- TREQ site effects and urban exposure modelling updates - GEM Foundation
News TREQ site effects and urban exposure modelling updates By: Feb 19, 2021 Share Facebook LinkedIn Over the past year, TREQ has made significant progress in the risk and hazard assessments for the selected cities – Santiago, Quito and Cali. This includes the completion of the compilation and preparation of existing PSHA models for hazard calculations; and the development of detailed exposure and vulnerability models. Urban Hazard Assessment For Cali, Colombia, the project improved the national model proposed by Arcila et al. (2020) by adding a new fault located over the city (i.e. Cauca-Cali-Patia fault), consistent with the seismic zonations used in the microzonation study for Santiago de Cali (Ingeominas-Dagma, 2005), and the Colombian building code (AIS, 2009). For Quito, Ecuador, the project selected the model of Beauval et al. (2018), composed of shallow and subduction seismic sources characterized using an ISC-based catalogue and active shallow fault sources considering geodetic slip-rates assuming a 50% of aseismic slip. In the second half of 2020, the project worked on collecting and consolidating the available geological, geophysical, and geotechnical data for each of the three cities needed to compute site-response (response of the local soil during seismic shaking). When available, the data collected includes the following measurements for each soil layer: shear wave velocity, layer thickness, unit weight, effective pressure, plasticity index, over consolidation ratio, and non-linear material properties. These properties enable the project to perform dynamic analysis of the soil considering non-linear behavior. If some of this data is incomplete or unavailable, the project estimates the parameters using equations derived from literature where possible. Urban Risk Assessment GEM has already developed exposure datasets at the subnational level in Colombia, the Dominican Republic and Ecuador, however the risk assessment activities planned within the context of TREQ require exposure datasets at the urban scale for the three cities. In order to achieve this, the project focused its activities on the development of an exposure model at a district level using the available datasets in collaboration with the local partners. For the Metropolitan District of Quito (DMQ), a total of 29 datasets were used to determine the occupants, structures and replacement costs of the residential, commercial and industrial building stocks. The project used datasets mainly from the official census of population and households (projected to 2020), the city cadastral database (2020), the land use dataset (2016) and the historical development of the city squares from 1760 to 2015. Currently the model has over 1.8 million occupants and 500,000 structures worth 8 billion USD. The structures have been classified by their construction material, lateral load-resisting system, height, approximate age, use and occupancy type. For Cali, Colombia, a detailed exposure model is under development in collaboration with the local partners. The working group include students and professors from EAFIT University, the city planning department (DAPM, Departamento Administrativo de Planeación Municipal), the Risk Emergency Secretariat of Cali (Secretaría de Gestión del Riesgo), and the Colombian Geological Survey (CGS). For the city of Santiago de los Caballeros, the exposure model has been developed in collaboration with the office of territorial planning (POT, Plan de Ordenamiento Territorial). More than 10 different datasets are being used to characterize the urban environment. The baseline dataset is the land use of the city, featuring the current use of the land at a city square level. The project focused on identifying the physical characteristics of the structures in each square using other information owned by the POT, including the construction material, building height and age of homogeneous zones of the city. The Covid-19 pandemic has strongly impacted the activities planned for the TREQ project. At GEM we are committed to transform and adjust the project activities in order to provide the best result and overcome the difficulties imposed by the global pandemic. Despite the challenges, TREQ local partners remain committed to continue with the project activities in their respective countries and to continue with the collaboration, once the transition period is completed.

- Afghanistan Earthquake - GEM Foundation
News Afghanistan Earthquake By: Jul 2, 2018 Share Facebook LinkedIn We express our deepest condolence to the Afghan and Pakistani people over the loss of lives and the destruction caused by the magnitude 7.5 earthquake which struck the Badakshan Province in the Hindukush region, Afghanistan, on 26 October 2015. We hope for a prompt recovery for those injured and appreciate the efforts of humanitarian staff who continue to provide life-saving assistance. The entire collision zone between the Indian and Eurasian tectonic plates is highly prone to earthquakes and is at high risk due to dense population and prevalence of vulnerable building construction. Allied to the immediate recovery response, this event reminds us of the need to emphasise disaster risk reduction and resilience, as key development issues. The GEM Foundation affirms its commitment to build global understanding of earthquake risk and its associated socio-economic impacts, by helping governments – and all who struggle for a more resilient world – with tools and information to assist in reducing that risk and in making sound decisions about building standards and construction quality, consistent with world’s best-practice.

- New GEM-USAID Project Forecasting and Communicating Earthquake Hazard and Risk (FORCE) launched - GEM Foundation
News New GEM-USAID Project Forecasting and Communicating Earthquake Hazard and Risk (FORCE) launched By: Dec 6, 2022 Share Facebook LinkedIn On the heels of the successful completion of the TREQ project partnership this year, GEM and USAID Bureau for Humanitarian Assistance (BHA) are embarking on a new project called Forecasting and Communicating Earthquake Hazard and Risk or FORCE . The project aims to strengthen the capacities and understanding to manage and respond to future earthquake risk by: introducing future growth or change into national and global exposure models to enable the quantification of future disaster losses, including those associated with climate change; developing communication and dissemination tools to maximize the uptake of disaster risk information in policy-making bodies; and improving the reliability of earthquake hazard and risk assessment, in particular in regions that lack information. The project has five implementation components aimed at enhancing the reliability and usefulness of the earthquake hazard and risk information produced by GEM and its partners and expanding GEM product applications to multi-hazard risk assessment considering the current and future conditions of the built environment. These components are: Predicting the evolution of the built environment and population Forecasting future disaster risk due to earthquakes Incorporating infrastructure in exposure modeling for risk assessment Modeling earthquake hazard and risk for small communities Advancing communication and dissemination of risk information The 2.5 year-project, will be implemented in collaboration with local scientists and stakeholders in El Salvador, Nepal, and Bhutan (components 1, 2, and 3), as well as small communities in the Pacific, Indian, and Atlantic Oceans (component 4). “USAID is excited to support this project which targets some of the most seismically vulnerable communities in the world. The project activities, which are designed to evaluate current and future impacts of earthquakes, will not only benefit the project sites but other nations with similar needs and gaps as well,” Lindsay Davis, Earthquake Disaster Assistance Team Manager-USAID/BHA. The GEM Foundation has worked with USAID-BHA over the past years on several projects ( SSAHARA , CRAVE , TREQ ) to develop local and national capacities for earthquake hazard and risk assessment, and to communicate results to the broader community. An event held from November 21-25 in Cali, Colombia to present the results of the TREQ project risk assessment for the city, marked the start of FORCE project’s commitment to keep and improve the training component for technical and non-technical audiences that GEM started in the TREQ project. “With the implementation of the FORCE project, USAID-BHA and GEM will be able to continue its work and build from the outcomes of TREQ project, leading a wider community in building local to regional capacity for assessing and reducing risk,” Catalina Yepes, GEM FORCE Project Manager.

- ‘Rock recorders’ reveal drastic drop in earthquake hazard forecasts for Los Angeles - GEM Foundation
News ‘Rock recorders’ reveal drastic drop in earthquake hazard forecasts for Los Angeles By: Jan 18, 2024 Jan 18, 2024 Share Facebook LinkedIn Photo of one of the precariously balanced rocks studied as part of the project at Lovejoy Buttes. Blue and white tape on the PBR, and red and orange tape on the outcrop below. Yellow tape is used to accurately map the geometry of the base of the PBR. The pattern of joints(fractures) in the granite rock mean that this landscape has an abundance of fragile features. Imperial College London press release ----- Imperial College London scientists have challenged existing earthquake hazard estimates for the San Andreas fault near Los Angeles. The fault marks where two tectonic plates meet, and is responsible for some of California's largest earthquakes. The latest seismic hazard assessment, led by researchers at Imperial, suggests that the hazard of a giant earthquake on the Mojave section of the San Andreas fault area – the closest section to greater Los Angeles – is much lower. The team found that in the unlikely event that a once-in-10,000-years earthquake erupted on the San Andreas fault, the ground would shake 65 per cent less violently than previously thought. The ground shaking uncertainty range was 72 per cent lower than previous estimates – meaning that researchers are much more certain about the new estimate compared to previous estimates. To reach this conclusion, researchers investigated a group of precariously balanced rocks (PBRs) at Lovejoy Buttes, an area found 15 kilometres away from the San Andreas fault. PBRs are naturally balanced rock formations which are found worldwide and provide ancient geological data. Despite their delicate balance, PBRs have survived thousands of years of earthquakes without toppling, revealing insights into prehistorical seismic activity. In this way, they act as ‘inverse seismometers’ or earthquake ‘rock recorders’, as described by the researchers – since the PBRs have not toppled, they record ground shaking of large earthquakes that have not happened. Photo of a precariously balanced rock from elsewhere in southern California, same PBR as in DSCN2456. Senior author Dr Dylan Rood, from the Department of Earth Science and Engineering (ESE) at Imperial, said: “Earthquake hazard scientists are usually limited in their estimation of future earthquake hazard by the fact that modern seismometers have only been recording earthquake shaking for approximately the past hundred years. Therefore, when it comes to less frequent earthquakes happening over tens of thousands to millions of years, estimates become highly uncertain as more assumptions need to be made. “Our groundbreaking ‘inverse seismometers’ technique allows us to forecast large, infrequent earthquake ground shaking more precisely. These precariously balanced rocks overturn the hazard model for the San Andreas fault nearest to Los Angeles.” By precisely dating the age of the PBRs at Lovejoy Buttes and examining their structural fragility (and therefore the likelihood of toppling due to ground tremors), the team at Imperial obtained key information about what intensity of ground shaking can be expected during these rare, powerful San Andreas fault earthquakes. Photo of one of the precariously balanced rocks studied as part of the project at Lovejoy Buttes. The San Andreas fault runs along the base of the San Gabriel Mountains in the background of the photo, ~15 km away. This PBR has been fragile for ~28,500 years, so has survived the ground shaking from all those years of San Andreas fault earthquakes. The findings were presented at the AGU Annual Meeting last month and are published today in Seismological Research Letters . First author Dr Anna Rood, seismic hazard scientist at the Global Earthquake Model (GEM) Foundation and ESE and Civil and Environmental Engineering alumna, said: “We have innovated and implemented the most rigorous PBR validation methods to date. This is an important advance in earthquake hazard analysis, and practitioners should incorporate these methods. Our improved estimates have implications for the seismic hazard assessment of greater Los Angeles, which guide plans for disaster preparation, emergency responses and building codes. While a reduction in hazard may comfort residents of this earthquake-prone region, the magnitude of the inconsistency between our previous hazard estimates and the PBR survival raises important questions about our understanding of earthquake processes.” Researchers emphasised the need for independent data to validate seismic hazard estimates going forward. To improve the accuracy of estimates, they stress the importance of utilising the unique data over the timescales of rare, large earthquakes provided by fragile geologic features such as PBRs. Next, the team will use their inverse seismometer technique to validate seismic hazard estimates for other areas, including the Cascadia Subduction Zone in the Pacific Northwest, USA. Subduction zones generate the largest earthquakes on Earth, yet important questions remain about past and future shaking during magnitude nine megathrust earthquakes.

- GEM building taxonomy version 2.0 | GEM Foundation
Publications GEM building taxonomy version 2.0 Share Facebook LinkedIn Download 2013 | Report This report documents the development and applications of the Building Taxonomy for the Global Earthquake Model (GEM). The purpose of the GEM Building Taxonomy is to describe and classify buildings in a uniform manner as a key step towards assessing their seismic risk. Criteria for development of the GEM Building Taxonomy were that the Taxonomy be relevant to seismic performance of different construction types; be comprehensive yet simple; be collapsible; adhere to principles that are familiar to the range of users; and ultimately be extensible to non-buildings and other hazards. The taxonomy was developed in conjunction with other GEM researchers and builds on the knowledge base from other taxonomies, including the EERI and IAEE World Housing Encyclopedia, PAGER-STR, and HAZUS.
- Global Block Model | Global EarthQuake Model Foundation
A global tectonic block model providing internally consistent fault slip rates derived from joint inversion of geodetic and geologic data, developed to support probabilistic seismic hazard assessment. Products Global Block Model A global tectonic block model providing internally consistent fault slip rates derived from joint inversion of geodetic and geologic data, developed to support probabilistic seismic hazard assessment. Share Facebook LinkedIn Description The GEM Global Block Model is a research dataset that contains a comprehensive, globally complete set of >7000 active faults, combined with a subdivision of the entire Earth surface into ~2000 tectonic plates or microplates (blocks), and a set of three-dimensional meshes of subduction interfaces. The faults are boundaries between blocks, and the slip rates of the faults (proportional to the seismic activity of the faults) are determined by the relative motion of the blocks on either side of the faults. The fault geometries are from a near-complete remapping of Earth’s deforming regions, based in part on existing mapping (such as the previous version of the GEM Global Active Faults Database or GEM GAF-DB), as well as interpretations of high-resolution topography, seismicity and geodetic data, to maximize completeness, accuracy, and mapping style specifically for seismic hazard assessment. The block motions are determined through joint inversion of geodetic velocity data — primarily GNSS observations supplemented by InSAR-derived velocity fields from the COMET LiCSAR processing system — and geologic fault slip rates spanning decadal to Quaternary timescales. The primary output is the set of active faults with complete, internally-consistent slip rates and formal uncertainties, and subduction interfaces with spatially-variable coupling estimated simultaneously with the slip rates. These fault data may be easily used to build and evaluate seismic source models using the OpenQuake software suite. The GEM Global Block Model is a work in progress, and both block geometries and derived fault parameters are subject to revision as new geodetic and geologic data are incorporated.
