BACKGROUND
The TREQ Project is designed to demonstrate how earthquake hazard and risk assessment can inform decision makers in the development of risk reduction policies, as well as how earthquake risk can be properly communicated to stakeholders and the public in general.
Specifically, the project aims to develop capacity for urban earthquake risk assessment in Latin America (Quito (Ecuador), Cali (Colombia), and Santiago de los Caballeros (Dominican Republic), while the second part will produce training, educational and communication materials that will enhance the understanding of earthquake risk worldwide.
This program targets a wide spectrum of stakeholders, categorized into four main groups: governance (decision-makers/public authorities), industry (practitioners and professionals), academia (researchers and professors), and the community.
FUNDING PARTNER
The TREQ project, which runs from 2020-2021, is funded by The United States Agency for International Development (USAID) an independent agency of the United States federal government that is primarily responsible for administering civilian foreign aid and development assistance.

TREQ Project
Training and Communication for Earthquake Risk Assessment (TREQ)
MANUAL FOR HAZARD MODEL DEVELOPMENT
This manual presents the basic concepts of classical PSHA and the wide spectrum of alternatives to model seismicity and uncertainties (epistemic and aleatory) in the OpenQuake-engine. Probabilistic Seismic Hazard Assessment (PSHA) is the principal methodology for assessing the potential hazard posed by earthquakes. The hazard maps generated with the hazard calculator are widely used in national seismic codes for hazard zonation and structural design provisions.
OPENQUAKE ONLINE TRAINING
The OpenQuake online training is designed for an audience with a diverse background and expertise. Participants will learn the main concepts of earthquake risk assessment, along with the basic features of the engine. The training activities have been tailored for beginner users, and are divided into four modules that cover different types of calculations using the OpenQuake-engine.

TRAINING THE TRAINERS
TREQ has engaged and collaborated with five university professors from Latin America to conceptualize, create and implement a unified course for the study of seismic risk at the university level. Brochures in English and Spanish further explain the concept behind this initiative and outline the early results and experiences of the professors from Colombia, Costa Rica, El Salvador, Guatemala and Mexico.
If you are a professor and would like to implement a similar course in your institution, contact us at treq@globalquakemodel.org.
TRAINING OVERVIEW
The OpenQuake online training is designed for an audience with a diverse background and expertise. Since 2020, 20 personalised training sessions for Module II have been offered to small groups, allowing a close interaction and dynamic participation. Around 400 participants from 56 countries (more than 140 cities) have registered covering a total of 60 hours of live training. Most of the participants of Module II have manifested the interest in continuing the training for Modules III and IV, and priority in the registration process will be given to them.
Raising Risk Awareness: workshops for the general public
Medellin, Colombia. The TREQ project successfully conducted training activities to improve earthquake risk awareness. The training was designed in collaboration with AMVA (Área Metropolitana del Valle de Aburrá), SIATA and EAFIT University. 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. The events were held on February 18th and 21st in Medellin, Colombia.
Communication activities will continue to be held in the city as part of the collaboration with the local offices.

Seismic hazard analysis at the urban scale
This study demonstrates the importance of incorporating local soil response when the goal is to model hazard at the urban scale with a higher level of detail compared to more standard approaches using Vs30. It contains the description of the methods used and final urban hazard results for the TREQ cities.
Probabilistic seismic hazard model for the Dominican Republic
This document describes the development of a national PSHA model for the Dominican Republic in five sections: 1) seismotectonics; 2) major datasets that were used to build the model; 3) seismic source characterization, including the analyses performed to validate the model components; 4) seismic attenuation properties of Hispaniola and the ground motion model logic tree that was selected for the Dominican Republic; and 5) main seismic hazard results computed from the model using the OpenQuake Engine, focusing mostly on the city of Santiago de los Caballeros. The last section discusses how the results compare to those of former models, and thus how this study has changed our understanding of seismic hazard in the Dominican Republic.
Probabilistic Seismic Hazard Analysis (PSHA) Training Manual
This manual presents the basic concepts of classical PSHA and the wide spectrum of alternatives to model seismicity and uncertainties (epistemic and aleatory) in the OpenQuake-engine. Probabilistic Seismic Hazard Assessment (PSHA) is the principal methodology for assessing the potential hazard posed by earthquakes. The hazard maps generated with the hazard calculator are widely used in national seismic codes for hazard zonation and structural design provisions.
Seismic Hazard Results (rock and soil conditions)
This document describes the hazard calculations that were performed for rock and soil conditions using the OpenQuake Engine (Pagani et al. 2014), on a grid covering the city (1km spaced) and for 10% and 2% in 50 years probabilities of exceedance (PoE). Several structural periods (i.e. peak ground acceleration and spectral acceleration at 0.2, 0.5, 1.0 and 2.0 seconds) were considered. Uniform hazard spectra (UHS) were derived using these spectral periods for the PoE considered. In addition, disaggregation analysis was performed for each city in order to understand which sources contribute most to the hazard computed for rock condition for each city.
PSHA models and datasets for urban hazard assessment
This document describes the state-of-the-art of the seismic hazard modelling in the three TREQ countries involved, as well as the criteria used to select the best model available to compute ground shaking on reference bedrock for each city and a brief description of the sources affecting each city.
