Publications GEM1: OpenGEM System Design Document Share Facebook LinkedIn Download 2010 | Report The aim of this document is to provide an overview of the design of the OpenGEM system, within the scope of the GEM1 project. OpenGEM is the name that was chosen for the IT platform which will allow calculation and communication of earthquake risk on a global scale. One of the goals of the GEM1 project was to design an initial model building structure and this report hence describes the various components of the design. The IT infrastructure described in this report has been reviewed during an intensive IT-review after which a strategy has been determined for further development of GEMs IT architecture, which makes use of the work done during GEM1, but has taken a different approach.

Publications Investment in Disaster Risk Management in Europe Makes Economic Sense Share Facebook LinkedIn Download 2021 | Report The physical, financial, and social impacts of disasters in Europe are growing and will continue to grow unless urgent actions are taken. In the European Union (EU), during the period from 1980 to 2020, natural disasters affected nearly 50 million people and caused on average an economic loss of roughly €12 billion per year (EEA, 2020). The impacts of flood, wildfire, and extreme heat are increasing rapidly, and climate damages could reach €170 billion per year according to conservative estimates for a 3 scenario unless urgent action is taken now (Szewczyk, et al., 2020). Earthquakes, while rare, have a devastating impact on the ageing buildings and infrastructure of Europe that were constructed prior to modern codes; in Bucharest, for example, nearly 90% of the population lives in multifamily buildings with pre-modern building codes3 (Simpson & Markhvida, 2020). Within the EU, the top-five countries with the highest annual average loss to earthquake are Cyprus, Greece, Romania, Bulgaria, and Croatia, and for floods the top-five countries are Romania, Slovenia, Latvia, Bulgaria, and Austria.4 However, disasters do not affect everyone equally: poor, elderly, very young, and marginalized populations are most affected and least able to recover. In Romania, Greece, Croatia, and Bulgaria, for example, the socio-economic resilience of the poor is on average less than 30% of the national average (World Bank, 2020). Moreover, the local and regional administrations in the poorer and more disadvantaged areas have the least capacity to design and implement resilience investments.

El proyecto ha realizado dos visitas al país, reuniendo a agencias gubernamentales, científicos, ingenieros y otras partes interesadas para discutir la evaluación de riesgos sísmicos, el análisis de riesgos y las estrategias de comunicación. ( informe con información detallada ) "Los talleres del proyecto FORCE han sido fundamentales para fortalecer nuestro conocimiento en la gestión del riesgo sísmico. Esto nos permite mejorar la logística mediante el desarrollo y actualización de nuestros instrumentos de planificación basados en escenarios realistas. Estos escenarios definen los recursos necesarios (humanos, materiales y financieros) de antemano, asegurando una respuesta más efectiva y oportuna cuando ocurre un terremoto." - Katherine Elizabeth Peña Nunfio, Especialista Técnica - Investigación y Análisis de Riesgos, Dirección General de Protección Civil. Haga clic aquí para obtener más detalles de las ideas de Katherine. Sesiones de formación y taller técnico de OpenQuake La primera visita, del 6 al 10 de noviembre de 2023, se centró en sesiones de capacitación para el personal del Ministerio de Medio Ambiente y Recursos Naturales (MARN) sobre la construcción de modelos base para la evaluación del riesgo sísmico, como el modelo de peligrosidad sísmica y el modelo de exposición. En el caso de la peligrosidad sísmica, el flujo de trabajo se evaluó utilizando las diferentes herramientas que GEM ofrece para la construcción de un modelo probabilístico de peligrosidad sísmica (PSHA) y los conjuntos de datos subyacentes (catálogo sísmico y árbol lógico de modelos de movimiento del suelo). El Taller Técnico OpenQuake, celebrado el 9 de noviembre de 2023, proporcionó ejercicios prácticos paso a paso sobre el análisis de peligro y riesgo sísmico. Los participantes tuvieron la oportunidad de interactuar con científicos e ingenieros de GEM en la modelación de la peligrosidad y el riesgo sísmico utilizando OpenQuake, el software desarrollado y mantenido por la Fundación GEM, y utilizado por el MARN para la caracterización de la peligrosidad sísmica a nivel nacional. "El MARN reconoce la importancia de actualizar periódicamente sus modelos de peligro y exposición para reflejar los últimos patrones de actividad sísmica y urbanización. La institución continuará utilizando las metodologías GEM y el software OpenQuake para garantizar que sus modelos permanezcan actualizados y confiables." – Luis Ernesto Mixco Durán, MARN sobre las principales conclusiones de los talleres y su implementación.

Recomendaciones clave de los talleres Los talleres identificaron varias recomendaciones clave para mejorar la gestión del riesgo sísmico en El Salvador: Desarrollo de capacidades: Mejorar la experiencia técnica en la evaluación de riesgos sísmicos y la utilización del software OpenQuake, teniendo en cuenta que 40 participantes asistieron al taller de capacitación en línea realizado durante el mes de febrero eran de El Salvador https://www.training.openquake.org/ . Desarrollo de modelos: Mejorar continuamente los modelos de amenaza, exposición y vulnerabilidad para El Salvador. Comunicación de riesgos sísmicos: Desarrollar perfiles de riesgo personalizados para agencias gubernamentales y el público. Utilizar un dashboard para una visualización y difusión efectiva de los resultados. Consideraciones adicionales: Incluir en futuras versiones la estimación de daños a la infraestructura, la fluctuación de la población y la presencia de turistas en las evaluaciones de riesgo. Dar prioridad a la comunicación del riesgo sísmico y a la preparación de la comunidad. Fomentando la colaboración y la aproiación del conocimiento Los talleres de FORCE han hecho una contribución significativa a los esfuerzos de reducción del riesgo sísmico en El Salvador al reunir a las principales partes interesadas en el campo de la preparación para desastres y la respuesta ante emergencias. Estos talleres han fomentado un entorno de colaboración en el que los participantes pueden compartir sus conocimientos y experiencia, lo que ha llevado a una mejor comprensión de los peligros sísmicos, los métodos de evaluación de riesgos y las estrategias de comunicación adecuadas.

Publications Ranking and developing ground-motion models for Southeastern Africa Share Facebook LinkedIn Download 2024 | Peer-reviewed The southern East African Rift System (EARS) is an early-stage continental rift with a deep seismogenic zone. It is associated with a low-to-moderate seismic hazard, but due to its short and sparse instrumental record, there is a lack of ground-motion studies in the region. Instead, seismic hazard assessments have commonly relied on a combination of active crustal and stable continental ground-motion models (GMMs) from other regions without accounting for the unusual geological setting of this region and evaluating their suitability. Here, we use a newly compiled southern EARS ground-motion database to compare six active crustal GMMs and four stable continental GMMs. We find that the active crustal GMMs tend to underestimate the ground-motion intensities observed, while the stable continental GMMs overestimate them. This is particularly pronounced in the high-frequency intensity measures (>5 Hz). We also use the referenced empirical approach and develop a new region-specific GMM for southern EARS. Both the ranked GMMs and our new GMM result in large residual variabilities, highlighting the need for local geotechnical information to better constrain site conditions.
