Georisk & Environment  

The main focus of the Georisk and Environment unit is related to the integration of various geohazard assessment approaches with a focus on seismically active mountain regions.  
Integration is considered at different spatial and temporal scales using GIS and remote sensing techniques, Subsurface imaging through various Geophysical methods, Geological and Numerical Modelling, Visualization (Virtual Reality).

The group is involved in multiple international projects in Belgium, SE Europe, Central Asia, Central Africa, Haiti, Armenia, China.

Application to seismically active regions of Haiti

by Valmy DORIVAL


presented in the Geology building of Liege University (B18, room R125), on March 2, 2026, at 3pm.

PhD director: Dr. Hans-Balder Havenith (Liege University); co-director: Dr. Kelly Guerrier (Université d’Etat d’Haïti).

GEORISK - AR Model Viewer

Augmented Reality model viewer showing examples of fossiles and minerals. Enables comparative visualisation between two virtual models and/or real counterparts. Annotations with references and explanations can be displayed on the models and in the menu. Using stereokit it also features a VR mode as well as controller and free hand interaction.

GEORISK - Geology Tour Activity

In this rather long VR-capture a comprehensive tour of all the included data und functionality is given.
It includes 3D visualizations ranging from fundamental Geology topics to Paleontology and Mineralogy.

Using Unreal Engine's template for collaborative applications it allows multiple desktop and VR systems to be connected and to communicate in real time.

The visualization of planet Mercury is based on data from NASA's Messenger mission and also includes a layer from the integrated publication.

The included fossile modeles have been created by the Evolution & Diversity Dynamics Lab and can be found here. The animated dinosaur models have been exported from the Microsoft 3D Viewer application. A peacock sound near the pterodactyl as well as the iconic T-Rex roar from the first Jurassic Park movie may also be triggered during the demo. Text details on the Sketchfab models can be triggered inside the visualization.
An interactive 3D representations of the related scientific publication has been included as scientific reference.

The mineralogy part has been developed in close collaboration with the Laboratoire de Minéralogie et de Cristallochimie. The crystal models are based on data from the American Mineralogist Crystal Structure Database.They have been generated and exported from VESTA.

GEORISK - Santorini bathymetry

AR demo including Santorini bathymetry & H/V data mixed with streamed Cesium Ion layers provided through Google Earth and Bing maps services. Made with the Unity Engine for the Meta Quest3 headset.

GEORISK - Palaeozoology in VR

This interactive visualization uses the Unreal Engine with the Landscape Pro plugin.
It contains models and animations from Sketchfab and the Microsoft 3D Viewer application.
Many of the contained fossils have been scanned and modeled by the Evolution & Diversity Dynamics Lab and can be found here. Additional information about the finite elements simulation code used for the inferior feline jaw and the corresponding research can be found by following the corresponding links. The first few seconds of the iconic Jaws movie soundtrack are playing close to the shoreline near the Megalodon. And a peacock sound can be heard near the pterodactyl as well as the T-Rex roar from the first Jurassic Park movie may also be triggered during the demo.
Text details on the Sketchfab models can be triggered inside the visualization.
Interactive 3D representations of subject related scientific publications and posters have been included in the demo as references.

GEORISK - CaCO3 and Minerals in Mixed Reality

Compare Calcite and Aragonite structures on the macroscopic and the atomic scales. Developed with stereokit this Coulomb physics demo includes crystal structures prepared with help from the "Laboratoire de Minéralogie et de Cristallochimie". They're based on data from the American Mineralogist Crystal Structure Database, and have been exported from VESTA. The included mineral models from Sketchfab: Most of the shown Specimen are from the teaching collections of the Paleontological Research Institution. Models by Emily Hauf.
