Shallow bathymetry from pléiades data: the case study of the Grindavik volcanic crisis

International audience On November 10, 2023, the town of Grindavik on the Reykjanes peninsula (Iceland) was evacuated due to the propagation of a shallow magmatic fissure near the town. We programmed Pléiades images on the area via the CIEST2 initiative. Due to the vicinity of the affected area to t...

Description
Summary:International audience On November 10, 2023, the town of Grindavik on the Reykjanes peninsula (Iceland) was evacuated due to the propagation of a shallow magmatic fissure near the town. We programmed Pléiades images on the area via the CIEST2 initiative. Due to the vicinity of the affected area to the ocean, the lava flow might reach the water modifying submarine topography. Our goal is to test a new space-based method to measure shallow bathymetry and possible submarine lava flow volume in shallow water.
