Studying the Effect of Geometrical Features on Megathrust Earthquakes using Natural Observations and Seismotectonic Numerical Models

Project description

How does the seafloor's landscape impact earthquakes?

Subduction zones are regions where one tectonic plate dives below the other, which leads to large earthquakes and associated tsunamis. Topographic features on the subducting seafloor are considered central in segmenting the plate interface into seismic and aseismic zones. They may thus control where earthquakes occur and how far they propagate. However, understanding the role of these features is difficult due to limitations in time and space in observations and modelling of crustal deformation in 2D and 3D. The EU-funded SEGMENT project will integrate pioneering modelling tools to study how and to what extent the subducting seafloor's topography impacts subduction earthquakes. Specifically, the project will combine seismotectonic numerical models with probabilistic natural observations from geodesy and seafloor roughness to obtain complementary information and quantify elusive links.
