Note that keynote talks will be 40 min and other talks 30 min, so the time assignments will differ by ten minutes depending on the session configuration. Posters will be visible all three conference days. Presenters are encouraged to hang up their posters already during the Welcome and Ice breaker time. Each day, we will have a set of topic-specific lightning talks to foster awareness of the posters. These ightning talks will be 2 minutes each. For details see TECHNICAL.

To save ressources we will not provide printed versions of the full abstract book. The pdf file (71 pages, 1.8 MB) is available, here.

Session 1

When a slab sinks into the mantle during subduction processes, the physical characteristics of the mantle obviously influences slab penetration and migration. The lithosphere and asthenosphere rheologies and the processes occuring in the mantle are yet not fully understood, nor do their influence on the subduction dynamics and the development of topography above subduction zones. This session aims at studying the role of various deep processes and Earth layers rheology on subduction initiation and evolution as well as on the development above the subduction zone.

Session 1A Deep processes and characteristics acting on plate boundaries and topography

Processes happening at the base of the lithosphere as well as the lithosphere’s rheology are of great influence on subduction dynamics as well as resulting topography.This session highlights how the lithosphere’s rheology and thickness as well as underplating processes affect the lithosphere behaviour in subduction zones in terms of deformation patterns, slab retreat kinetics and topography evolution.

Keynote presentation: Rheological continuity at the Lithosphere-Asthenosphere Boundary: implications for plate dynamics and deformation, by Fanny Garel, University of Montpellier.

Session 1B Subduction zone initiation, evolution tracking and emerging structures

Subduction initiation remains a debated issue. In this session we will start by an analogue study on subduction initiation in oceanic domain as well as at passive margins. After having looked at the onset of subduction, we will focus on seafloor spreading as tool to assess subduction zone behavior over time as well as a way to get insights on mantle dynamics along with the slab migration. Along with slab retreat, the formation of structures such as microcontinents can be observed. Their formation process will be the focus of the last part of this session.

Keynote presentation: Eocene subduction west of North America-causes and effects, by Carmen Gaina, University of Oslo.

Session 2

Tectonics and surface processes control the topography and natural hazards above subduction zones . This day will focus on different time-scales of upper plate deformation and how surface processes can be used to extract geodynamic, tectonic and climatic forcings acting on subduction zone topography.

Session 2A: Active tectonics and earthquake hazards in subduction zones

Subduction zones represent the main seismic hazard globally. This session aims to understand the role of active faulting and earthquake hazards in the upper and lower plate, and how the seismic cycle relates to longer term deformation and topography.

Keynote Presentation: Topographic modulation of fault kinematics in the Himalaya and Tibet, by Richard Styron, University of Michigan.

Session 2B: Using surface processes to constrain tectonic signals

Surface processes act on all subaerial regions of subduction zones and can contain a lot of information about tectonics. This session will present useful tools in extracting information from surface evolution and case studies of constraining tectonic signals from topography.

Keynote Presentation: Surface processes above subduction zones – importance, interactions and implications, by Alexander Whittaker, Imperial College London.

Session 2C: Impact of slab and mantle dynamics on long-term upper plate deformation

The slab and the upper plate are coupled and therefore changes of the slab behavior with time can excert a strong tectonic signal in the crust. This session looks at regional examples of upper plate deformation in subduction zones and the potential role of mantle dynamics.

Session 3

The Mediterranean domain is the western part of the Alpine-Himalayan orogenic belt, one of the largest and most prominent suture zones on Earth. The Mediterranean domain ranges from the Gibraltar Strait in the west to Arabia in the east. It results from the subduction and closing of different branches of the Tethyan oceanic realm and the subsequent collision of the African and Arabian continental plates with Eurasia. Complex interactions among major and smaller plates, featuring the presence of subduction zones at different evolutionary stages have produced a long-lasting geological record. This record has progressively grown as a comprehensive test site to investigate fundamental plate tectonics and the link between deep and shallow processes with multidisciplinary studies. Advances in a variety of geodynamic, geophysical and geological fields provide a rich and growing set of constraints on the crust-lithosphere and mantle structure, as well as tectonics and geodynamic evolution of the Alpine realm.

Session 3A : Present day deep structure in the Western Mediterranean

Imaging the present-day deep structure is important to understand the evolution of subduction zones and serve as a crucial constrains for the geodynamic evolution models. This session is focused on imaging the Western Mediterranean integrating data from potential field, passive seismology and GPS.

Keynote Presentation: Deciphering the Betic orogen through its lithospheric structure by Flor de Lis Mancilla , University of Granada.

Session 3B: In contrast to Mediterranean

The Alpine realm represents a unique opportunity to investigate geodynamics of the complex interplay of plate subduction, collision, and back-arc extension. In this session, we bring together different perspectives on the evolution of the Mediterranean --from the Aegean to the Arabian plate--, to compare the main geodynamic processes that have shaped the closure of the Tethys.

Keynote presentation: Magmatic forcing of Cenozoic climate by Pietro Sternai, University of Milano-Bicocca.

Workshop Simplify Your Science

This 90 minute practical workshop will introduce you to the principles of effective science communication. You will be given a set of criteria to help you simplify your message, and you will learn to asses your own presentations more critically. The workshop will conclude with an exercise where you will simplify and summarise your own research for social media, with the help of the partner teachers.

SUBITOP decisively forges synergies between academia and industry, but also between academia and school teachers. This workshop will be steered by several of the SUBITOP partner school teachers.

Demystifying science communication: tips for making your science pop

Never before has the general public had more access to science; and yet, science is experiencing ever-growing mistrust in the public sphere. In this workshop, we'll explore this dichotomy and the role scientists and effective science communication have to play in dispelling it. Through a range of interactive activities and exercises, attendees will learn how to communicate their science in an engaging and fun way while at the same time tailoring their delivery to a diverse audience.
