2024 UK Offshore Seismic Hazard Maps and Future Developments

Synopsis

The British Geological Survey published the 2024 offshore seismic hazard models, together with accompanying maps for the UK Exclusive Economic Zone (EEZ), to update the previous maps published in 2002. The work was funded by the Industrial Decarbonisation Research and Innovation Centre (IDRIC) and was informed at key stages by external experts who reviewed the project's main components. These offshore maps provide a robust indication of the level of seismic hazard to underpin the planning and design of offshore structures and carbon capture and storage sites in UK waters, e.g. Acorn and HyNet North West areas. This talk will present an overview of the 2024 offshore seismic hazard model and maps for the UK EEZ and how they differ from the 2020 national seismic hazard model and maps for the UK. It will also discuss recent developments in UK seismic hazard analysis to include in the next-generation national seismic hazard maps and how they would affect the seismic hazard results published by BGS in the last five years.

About the speaker

Dr Ilaria Mosca is a seismic hazard researcher at the British Geological Society (BGS). She holds a PhD in seismology from the University of Utrecht (the Netherlands) and has been working for BGS since 2013 after a PDRA in seismic tomography in Germany. Her work is focused on seismic hazard analysis at regional and local scales, including catalogue analysis, simulation of strong ground motions, and assessment of realistic uncertainties for different components of the hazard analysis. Dr Mosca has worked on numerous scientific and commercially funded seismic hazard projects in the UK and worldwide, leading them since 2020. She represents the BGS in the British Standards National Committee B/525/8 for Seismic Regions and is an ExeCom member of the European Seismological Committee.
