A ground motion logic tree for seismic hazard analysis in the stable cratonic region of Europe: regionalisation, model selection and development of a scaled backbone approach
Regions of low seismicity present a particular challenge for probabilistic seismic hazard analysis when identifying suitable ground motion models (GMMs) and quantifying their epistemic uncertainty. The 2020 European Seismic ... -
A regionally-adaptable ground-motion model for shallow crustal earthquakes in Europe
Kotha, Sreeram Reddy; Weatherill, Graeme; Bindi, Dino; Cotton, Fabrice (Bulletin of Earthquake Engineering, 2020-05-21)To complement the new European Strong-Motion dataset and the ongoing efforts to update the seismic hazard and risk assessment of Europe and Mediterranean regions, we propose a new regionally adaptable ground-motion model ... -
A regionally-adaptable “scaled backbone” ground motion logic tree for shallow seismicity in Europe: application to the 2020 European seismic hazard model
Weatherill, Graeme; Kotha, Sreeram Reddy; Cotton, Fabrice (Bulletin of Earthquake Engineering, 2020-07-07)The selection of ground motion models, and the representation of their epistemic uncertainty in the form of a logic tree, is one of the fundamental components of probabilistic seismic hazard and risk analysis. A new ground ... -
Applying Conservation of Energy to Estimate Earthquake Frequencies from Strain Rates and Stresses
Ziebarth, Malte J.; von Specht, Sebastian; Heidbach, Oliver; Cotton, Fabrice; Anderson, John G. (Journal of Geophysical Research: Solid Earth, 2020)Estimating earthquake occurrence rates from the accumulation rate of seismic moment is an established tool of seismic hazard analysis. We propose an alternative, fault-agnostic approach based on the conservation of energy: ... -
Regional broad-band ground-shaking modelling over extended and thick sedimentary basins: an example from the Lower Rhine Embayment (Germany)
Pilz, Marco; Cotton, Fabrice; Razafindrakoto, Hoby Njara Tendrisoa; Weatherill, Graeme; Spies, Thomas (Bulletin of Earthquake Engineering, 2020-11-16)The simulation of broad-band (0.1 to 10 + Hz) ground-shaking over deep and spatially extended sedimentary basins at regional scales is challenging. We evaluate the ground-shaking of a potential M 6.5 earthquake in the ... -
Role of Poroelasticity During the Early Postseismic Deformation of the 2010 Maule Megathrust Earthquake
Peña, Carlos; Metzger, Sabrina; Heidbach, Oliver; Bedford, Jonathan; Bookhagen, Bodo; Moreno, Marcos; Oncken, Onno; Cotton, Fabrice (Geophysical Research Letters, 2022-05-09)Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere‐asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and ...
