Summary
The Training and Communication for Earthquake Risk Assessment (TREQ) Project was 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.
Objectives
The project was organized into two main parts. The first one aimed to develop capacity for urban earthquake hazard and risk assessment in Latin America, Quito (Ecuador), Cali (Colombia), and Santiago de los Caballeros (Dominican Republic); while the second part was to develop training, educational and communication material to enhance the understanding of earthquake risk worldwide. The program was tailored for 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.

Urban risk assessment in Latin America and the Caribbean
The following deliverables were generated in this component: seismic hazard and risk assessment at the urban scale for the three TREQ cities: Quito (Ecuador), Cali (Colombia), and Santiago de los Caballeros (Dominican Republic). State-of-art models were developed for each city in close collaboration with local partners. The input models and results are available at the URL address below:

Improving global capacity for seismic hazard and risk
This part of the program was designed to improve the understanding and awareness of earthquake hazard and risk, and to help bridge the gap between the information produced in detailed hazard and risk assessment studies and its communication to a wide variety of stakeholders (which range from local experts with the remit to assess seismic risk to decision-makers responsible for the implementation of risk reduction measures).
a. Website for OpenQuake online training
The OpenQuake online training was designed for different types of audience with diverse background and expertise. Through this platform, participants interacted with GEM scientific and technical teams to learn the main concepts of earthquake risk assessment, along with the basic features of the engine.
b. OpenQuake manual in online format
The official manual has been converted from latex into reStructuredText format made possible by @USAID support. The new manual is now online in HTML format and can be accessed at:
c. Video tutorials on seismic hazard and risk analysis using OpenQuake
The project has produced 15 videos on technical training using the OpenQuake-engine (in English and Spanish), 7 videos with material to disseminate the models and results of urban risk assessment in the TREQ cities, and 2 videos for communicating earthquake risk to the general public.
d. Manual to perform seismic hazard analysis
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.
e. 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.

Communicating and raising earthquake risk awareness
The activities in this component focused on raising awareness of the public on earthquake hazard and risk by training a diverse group of disaster risk reduction (DRR) professionals together with personnel in charge of communicating risk to the public, and by conducting community-based workshops in selected areas of the pilot cities by those who were trained by the project.
