Eruption at Fagradalsfjall and Litli-Hrútur 2021-2023

Three-dimensional models of the eruption at Fagradalsfjall and Litli-Hrútur are developed in collaboration with the Icelandic Civil Protection and Emergency Management, the National Land Survey of Iceland and the University of Iceland.

The Icelandic Institute of Natural History operates an aerial photography laboratory where geological mapping is used alongside image measurement technology to create three-dimensional models, a process known as photogrammetry. In this process photographs are taken from the air via plane or drone and the images are used to create the models. This method has been useful in mapping the eruption area in Reykjanes, with the three-dimensional models it is possible to estimate the volume and thickness of the lava, how much lava is coming out (discharge rate) and much more.

The three-dimensional models are made by the imaging team of the Icelandic Institute of Natural History. The images are taken from an airplane and then processed and created in the software Agisoft Metashape. The models are then uploaded onto Sketchfab. One of the models that has been published is from before the eruption, but other models show the lava field with around weekly intervals.

With the 3D models, it is possible to follow the progress of the eruption and they are primarily intended for information and entertainment. You can contact the institute for more detailed information and data.
