Third GEM-EGU Summer School on GeoHazards Risk Assessment

September 7-11, 2026

University of Aveiro, Portugal

OVERVIEW

This summer school offers comprehensive training in earthquake impact assessment through a multi-hazard approach, covering ground shaking, liquefaction, landslides, and tsunamis.


Participants will learn how to perform earthquake scenarios using the OpenQuake-engine, drawing on recent events such as the 2023 Türkiye earthquake and the 2025 Myanmar earthquake.


This year’s programme also includes sessions on AI for exposure and vulnerability modelling, and on augmented and virtual reality for risk communication.


Participants will also have the opportunity to obtain an official OpenQuake-engine (Scenarios) certification.

Syllabus

At the end of the school, what will I be able to do?

Participants will learn how to perform hazard and risk analysis using:

  • open-source tools, in particular the OpenQuake engine developed by the GEM Foundation, and open models and datasets covering the District of Lisbon

  • (Portugal), or datasets from their own regions.


They will be able to:

  • model earthquake scenarios using OpenQuake,

  • work with open data, models, and tools for hazard and risk analysis,

  • understand the main components required for multi-hazard

  • risk assessment,

  • explore the use of AI for exposure and vulnerability modelling,

  • understand how AR and VR can support risk communication,

  • present complex risk results to different stakeholders.


Who will teach?

  • Vitor Silva (University of Aveiro, GEM Foundation)

  • Finn Løvholt (Norwegian Geotechnical Institute)

  • Catalina Yepes (GEM Foundation)

  • Catarina Costa (GEM Foundation)

  • Lana Todorovic (GEM Foundation)

  • Christopher Brooks (GEM Foundation)

  • Karim Aljawhari (GEM Foundation)

  • Daniel Gomez (GEM Foundation)

  • Marzia Santini (EU JRC)

  • Hugo Rodrigues (University of Aveiro)

  • Daniel Emilio (University of Aveiro)
