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.

News Raising Earthquake Risk Awareness: TREQ’s community workshops for the general public By: Mar 16, 2022 Share Facebook LinkedIn The USAID-supported TREQ project successfully conducted an earthquake risk awareness training for risk management practitioners at the community level. The sessions, held on February 18th and 21st in Medellin, Colombia were designed in collaboration with local partners AMVA (Área Metropolitana del Valle de Aburrá), Sistema de Alerta Temprana de Medellín y el Valle de Aburrá (SIATA) and EAFIT University. The group has also developed a video to support the earthquake risk awareness sessions . A diverse group in charge of disaster risk reduction (DRR) activities was trained, together with personnel in charge of communicating risk to the general public on topics ranging from understanding earthquakes to assessing earthquake risk. A document designed to support people interested in facilitating these types of sessions will be available on the TREQ website soon. Recently, one of the project partners, SIATA has re-echoed what they have learned in a series of meetings at the community of Andalucia in Caldas. Officers from SIATA discussed what people think of when they hear the word ‘earthquake’. The group deliberated on this question to clarify misconceptions and reinforce the facts about this natural phenomenon. TREQ’s communication activities will continue to be held in the city of Medellin as part of the collaboration with the local offices and partners. Visit the TREQ website for more information about the project. No images found. GALLERY 1/25 Gallery VIDEO RELATED CONTENTS

Products and Services Strategy document of GEM Foundation GEM PRODUCTS and SERVICES STRATEGY DOCUMENT The GEM Products and Services Strategy aims to sustainably provide accessible information. GEM will expand its offerings, leveraging its tools and data to meet the diverse needs of providers, users, and the broader DRR community. OVERVIEW FAQs 0. Overview The key objective of GEM’s Products and Services Strategy is to continue to make all information freely available, with an emphasis on open access, while at the same time assuring the sustainability of the organisation. Although GEM has been continuously and generously supported by public and private institutions for more than 15 years, the development of products and services to meet the existing and future needs of the disaster risk reduction community requires additional support and funding, which GEM has sought through engaging in more institutional projects and through more investment in commercial products and services. GEM’s products and services are released through different mechanisms depending on the product, and these can be simply categorised in three ways: open software, data and models (under different open license conditions described here); freely available software, data and models available for non-commercial, public good use, following a license request; commercial-use products and services (i.e. subject to a license fee). It is worth underlining that all of GEM’s products are always available freely for non-commercial, public good use, regardless of the mechanism under which they are primarily released. As a non-profit organisation, any revenue derived from commercial sales of products or services are reinvested to fund GEM’s core programmes (i.e. advancing capabilities in earthquake and multi-hazard risk, pioneering scientific risk assessment methods, and expanding risk and resilience applications to downstream users), with an emphasis on providing support to countries in the Global South Frequently Asked Questions (FAQ) This section provides detailed information on how to access GEM’s Open products (Part A) and License request products (Part B), including how to access these products for free. This section also contains specific explanations of the most common questions about GEM’s products and services. overview faq A. Open Products A.1 Where can I find and download the full list of GEM’s open products? From the Products webpage (https://www.globalquakemodel.org/products ), you can select to see a list of products with open licenses, as shown in the video below. A.2 What are GEM’s top or flagship open products? GEM’s flagship products are OpenQuake software and the Global Earthquake Hazard and Risk Models and Maps. A.3 Why does GEM develop open products? GEM develops open products to make high-quality scientific products in earthquake hazard and risk analysis readily available for public good. Most high-calibre software or data are closed/proprietary or very expensive. To break this barrier, GEM releases open products in order to promote access to and sharing of information, to promote collaboration and transparency, and thereby build trust among partners and the public. A.4 What is an open product, and how does GEM define open? An open product is a digital or technology-based product that is free of cost and accessible, though access may be governed by specific conditions of use. An open product can be a software (open source code), a scientific publication (open access) or a database (open data). The GEM Foundation distributes open-source software and open data. With limited exceptions, intellectual products by the GEM Foundation are released with open licenses, such as the GNU AGPL for software and the Creative Commons licenses for creative contents, datasets and models. You can check the full details here . A.5 What license types govern GEM’s open products? Can I use GEM’s open products for commercial purposes? Many of GEM’s products are released under a CC BY-SA license. These products may be used commercially provided any distribution of derived products is attributed to the GEM Foundation (BY = by attribution) and they are redistributed with the same (SA = share-alike) license. If the license is CC BY-NC-SA, in addition, the product or its derivatives may not be used commercially (NC = non-commercial). You may request to use a GEM product under different license conditions (e.g. for commercial use) by filling in a License Request form (see Part B below). GEM’s OpenQuake software and related tools are released under an AGPL license, which also has no commercial restrictions, and derived products may only be distributed under the same open license. You can check the full details of our licensing terms here . In addition, please refer to GEM’s terms of use and licensing policy . B. License Request Products B.1 Why is GEM not providing all of its products openly? Some of the more commercially attractive products (e.g. higher resolution datasets) are not made openly available, but are instead only shared through the signing of a license agreement. In this case, we grant access under a more restricted license that forbids distribution or disclosure and requires signing by GEM and the licensee in order to better assure accountability for the confidentiality of the information. For commercial use of those products, GEM requests a commercial license fee to generate additional income to further support the development of free and open products. Nevertheless, all products that are made available for a fee are also available for free for non-commercial, public-good applications (i.e. academic, government or humanitarian projects, etc.). B.2 What products are being offered for a fee? From the Products webpage (https://www.globalquakemodel.org/products ) you can select to see a list of products with NC (non-commercial) or custom licenses, as shown in the screenshot below. For commercial use of those products, GEM requests a commercial license fee to generate additional income to further support its mission. B.3 How does GEM use the income from products made available for a fee? Revenue generated from commercial licenses is reinvested in public good activities with particular emphasis on the Global South. B.4 I’m a government officer and working on a DRR project and the product I need is not openly available. How can I obtain that product? All products on the GEM website have a License Request button.
