hazard engines such as OpenQuake and skills of the modelers are capable of dealing with the complexities of earthquake occurrence. The group believes that the main challenges in estimating earthquake hazards lie in the scientific rather than technical aspects. Underscoring the value of openness and transparency, Richard Styron, GEM Active Fault Specialist says, “The level of communication and mutual interest was high among participants throughout the workshop, and there is widespread support for the creation of natural laboratories where observational scientists and modelers can share data and ideas, and test hypotheses, in an open and mutually supportive environment.” The FAULT2SHA is a Working Group formally approved by the European Seismological Commission during its 35th General Assembly in September 2016. It is open to all researchers interested in contributing to discussions on topics that could improve the assessment of seismic hazard.

- GEM and 100RC partnership to boost earthquake resilience
Latest News GEM and 100RC partnership to boost earthquake resilience READ MORE Photo caption: GALLERY RELATED CONTENTS RELATED CONTENTS Cities at risk to earthquakes are expected to directly benefit from the partnership between GEM and 100 Resilient Cities – Pioneered by The Rockefeller Foundation (100RC), which is dedicated to helping cities around the world become more resilient to the physical, social and economic shocks and stresses of the 21st century. (source: http://www.100resilientcities.org ) The agreement signed in August provides an opportunity for 100RC member cities to understand and address their earthquake risk by working with GEM to incorporate earthquake risk reduction in their resilience strategies and capturing lessons learned to inform other cities. The Global Earthquake Model (GEM) will partner with motivated cities to build their capacity for long-term risk mitigation planning using GEM’s open source OpenQuake software and GEM’s other tools and services. “Our partnership with the 100RC is a great opportunity to share GEM’s open tools, data and technical expertise at the city level. Working together with 100RC is an important step toward achieving GEM’s vision of a world that is resilient to earthquakes.” John Schneider, GEM Secretary General. Cities will receive an ‘Earthquake Risk Thumbnail’, a report providing OpenQuake maps of the city’s or region’s seismic risk comprised of the hazard, and the physical, social and economic risk to the exposed assets and population. 'Thumbnail’ report will propose options for deeper engagement which may include collaboration on data collection, raining local city staff or partners to use GEM’s products and tools, and stakeholder engagement workshops including the Resilience Performance Scorecard (RPS) exercise. Rebecca Laberenne, Associate Director on the Solution Development and Innovation Team at 100RC, underscores the value of partnering with GEM saying, "We are delighted to have GEM Foundation as a 100RC Platform Partner to provide much needed information and technical advice to cities whose buildings and infrastructure are at risk to earthquakes. GEM's approach to collaboration and technical assistance will be very welcomed by cities to gain an understanding of their risks, as well as to assist in identifying appropriate and cost-effective mitigation and risk reduction measures as part of their resilience strategies."

- Local solutions to global problems: reducing disaster risk through collaboration and openness
Latest News Local solutions to global problems: reducing disaster risk through collaboration and openness READ MORE Photo caption: TREQ Team meeting with engineers of the Municipality of Quito, Ecuador. GALLERY RELATED CONTENTS RELATED CONTENTS TREQ Team meeting with engineers of the Municipality of Quito, Ecuador. October 13, 2021. Pavia. The 2021 edition of IDDR Day focuses on ‘International cooperation for developing countries to reduce their disaster risk and disaster losses.’ - the sixth of the Sendai Seven targets. GEM’s work over the past decade in developing countries has accelerated the assessment of risk and incorporation of risk-based decisions into planning and sustainable development by merging the interests of public and private sectors, and collaborating with local governments. John Schneider, GEM Secretary General, underscores GEM’s collaborative and inclusive approach by saying that “GEM develops trust with local partners and stakeholders through projects that provide technical support and training on the use and application of GEM models, tools and methodologies. We ensure that local scientists, experts and local decision-makers are involved from the start.” Most recently, GEM’s Training and Communication for Earthquake Risk Assessment or TREQ Project, funded by USAID, has demonstrated this by GEM working together with local partners in building the capacity for urban earthquake risk assessment in Quito, Ecuador; Cali, Colombia; and Santiago de los Caballeros, Dominican Republic. Building on the success of GEM’s previous collaborative efforts in the South America Risk Assessment project (SARA 2013-2016) and Central America and the Caribbean Risk Assessment project (CCARA 2017-2018), the TREQ team, in collaboration with local experts, has updated the hazard and risk models of the pilot cities using more detailed hazard and risk information. Since 2020, the TREQ team has trained close to 400 individuals from almost 60 countries in using OpenQuake for urban earthquake hazard and risk assessments (https://www.training.openquake.org/ ). The project also produced training and educational materials that are being adapted for university courses through the project’s Training the Trainers component . The results* of the TREQ project will be released openly, and will be of interest to a wide-range of users – from risk analysts, emergency planners and managers to researchers, modelers and the public at large. The analysis methods and collaboration approach set the foundation for enhancing earthquake hazard and risk assessment for other cities and urban areas in Central and South America, and may be extended worldwide to cities at risk and in need of assistance. “The TREQ project has served as a venue for thorough discussion and developing skills in the hazard and risk assessment fields in the region. Working groups established in the cities have facilitated the sharing of data, knowledge, methodologies and results between the local partners and GEM scientists. Over the past two years, we have mutually learned from our diverse backgrounds and experiences.” Catalina Yepes, GEM Project Manager on the importance of local collaboration in disaster risk reduction.

- Global Earthquake Risk Map
Global Earthquake Maps Global Earthquake Risk Map VIEWER PDF PNG CONTRIBUTORS DOCUMENTATION References TECHNICAL DESCRIPTION The Global Seismic Risk Map (v2018.1) comprises four global maps. The main map presents the geographic distribution of average annual loss (USD) normalised by the average construction costs of the respective country (USD/m2) due to ground shaking in the residential, commercial and industrial building stock, considering contents, structural and non-structural components. The normalised metric allows a direct comparison of the risk between countries with widely different construction costs. It does not consider the effects of tsunamis, liquefaction, landslides, and fires following earthquakes. The loss estimates are from direct physical damage to buildings due to shaking, and thus damage to infrastructure or indirect losses due to business interruption are not included. The Global Seismic Hazard Map depicts the geographic distribution of the Peak Ground Acceleration (PGA) with a 10% probability of being exceeded in 50 years, computed for reference rock conditions (shear wave velocity of 760-800 m/s). The Global Exposure Map depicts the geographic distribution of residential, commercial and industrial buildings. The Global Seismic Fatalities Map depicts an estimate of average annual human losses due to earthquake-induced structural collapse of buildings. The results for human losses do not consider indirect fatalities such as those from post-earthquake epidemics. The average annual losses and number of buildings are presented on a hexagonal grid, with a spacing of 0.30 x 0.34 decimal degrees (approximately 1,000 km2 at the equator). The average annual losses were computed using the event-based calculator of the OpenQuake engine, an open-source software for seismic hazard and risk analysis developed by the GEM Foundation. The seismic hazard, exposure and vulnerability models employed in these calculations were provided by national institutions, or developed within the scope of regional programs or bilateral collaborations. These global maps and the underlying databases are based on best available and publicly accessible datasets and models. Due to possible model limitations, regions portrayed with low risk may still experience potentially damaging earthquakes. The GEM Risk Map is intended to be a dynamic product, such that it may be updated when new datasets and models become available. Releases of updated versions of the seismic risk map are anticipated on a regular basis. Additional hazard and risk metrics for each country can be explored at globalquakemodel.org/gem.

- Resilience Performance Scorecard (RPS) in San Jose de Costa Rica
Latest News Resilience Performance Scorecard (RPS) in San Jose de Costa Rica READ MORE Photo caption: GALLERY RELATED CONTENTS RELATED CONTENTS Some 43 community members and 39 officials from San Jose, Costa Rica participated in GEM’s resilience performance and social vulnerability evaluation using GEM’s Resilience Performance Scorecard (RPS). The Municipality of San Jose, the National Commission of Emergencies (CNE) of Costa Rica, the National Laboratory of Materials and Structural Models (LANAME) from the University of Costa Rica and USAID supported the workshop held from June 15-16. The objective was to empower stakeholders of disaster management institutions and leaders of the community to assess earthquake risk and resilience using innovative data collection technologies. This assessment allows the stakeholders to identify the achievements and the gaps in the resilience of the city. The first draft of the report of the results will be ready in September and will be made public once the report has been approved by the Municipality of San Jose and the CNE of Costa Rica. The RPS workshop is part of GEM’s Assessing and Mitigating Earthquake Risk in the Caribbean and Central America (CCARA) Project. The objectives of the project are: to develop capacity in the region of Central America and the Caribbean for earthquake risk assessment by leveraging GEM tools and resources, to enhance the understanding of earthquake risk, and to bridge the gap between risk assessment and disaster risk reduction. GEM’s RPS is being used as an essential step to understand and enhance the resilience of cities to earthquakes by measuring baseline conditions of what makes communities resilient.
