FIRELINE-ICE will investigate the offshore continuation of the Reykjanes Peninsula rift system near Grindavík, Iceland, where repeated dyke intrusions, faulting, and explosive eruption-potential pose escalating risks to critical coastal infrastructure. The project will acquire and interpret new high-resolution multibeam bathymetry and seismic reflection data to map seabed and sub-seabed fault networks, rift graben architecture, and magmatic intrusions. These data will underpin models of deformation, pyroclastic density current (PDC) pathways, and broader geotechnical constraints affecting offshore development. By integrating geophysical imaging with hazard modelling, the project will deliver a robust framework for risk mitigation and resilience planning, while fostering collaboration between Icelandic, UK, and Scottish research institutions and enhancing preparedness for future offshore geohazards.

The ICF award will support a visit by BGS Scotland (Lyell Centre) to Iceland to formally initiate the FIRELINE-ICE collaboration with ÍSOR and introduce partners from the University of Edinburgh and the University of Iceland. The visit includes field reconnaissance at Grindavík, marine survey planning, and technical discussions to align expertise across institutions.

BGS will contribute marine geoscience and seabed/sub-seabed imaging; ÍSOR will provide local geological knowledge, contacts, logistics, and fault mapping; the University of Edinburgh will lead on pyroclastic density current hazard modelling; and the University of Iceland on conceptual volcanic systems modelling of the Sundhjúkur fissure swarm.

The visit will also explore co-funding via Icelandic agencies and develop a detailed work plan for an ERC Synergy Grant proposal. This activity will strengthen collaboration, align scientific priorities, and ensure a competitive, well-integrated European funding application
