The 2026 GEM Conference: From faults to future scenarios

June 23-25, 2026
(Live Streaming on YouTube on June 23rd)

University of Zagreb, Croatia

OVERVIEW

The 2026 GEM Conference will take place in Zagreb, Croatia, from 23-25 June 2026, hosted by our partners at the Croatian Centre for Earthquake Engineering, Faculty of Civil Engineering, University of Zagreb, Croatia.


At this three-day event, GEM will release the 2026 version of its global seismic hazard and risk models, marking a major milestone in our ongoing mission to advance earthquake risk understanding worldwide. The conference will feature a range of scientific and technical sessions, panel discussions, and community presentations, providing an open forum for collaboration and knowledge exchange.


AGENDA | SCIENTIFIC PROGRAM

Below is the overview of this 3-day conference, which will take place between 23rd and 25th June 2026. We will be releasing the 2026 version of GEM's global seismic hazard and risk models at this conference, and we will have a number of sessions that are open to contributions from the community.

Abstract

Exploring new data analysis techniques on an extended earthquake catalogue for evaluating seismic hazard in Europe

Jochen Woessner

Senior Principal Modeller

Moody’s RMS

Earthquake catalogues are a crucial resource for most seismological investigations and form the foundation of every probabilistic seismic hazard assessment (PSHA). This paper presents new developments in processing and analyzing an updated European earthquake catalogue for PSHA purposes. The updated catalogue expands on the work of the 2020 European Seismic Hazard Model (ESHM20) and now covers the period from 1000 to the end of 2021, contributing with an additional 4,500 revised earthquakes with magnitudes greater than 3.5 in the region. Using this dataset, we test various state-of-the-art procedures for analyzing spatial patterns, magnitude distributions, and seismicity rates. In particular, we explore the use of Machine Learning (ML) techniques to address long-standing problems, such as earthquake declustering. We introduce a new objective tectonic classification methodology that improves on current standards and enables the grouping of previously unclassified events via an iterative clustering approach. This work lays the foundation for creating a new standardized workflow for developing the next generation of the Moody’s RMS European seismic hazard model.

TRANSPORTATION

Transportation from Zagreb Airport

The conference venue is the Faculty of Civil Engineering, University of Zagreb, located at Fra Andrije Kačića-Miošića 26, 10000 Zagreb.


By taxi, Uber or Bolt

The fastest option is to travel directly from Franjo Tuđman Airport Zagreb to the venue by taxi, Uber or Bolt.


Use the following destination: Faculty of Civil Engineering, University of Zagreb / Građevinski fakultet Sveučilišta u Zagrebu, Kačićeva 26


Estimated travel time: 25–35 minutes, depending on traffic.Estimated fare: €30–36 by official taxi; approximately €15–30 by Uber/Bolt, depending on demand.


Official taxis are available outside the arrivals area. Participants using ride-hailing apps should follow the app instructions for the designated pick-up point.


By airport shuttle bus and tram

The Pleso Prijevoz airport shuttle runs between Zagreb Airport and Zagreb Central Bus Station / Autobusni kolodvor.


Estimated shuttle travel time: 35–40 minutes. Estimated fare: approximately €9 one way

From Autobusni kolodvor, take tram line 2 toward Črnomerec and get off at HNK2 – Adžijina or Vodnikova. From there, it is a short walk to the venue.


Estimated total travel time: 50–60 minutes, depending on waiting time and traffic.


By public bus and tram

A lower-cost option is to take ZET bus line 290 from Zagreb Airport to Kvaternikov trg.


Estimated bus travel time: 45–50 minutes.


From Kvaternikov trg, take tram line 12 toward Ljubljanica and get off at Trg Republike Hrvatske or Vodnikova. From there, it is a short walk to the venue.


Estimated total travel time: 60–75 minutes, depending on waiting time and traffic.


ZET tickets are valid for Zagreb public buses and trams. Tickets may be purchased at kiosks, ticket offices, from the driver, or through the Moj ZET app. Please validate your ticket when boarding.


By train

There is currently no direct train or metro connection from Zagreb Airport to the city centre or the conference venue. Participants arriving by train should use Zagreb Glavni kolodvor as the main railway station and continue to the venue by tram, taxi, Uber or Bolt.


Notes

Travel times and fares are estimates and may vary depending on traffic, time of day and service availability. Participants are advised to check the latest schedules before travelling.
