Using Socio-economic Indicators for Earthquake Recovery Prediction. Earthquake Spectra, 34: 265-282. TECHNICAL DESCRIPTION The Recovery/Reconstruction Potential Map is closely aligned with the concept of disaster resilience. Enhancing a country’s resilience to earthquakes is to improve its capacity to anticipate threats, to reduce its overall vulnerability, and to allow its communities to recover from adverse impacts from earthquakes when they occur. The measurement of recovery and reconstruction potential includes capturing inherent conditions that allow communities within a country to absorb impacts and cope with a damaging earthquake event, such as the density of the built environment, education levels, and political participation. It also encompasses post event processes that facilitate a population’s ability to reorganize, change, and learn in response to a damaging earthquake. Criteria for indicator selection To choose indicators contextually exclusive for use in each map, the starting point was an exhaustive review of the literature on earthquake social vulnerability and resilience. For a variable to be considered appropriate and selected, three equally important criteria were met: - variables were justified based on the literature regarding its relevance to one or more of the indices. - variables needed to be of consistent quality and freely available from sources such as the United Nations and the World Bank; and - variables must be scalable or available at various levels of geography to promote sub-country level analyses. This procedure resulted in a ‘wish list’ of approximately 300 variables of which 78 were available and fit for use based on the three criteria. Process for indicator selection For variables to be allocated to an index, a two-tiered validation procedure was utilized. For the first tier, variables were assigned to each of the respective indices based on how each variable was cited within the literature, i.e., as being part of an index of social vulnerability, economic vulnerability, or recovery/resilience. For the second tier, machine learning and a multivariate ordinal logistic regression modelling procedure was used for external validation. Here, focus was placed on the statistical association between the socio-economic vulnerability indicators and the adverse impacts from historical earthquakes on a country-by country-basis. The Global Significant Earthquake Database provided the external validation metrics that were used as dependent variables in the statistical analysis. To include both severe and moderate earthquakes within the dependent variables, adverse impact data was collected from damaging earthquake events that conformed to at least one of five criteria: 1) caused deaths, 2) caused moderate damage (approximately $1 million USD or more), 3) had a magnitude 7.5 or greater 4) had a Modified Mercalli Intensity (MMI) X or greater, or 5) generated a tsunami. This database was chosen because it considers low magnitude earthquakes that were damaging (e.g., MW >=2.5 & MW<=5.5) and contains socio-economic data such as the total number of fatalities, injuries, houses damaged or destroyed, and dollar loss estimates in $USD. Countries not demonstrating at least a minimal earthquake risk, i.e., seismicity <0.05 PGA (Pagani et al. 2018) and <$10,000 USD in predicted average annual losses (Silva et al. 2018) were eliminated from the analyses so as not to include countries with minimal to no earthquake risk. A total study area consists of 136 countries. The Global Earthquake Model (GEM) Foundation The Global Socio-Economic Vulnerability Maps 2020 is a product of the GEM Foundation’s collaborative work with the Department of Geography at the University of Connecticut, USA. GEM is a non-profit foundation in Pavia, Italy funded through a public-private partnership with a vision to create a world that is resilient to earthquakes.

  • Enhancing Disaster Resilience: GEM's Role in Malawi's Multi-Hazard Risk Project - GEM Foundation

    News Enhancing Disaster Resilience: GEM's Role in Malawi's Multi-Hazard Risk Project By: Sep 29, 2023 Share Facebook LinkedIn Malawi has embarked on a critical multi-hazard risk assessment project supported by the World Bank. This initiative seeks to strengthen the nation's disaster resilience by assessing the potential impact of various hazards comprehensively. The project, executed by a consortium of partners, is geared towards enhancing disaster risk management (DRM) in Malawi. The primary objective is clear: to empower Malawi with tools and knowledge to mitigate the diverse risks it faces. To achieve this, the consortium, comprised of GEM, CIMA, BGS and Malawi University of Business and Applied Sciences (MUBAS) emphasizes collaboration and stakeholder engagement. Identifying and integrating stakeholder needs and priorities is central to the project's approach. The challenges are substantial. Malawi's limited hazard and risk assessment capacity can pose significant hurdles. These challenges require concerted efforts to improve risk science and develop the country's capacity in these areas. The project's multi-hazard focus aligns with the Malawi Growth and Development Strategy (MGDS III), aimed at strengthening population resilience and reducing vulnerability. Capacity development plays a pivotal role. The project leverages local institutions and academia to enhance capabilities in the next 2 years. Additionally, it recognizes the link between humanitarian needs and the risk-development nexus. Ensuring youth and gender balance is a priority, promoting their meaningful engagement in DRM efforts. GEM, in close collaboration with Malawian experts, assumes a crucial role in this endeavour. GEM's responsibilities encompass seismic hazard and risk assessment, exposure development, physical vulnerability analysis, and social vulnerability assessment as well as database design and metadata interoperability standards. GEM’s work involves looking into local construction practices and understanding the intricate factors contributing to social vulnerability. Together with local experts, they aim to build a comprehensive risk assessment framework that reinforces Malawi's resilience in the face of a range of hazards. This project signifies Malawi's commitment to proactive disaster risk management, harnessing the consortium’s expertise to fortify the nation's ability to withstand and respond to diverse risks effectively.

  • Calculation of National Seismic Hazard Models with Large Logic Trees: Application to the NZ NSHM 2022 | GEM Foundation

    Publications Calculation of National Seismic Hazard Models with Large Logic Trees: Application to the NZ NSHM 2022 Share Facebook LinkedIn Download 2023 | Peer-reviewed National‐scale seismic hazard models with large logic trees can be difficult to calculate using traditional seismic hazard software. To calculate the complete 2022 revision of the New Zealand National Seismic Hazard Model—Te Tauira Matapae Pūmate Rū i Aotearoa, including epistemic uncertainty, we have developed a method in which the calculation is broken into two separate stages. This method takes advantage of logic tree structures that comprise multiple, independent logic trees from which complete realizations are formed by combination. In the first stage, we precalculate the independent realizations of the logic trees. In the second stage, we assemble the full ensemble of logic tree realizations by combining components from the first stage. Once all realizations of the full logic tree have been calculated, we can compute aggregate statistics for the model. This method benefits both from the reduction in the amount of computation necessary and its parallelism. In addition to facilitating the computation of a large seismic hazard model, the method described can also be used for sensitivity testing of model components and to speed up experimentation with logic tree structure and weights.
