Deformation in subduction zones is thought to be highly variable on multiple temporal and spatial scales. I will present work that quantifies patterns of deformation and vertical land movements on several time scales in the Hellenic Subduction Zone, the largest and most active Mediterranean subduction zone, from Miocene to today. Combining these observations is crucial to derive a coherent geodynamic model, estimate the subduction zone's energy budget, and assess natural hazards. However, subduction zone topography is not only dependent on the tectonic uplift rates but also the type and rates of surface processes. Especially, differences in lithology can have a profound effect on subduction zone topography and surface processes. I will show how carbonate bedrock strongly affects the topography, and denudation mechanisms in the forearc of the Hellenic Subduction Zone and other sites around the Mediterranean.​

SZ4D presents International Webinars, a series where the working groups invite international scientists to present on different topics relevant to their research and region. SZ4D values international voices and invites you to learn from these folks.
