Projects CRAVE Collaborative Risk Assessment for Volcanoes and Earthquakes (CRAVE) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Summary The need to better understand the existing earthquake and volcano risk led to the establishment of the Global Earthquake Model (GEM) and the Global Volcano Model (GVM) network. GEM, founded in Italy in 2009, has been developing open tools and models to calculate and communicate seismic hazard and risk worldwide. Similarly, the GVM network represents an international community aiming to provide systematic evidence, data and analysis of volcanic hazards and risk on national, regional and global scales working with monitoring institutions to implement the best science and DRR strategies. Both GEM and the GVM network are currently leading international efforts that aim to mitigate the adverse effects from these perils. South America and ASEAN regions have been the target of numerous studies in the last two decades. However, most of these studies only focused on one component of the risk problem (e.g. hazard, vulnerability). Such limitation prevents the development of a comprehensive risk profile to properly inform decision-makers. The CRAVE project, through the current GEM and GVM network tools will offer a timely and unique opportunity to advance the understanding of seismic and volcanic risk in the region. Objectives This project aims to develop a common framework for the assessment of the impact from earthquakes and volcanoes, with an application in three countries located around the Pacific Rim. The activities comprised in this project feature several events to bring together global partners with the mandate to calculate and communicate seismic and volcanic risk, as well as training events to increase the capacity of local institutions in the assessment of their hazard and risk. Collaborators This project includes several partners including the following: British Geological Survey; the Earth Observatory of Singapore (EOS); the University of Edinburgh; the Volcano Disaster Assistance Program (VDAP) of the United States Geological Survey (USGS); and key organizations from the region including: the Colombian Geological Survey; the Philippine Institute of Volcanology and Seismology;(PHIVOLCS); and Badan Geologi (Indonesia). Location Colombia, Indonesia and the Philippines Volcano Scenario tool for OpenQuake The CRAVE project required the implementation of a new calculator in the OpenQuake Engine called ‘multi_risk’, which is able to manage at the same time different types of hazards, specifically ash fall, pyroclastic density currents flow, lava flow and lahar flow, passed as CSV files with headers ‘lon’, ‘lat’, ‘intensity’. The calculator is also able to consider the difference between dry and wet ash by setting the `ash_wet_amplification_factor` parameter in the job.ini file. The output of the calculator is a CSV file with ‘Exposure + Risk’ fields. For convenience we also produced a ‘Total Risk’ output which is simply the sum over the assets of the values in the ‘Exposure + Risk’ output. In order to support other formats used in the volcanic hazard community we prepared tools to convert hazard footprints into the format accepted by the OpenQuake-engine. These tools were included in the Input Preparation Toolkit. [Software ] Volcano Model example Full example of the volcano model developed with the Servicio Geológico Colombiano (SGC).

Projects BEYOND BUTTON PUSHING Earthquake Risk Assessment and Sensitivity Analysis for California Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The goal of the project was to show how important the quantification of uncertainty is in estimating and understanding California’s earthquake risk using OpenQuake - GEM Foundation’s state-of-the-art open source earthquake hazard and risk assessment software. With OpenQuake’s plug-and-play capabilities, expert users can individually select or substitute every model component, data, and assumption. This feature will help model users and decision makers to: 1) ‘ask the right questions’ when evaluating model results; 2) better interpret risk assessment results and gain trust in model results; and 3) make better risk management decisions. Duration: 2015-2017 Objectives The main objectives of this project are to: Establish representative sets of exposure: ‣ for the San Francisco Bay Area; ‣ for the Southern California region affected by the Shakeout Scenario Choose specific results (risk metrics) to use as a basis for comparison. Produce ‘baseline’ results from OpenQuake, using a ‘control’ set of assumptions. Undertake a thorough sensitivity analysis for the risk estimates for California based on the UCERF3 model by running OpenQuake multiple times, each time varying one assumption or parameter, such as: ‣ earthquake probabilities (controlled by assumptions about fault geometries, slip rates, maximum magnitudes); ‣ ground motion model selection; ‣ vulnerability functions; ‣ site conditions; and ‣ statistical treatment of uncertainty and correlation Beyond the aims stated at the outset of the project as listed above, several additional objectives were achieved during the course of the project, including the following: Implement within OpenQuake the latest seismic hazard model for California based on the recently published Uniform California Earthquake Rupture Forecast version 3 (UCERF3), produced by the U.S. Geological Survey and the Working Group on California Earthquake Probabilities. Calculate the average annual loss estimates for all 8,057 census tracts in California, using the seismic hazard model based on UCERF3. Establish the range (distribution) of scientifically viable results for the chosen risk metrics by accounting for the various uncertainties in the hazard model. Identify the components of the hazard model contributing most to the overall uncertainty in the risk metrics for the different exposure portfolios. Implement a model simplification (‘logic-tree trimming’) software tool to reduce the number of computer runs and greatly speed up the time required for running the risk model for California.

Projects SOLOMON ISLANDS EXPOSURE Assessing the Risk Exposure of Road Network to Climate and Natural Hazard Risks in Solomon Islands Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background This project aims to conduct a robust multi-hazard risk assessment of the road network to climate and natural hazards in the Solomon Islands, both historically and under future climate projections. The project includes three main dimensions: - Characterization of the climate and natural hazards - Physical vulnerability of the road network - Multi-criteria criticality analysis The three main outputs are: - Multi-hazard maps - Road network risk exposure analysis (global risk score) - Identification of "first priority" road segments and estimation of their rehabilitation costs The GEM Hazard Team supports the project by computing seismic hazard maps and uses these to produce maps to classify low to high risks of earthquake hazards, according to their intensity and frequency. Duration: 2021 Objectives Many Small Island Developing States (SIDS) share a major common feature: they are among the most exposed nations to natural hazards and climate change. SIDS are also characterized by insularity and geographic remoteness, as well as small geographic area, economies, and population, all of which increase their social and economic vulnerability. This project aims to assist the Solomon Islands to better manage climate and disaster risks by improving the understanding of risk and the use of this information for risk reduction decision-making, and the design and implementation of investments at the provincial and community level.

Projects TREAD daTa and pRocesses in sEismic hAzarD Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background GEM is one of the partners of the Marie Skłodowska-Curie Actions (MSCA) funded TREAD project, which involves a consortium of 14 academic institutions and 8 private partners of the highest scientific level from 7 European countries. TREAD will train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. During the 4 year project GEM will host and supervise two PhD students, one working with the hazard team and the other with the risk team, on the following topics: 1. Modelling distributed seismicity under innovative approaches (under joint supervision with the University of Milano, Bicocca, 2. Assessment of the impact of advanced seismic hazard modelling approaches on earthquake risk (under joint supervision with the University of Chieti-Pescara) More information at https://tread-horizon.eu/ . Duration: 2023-2027 Objectives The aim of TREAD is to train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. A change of paradigm in seismic hazard is necessary to be able to fully account for the specific properties of earthquake source and seismic modes in those areas. For example, to calculate the probability of having multiple earthquake ruptures, the interaction between active faults across various space-time scales needs to be accounted for, as well as the effects of stress transfer and fault-fluid interaction in earthquake triggering. TREAD objectives are: 1) Developing a novel integrative approach to seismic hazard analysis in Europe and the Mediterranean by bridging the gap from small-scale laboratory experiments to large-scale observations. 2) Establishing physics-based earthquake modelling by linking computational modelling of earthquakes from millions of years to fractions of a second. 3) Transferring earthquake geology and computational modelling to hazard and risk assessment adapted to the needs of government, industry and scientific stakeholders.
